has been tested with Visual Studio, Visual Studio Code and CLion. - -The raylib source code is included in the libs folder as it is much easier than including prebuilt binaries for every platform and configuration. - -Building from the cmake file will build both raylib and `src/main.c` which includes a basic example of a raylib program. - -The example in `src/main.c` uses an example image located in the `assets` folder. - -The absolute path to the assets folder is defined by a macro `ASSETS_PATH` in the CMake file automatically which is useful during development. If you plan on releasing or sharing your game consider manually setting the value of the `ASSETS_PATH` macro. - -## How to use with C++ -To use with C++ simply rename `main.c` to `main.cpp` and then

There were lots of things I found confusing and some function names were not clear enough for most of the students; not to mention the lack of transparencies support and no hardware acceleration. - -So, I decided to create my own library, hardware accelerated, clear function names, quite organized, well structured, plain C coding and, the most important, primarily intended to learn videogames programming. - -My previous videogames development experience was mostly in C# and [XNA](https://en.wikipedia.org/wiki/Microsoft_XNA) and I really loved it, so, I decided to use C# language style notation and XNA naming conventions. That way, students were able to move from raylib to XNA, MonoGame or similar libs extremely easily. - -raylib started as a weekend project and after three months of hard work, **raylib 1.0 was published on November 2013**. - -Enjoy it. - -notes on raylib 1.1 -------------------- - -On April 2014, after 6 month of first raylib release, raylib 1.1 has been released. This new version presents a complete internal redesign of the library to support OpenGL 1.1, OpenGL 3.3+ and OpenGL ES 2.0. - - - A new module named [rlgl](https://github.com/raysan5/raylib/blob/master/src/rlgl.h) has been added to the library. This new module translates raylib-OpenGL-style immediate mode functions (i.e. rlVertex3f(), rlBegin(), ...) to different versions of OpenGL (1.1, 3.3+, ES2), selectable by one define. - - - [rlgl](https://github.com/raysan5/raylib/blob/master/src/rlgl.h) also comes with a second new module named [raymath](https://github.com/raysan5/raylib/blob/master/src/raymath.h), which includes a bunch of useful functions for 3d-math with vectors, matrices and quaternions. - -Some other big changes of this new version have been the support for OGG files loading and stream playing, and the support of DDS texture files (compressed and uncompressed) along with mipmaps support. - -Lots of code changes and lot of testing have concluded in this amazing new raylib 1.1. - -notes on raylib 1.2 -------------------- - -On September 2014, after 5 month of raylib 1.1 release, it comes raylib 1.2. Again, this version presents a complete internal redesign of [core](https://github.com/raysan5/raylib/blob/master/src/core.c) module to support two new platforms: [Android](http://www.android.com/) and [Raspberry Pi](http://www.raspberrypi.org/). - -It's been some month of really hard work to accomodate raylib to those new platforms while keeping it easy for the users. On Android, raylib manages internally the activity cicle, as well as the inputs; on Raspberry Pi, a complete raw input system has been written from scratch. - - - A new display initialization system has been created to support multiple resolutions, adding black bars if required; user only defines desired screen size and it gets properly displayed. - - - Now raylib can easily deploy games to Android devices and Raspberry Pi (console mode). - -Lots of code changes and lot of testing have concluded in this amazing new raylib 1.2. - -In December 2014, new raylib 1.2.2 was published with support to compile directly for web (html5) using [emscripten](http://kripken.github.io/emscripten-site/) and [asm.js](http://asmjs.org/). - -notes on raylib 1.3 -------------------- - -On September 2015, after 1 year of raylib 1.2 release, arrives raylib 1.3. This version adds shaders functionality, improves tremendously textures module and also provides some new modules (camera system, gestures system, immediate-mode gui). - - - Shaders support is the biggest addition to raylib 1.3, with support for easy shaders loading and use. Loaded shaders can be attached to 3d models or used as fullscreen postrocessing effects. A bunch of postprocessing shaders are also included in this release, check raylib/shaders folder. - - - Textures module has grown to support most of the internal texture formats available in OpenGL (RGB565, RGB888, RGBA5551, RGBA4444, etc.), including compressed texture formats (DXT, ETC1, ETC2, ASTC, PVRT); raylib 1.3 can load .dds, .pkm, .ktx, .astc and .pvr files. - - - A brand new [camera](https://github.com/raysan5/raylib/blob/master/src/camera.c) module offers to the user multiple preconfigured ready-to-use camera systems (free camera, 1st person, 3rd person). Camera modes are very easy to use, just check examples: [core_3d_camera_free.c](https://github.com/raysan5/raylib/blob/master/examples/core_3d_camera_free.c) and [core_3d_camera_first_person.c](https://github.com/raysan5/raylib/blob/master/examples/core_3d_camera_first_person.c). - - - New [gestures](https://github.com/raysan5/raylib/blob/master/src/gestures.h) module simplifies gestures detection on Android and HTML5 programs. - - - [raygui](https://github.com/raysan5/raylib/blob/master/src/raygui.h), the new immediate-mode GUI module offers a set of functions to create simple user interfaces, primary intended for tools development. It's still in experimental state but already fully functional. - -Most of the examples have been completely rewritten and +10 new examples have been added to show the new raylib features. - -Lots of code changes and lot of testing have concluded in this amazing new raylib 1.3. - -notes on raylib 1.4 -------------------- - -On February 2016, after 4 months of raylib 1.3 release, it comes raylib 1.4. For this new version, lots of parts of the library have been reviewed, lots of bugs have been solved and some interesting features have been added. - - - First big addition is a set of [Image manipulation functions](https://github.com/raysan5/raylib/blob/master/src/raylib.h#L673) have been added to crop, resize, colorize, flip, dither and even draw image-to-image or text-to-image. Now a basic image processing can be done before converting the image to texture for usage. - - - SpriteFonts system has been improved, adding support for AngelCode fonts (.fnt) and TrueType Fonts (using [stb_truetype](https://github.com/nothings/stb/blob/master/stb_truetype.h) helper library). Now raylib can read standard .fnt font data and also generate at loading a SpriteFont from a TTF file. - - - New [physac](https://github.com/raysan5/raylib/blob/master/src/physac.h) physics module for basic 2D physics support. Still in development but already functional. Module comes with some usage examples for basic jump and level interaction and also force-based physic movements. - - - [raymath](https://github.com/raysan5/raylib/blob/master/src/raymath.h) module has been reviewed; some bugs have been solved and the module has been converted to a header-only file for easier portability, optionally, functions can also be used as inline. - - - [gestures](https://github.com/raysan5/raylib/blob/master/src/gestures.c) module has redesigned and simplified, now it can process touch events from any source, including mouse. This way, gestures system can be used on any platform providing an unified way to work with inputs and allowing the user to create multiplatform games with only one source code. - - - Raspberry Pi input system has been redesigned to better read raw inputs using generic Linux event handlers (keyboard:`stdin`, mouse:`/dev/input/mouse0`, gamepad:`/dev/input/js0`). Gamepad support has also been added (experimental). - -Other important improvements are the functional raycast system for 3D picking, including some ray collision-detection functions, -and the addition of two simple functions for persistent data storage. Now raylib user can save and load game data in a file (only some platforms supported). A simple [easings](https://github.com/raysan5/raylib/blob/master/src/easings.h) module has also been added for values animation. - -Up to 8 new code examples have been added to show the new raylib features and +10 complete game samples have been provided to learn -how to create some classic games like Arkanoid, Asteroids, Missile Commander, Snake or Tetris. - -Lots of code changes and lots of hours of hard work have concluded in this amazing new raylib 1.4. - -notes on raylib 1.5 -------------------- - -On July 2016, after 5 months of raylib 1.4 release, arrives raylib 1.5. This new version is the biggest boost of the library until now, lots of parts of the library have been redesigned, lots of bugs have been solved and some **AMAZING** new features have been added. - - - VR support: raylib supports **Oculus Rift CV1**, one of the most anticipated VR devices in the market. Additionally, raylib supports simulated VR stereo rendering, independent of the VR device; it means, raylib can generate stereo renders with custom head-mounted-display device parameteres, that way, any VR device in the market can be **simulated in any platform** just configuring device parameters (and consequently, lens distortion). To enable VR is [extremely easy](https://github.com/raysan5/raylib/blob/master/examples/core_oculus_rift.c). - - - New materials system: now raylib supports standard material properties for 3D models, including diffuse-ambient-specular colors and diffuse-normal-specular textures. Just assign values to standard material and everything is processed internally. - - - New lighting system: added support for up to 8 configurable lights and 3 light types: **point**, **directional** and **spot** lights. Just create a light, configure its parameters and raylib manages render internally for every 3d object using standard material. - - - Complete gamepad support on Raspberry Pi: Gamepad system has been completely redesigned. Now multiple gamepads can be easily configured and used; gamepad data is read and processed in raw mode in a second thread. - - - Redesigned physics module: [physac](https://github.com/raysan5/raylib/blob/master/src/physac.h) module has been converted to header only and usage [has been simplified](https://github.com/raysan5/raylib/blob/master/examples/physics_basic_rigidbody.c). Performance has also been singnificantly improved, now physic objects are managed internally in a second thread. - - - Audio chiptunese support and mixing channels: Added support for module audio music (.xm, .mod) loading and playing. Multiple mixing channels are now also supported. All this features thanks to the amazing work of @kd7tck. - -Other additions include a [2D camera system](https://github.com/raysan5/raylib/blob/master/examples/core_2d_camera.c), render textures for offline render (and most comprehensive [postprocessing](https://github.com/raysan5/raylib/blob/master/examples/shaders_postprocessing.c)) or support for legacy OpenGL 2.1 on desktop platforms. - -This new version is so massive that is difficult to list all the improvements, most of raylib modules have been reviewed and [rlgl](https://github.com/raysan5/raylib/blob/master/src/rlgl.c) module has been completely redesigned to accomodate to new material-lighting systems and stereo rendering. You can check [CHANGELOG](https://github.com/raysan5/raylib/blob/master/CHANGELOG) file for a more detailed list of changes. - -Up to 8 new code examples have been added to show the new raylib features and also some samples to show the usage of [rlgl](https://github.com/raysan5/raylib/blob/master/examples/rlgl_standalone.c) and [audio](https://github.com/raysan5/raylib/blob/master/examples/audio_standalone.c) raylib modules as standalone libraries. - -Lots of code changes (+400 commits) and lots of hours of hard work have concluded in this amazing new raylib 1.5. - -notes on raylib 1.6 -------------------- - -On November 2016, only 4 months after raylib 1.5, arrives raylib 1.6. This new version represents another big review of the library and includes some interesting additions. This version conmmemorates raylib 3rd anniversary (raylib 1.0 was published on November 2013) and it is a stepping stone for raylib future. raylib roadmap has been reviewed and redefined to focus on its primary objective: create a simple and easy-to-use library to learn videogames programming. Some of the new features: - - - Complete [raylib Lua binding](https://github.com/raysan5/raylib-lua). All raylib functions plus the +60 code examples have been ported to Lua, now Lua users can enjoy coding videogames in Lua while using all the internal power of raylib. This addition also open the doors to Lua scripting support for a future raylib-based engine, being able to move game logic (Init, Update, Draw, De-Init) to Lua scripts while keep using raylib functionality. - - - Completely redesigned [audio module](https://github.com/raysan5/raylib/blob/master/src/raudio.c). Based on the new direction taken in raylib 1.5, it has been further improved and more functionality added (+20 new functions) to allow raw audio processing and streaming. [FLAC file format support](https://github.com/raysan5/raylib/blob/master/src/external/dr_flac.h) has also been added. In the same line, [OpenAL Soft](https://github.com/kcat/openal-soft) backend is now provided as a static library in Windows to allow static linking and get ride of OpenAL32.dll. Now raylib Windows games are completey self-contained, no external libraries required any more! - - - [Physac](https://github.com/victorfisac/Physac) module has been moved to its own repository and it has been improved A LOT, actually, library has been completely rewritten from scratch by [@victorfisac](https://github.com/victorfisac), multiple samples have been added together with countless new features to match current standard 2D physic libraries. Results are amazing! - - - Camera and gestures modules have been reviewed, highly simplified and ported to single-file header-only libraries for easier portability and usage flexibility. Consequently, camera system usage has been simplified in all examples. - - - Improved Gamepad support on Windows and Raspberry Pi with the addition of new functions for custom gamepad configurations but supporting by default PS3 and Xbox-based gamepads. - - - Improved textures and text functionality, adding new functions for texture filtering control and better TTF/AngelCode fonts loading and generation support. - -Build system improvement. Added support for raylib dynamic library generation (raylib.dll) for users that prefer dynamic library linking. Also thinking on advance users, it has been added pre-configured [Visual Studio C++ 2015 solution](https://github.com/raysan5/raylib/tree/master/project/vs2015) with raylib project and C/C++ examples for users that prefer that professional IDE and compiler. - -New examples, new functions, complete code-base review, multiple bugs corrected... this is raylib 1.6. Enjoy making games. - -notes on raylib 1.7 -------------------- - -On May 2017, around 6 month after raylib 1.6, comes another raylib instalment, raylib 1.7. This time library has been improved a lot in terms of consistency and cleanness. As stated in [this patreon article](https://www.patreon.com/posts/raylib-future-7501034), this new raylib version has focused efforts in becoming more simple and easy-to-use to learn videogames programming. Some highlights of this new version are: - - - More than 30 new functions added to the library, functions to control Window, utils to work with filenames and extensions, functions to draw lines with custom thick, mesh loading, functions for 3d ray collisions detailed detection, funtions for VR simulation and much more... Just check [CHANGELOG](CHANGELOG) for a detailed list of additions! - - - Support of [configuration flags](https://github.com/raysan5/raylib/issues/200) on every raylib module. Advance users can customize raylib just choosing desired features, defining some configuration flags on modules compilation. That way users can control library size and available functionality. - - - Improved [build system](https://github.com/raysan5/raylib/blob/master/src/Makefile) for all supported platforms (Windows, Linux, OSX, RPI, Android, HTML5) with a unique Makefile to compile sources. Added support for Android compilation with a custom standalone toolchain and also multiple build compliation flags. - - - New [examples](http://www.raylib.com/examples.html) and [sample games](http://www.raylib.com/games.html) added. All samples material has been reviewed, removing useless examples and adding more comprehensive ones; all material has been ported to latest raylib version and tested in multiple platforms. Examples folder structure has been improved and also build systems. - - - Improved library consistency and organization in general. Functions and parameters have been renamed, some parts of the library have been cleaned and simplyfied, some functions has been moved to examples (lighting, Oculus Rift CV1 support) towards a more generic library implementation. Lots of hours have been invested in this process... - -Some other features: Gamepad support on HTML5, RPI touch screen support, 32bit audio support, frames timing improvements, public log system, rres file format support, automatic GIF recording... - -And here it is another version of **raylib, a simple and easy-to-use library to enjoy videogames programming**. Enjoy it. - -notes on raylib 1.8 -------------------- - -October 2017, around 5 months after latest raylib version, another release is published: raylib 1.8. Again, several modules of the library have been reviewed and some new functionality added. Main changes of this new release are: - - - [Procedural image generation](https://github.com/raysan5/raylib/blob/master/examples/textures/textures_image_generation.c) function, a set of new functions have been added to generate gradients, checked, noise and cellular images from scratch. Image generation could be useful for certain textures or learning pourpouses. - - - [Parametric mesh generation](https://github.com/raysan5/raylib/blob/master/examples/models/models_mesh_generation.c) functions, create 3d meshes from scratch just defining a set of parameters, meshes like cube, sphere, cylinder, torus, knot and more can be very useful for prototyping or for lighting and texture testing. - - - PBR Materials support, a completely redesigned shaders and material system allows advance materials definition and usage, with fully customizable shaders. Some new functions have been added to generate the environment textures required for PBR shading and a a new complete [PBR material example](https://github.com/raysan5/raylib/blob/master/examples/models/models_material_pbr.c) is also provided for reference. - - - Custom Android APK build pipeline with [simple Makefile](https://github.com/raysan5/raylib/blob/master/templates/simple_game/Makefile). Actually, full code building mechanism based on plain Makefile has been completely reviewed and Android building has been added for sources and also for examples and templates building into final APK package. This way, raylib Android building has been greatly simplified and integrated seamlessly into standard build scripts. - - - [rlgl](https://github.com/raysan5/raylib/blob/master/src/rlgl.h) module has been completely reviewed and most of the functions renamed for consistency. This way, standalone usage of rlgl is promoted, with a [complete example provided](https://github.com/raysan5/raylib/blob/master/examples/others/rlgl_standalone.c). rlgl offers a pseudo-OpenGL 1.1 immediate-mode programming-style layer, with backends to multiple OpenGL versions. - - - [raymath](https://github.com/raysan5/raylib/blob/master/src/raymath.h) library has been also reviewed to align with other advance math libraries like [GLM](https://github.com/g-truc/glm). Matrix math has been improved and simplified, some new Quaternion functions have been added and Vector3 functions have been renamed all around the library for consistency with new Vector2 functionality. - -Additionally, as always, examples and templates have been reviewed to work with new version (some new examples have been added), all external libraries have been updated to latest stable version and latest Notepad++ and MinGW have been configured to work with new raylib. For a full list of changes, just check [CHANGELOG](CHANGELOG). - -New installer provided, web updated, examples re-builded, documentation reviewed... **new raylib 1.8 published**. Enjoy coding games. - -notes on raylib 2.0 -------------------- - -It's been 9 month since last raylib version was published, a lots of things have changed since then... This new raylib version represents an inflexion point in the development of the library and so, we jump to a new major version... Here it is the result of almost **5 years and thousands of hours of hard work**... here it is... **raylib 2.0** - -In **raylib 2.0** the full API has been carefully reviewed for better consistency, some new functionality has been added and the overall raylib experience has been greatly improved... The key features of new version are: - - - **Complete removal of external dependencies.** Finally, raylib does not require external libraries to be installed and linked along with raylib, all required libraries are contained and compiled within raylib. Obviously some external libraries are required but only the strictly platform-dependant ones, the ones that come installed with the OS. So, raylib becomes a self-contained platform-independent games development library. - - - **Full redesign of audio module to use the amazing miniaudio library**, along with external dependencies removal, OpenAL library has been replaced by [miniaudio](https://github.com/dr-soft/miniaudio), this brand new library offers automatic dynamic linking with default OS audio systems. Undoubtly, the perfect low-level companion for raylib audio module! - - - **Support for continuous integration building*** through AppVeyor and Travis CI. Consequently, raylib GitHub develop branch has been removed, simplyfing the code-base to a single master branch, always stable. Every time a new commit is deployed, library is compiled for **up-to 12 different configurations**, including multiple platforms, 32bit/64bit and multiple compiler options! All those binaries are automatically attached to any new release! - - - **More platforms supported and tested**, including BSD family (FreeBSD, openBSD, NetBSD, DragonFly) and Linux-based family platforms (openSUSE, Debian, Ubuntu, Arch, NixOS...). raylib has already been added to some package managers! Oh, and last but not less important, **Android 64bit** is already supported by raylib! - - - **Support for TCC compiler!** Thanks to the lack of external dependencies, raylib can now be easily compiled with a **minimal toolchain**, like the one provide by Tiny C Compiler. It opens the door to an amazing future, allowing, for example, static linkage of libtcc for **runtime compilation of raylib-based code**... and the library itself if required! Moreover, TCC is blazing fast, it can compile all raylib in a couple of seconds! - - - Refactored all raylib configuration #defines into a **centralized `config.h` header**, with more than **40 possible configuration options** to compile a totally customizable raylib version including only desired options like supported file-formats or specific functionality support. It allows generating a trully ligth-weight version of the library if desired! - -A part of that, lots of new features, like a brand **new font rendering and packaging system** for TTF fonts with **SDF support** (thanks to the amazing STB headers), new functions for **CPU image data manipulation**, new orthographic 3d camera mode, a complete review of `raymath.h` single-file header-only library for better consistency and performance, new examples and way, [way more](https://github.com/raysan5/raylib/blob/master/CHANGELOG). - -Probably by now, **raylib 2.0 is the simplest and easiest-to-use library to enjoy (and learn) videogames programming**... but, undoubtly its development has exceeded any initial objective; raylib has become a simple and easy-to-use trully multiplatform portable standalone media library with thousands of possibilities... and that's just the beginning! - -notes on raylib 2.5 -------------------- - -After almost one years since latest raylib installment, here it is **raylib 2.5**. A lot of work has been put on this new version and consequently I decided to bump versioning several digits. The complete list of changes and additions is humungous, details can be found in the [CHANGELOG](CHANGELOG), and here it is a short recap with the highlight improvements. - - - New **window management and file system functions** to query monitor information, deal with clipboard, check directory files info and even launch a URL with default system web browser. Experimental **High-DPI monitor support** has also been added through a compile flag. - - - **Redesigned Gamepad mechanism**, now generic for all platforms and gamepads, no more specific gamepad configurations. -**Redesigned UWP input system**, now raylib supports UWP seamlessly, previous implementation required a custom input system implemented in user code. - - - `rlgl` module has been redesigned to **support a unique buffer for shapes drawing batching**, including LINES, TRIANGLES, QUADS in the same indexed buffer, also added support for multi-buffering if required. Additionally, `rlPushMatrix()`/`rlPopMatrix()` functionality has been reviewed to behave exactly like OpenGL 1.1, `models_rlgl_solar_system` example has been added to illustrate this behaviour. - - - **VR simulator** has been reviewed to **allow custom configuration of Head-Mounted-Device parameters and distortion shader**, `core_vr_simulator` has been properly adapted to showcase this new functionality, now the VR simulator is a generic configurable stereo rendering system that allows any VR device simulation with just a few lines of code or even dynamic tweaking of HMD parameters. - - - Support for **Unicode text drawing**; now raylib processes UTF8 strings on drawing, supporting Unicode codepoints, allowing rendering mostly any existent language (as long as the font with the glyphs is provided). An amazing example showing this feature has also been added: `text_unicode`. - - - Brand **new text management API**, with the addition of multiple functions to deal with string data, including functionality like replace, insert, join, split, append, to uppercase, to lower... Note that most of those functions are intended for text management on rendering, using pre-loaded internal buffers, avoiding new memory allocation that user should free manually. - - - Multiple **new shapes and textures drawing functions** to support rings (`DrawRing()`, `DrawRingLines()`), circle sectors (`DrawCircleSector()`, `DrawCircleSectorLines()`), rounded rectangles (`DrawRectangleRounded()`, `DrawRectangleRoundedLines()`) and also n-patch textures (`DrawTextureNPatch()`), detailed examples have been added to illustrate all this new functionality. - - - Experimental **cubemap support**, to automatically load multiple cubemap layouts (`LoadTextureCubemap()`). It required some internal `rlgl` redesign to allow cubemap textures. - - - **Skeletal animation support for 3d models**, this addition implied a redesign of `Model` data structure to accomodate multiple mesh/multiple materials support and bones information. Multiple models functions have been reviewed and added on this process, also **glTF models loading support** has been added. - -This is a just a brief list with some of the changes of the new **raylib 2.5** but there is way more, about **70 new functions** have been added and several subsystems have been redesigned. More than **30 new examples** have been created to show the new functionalities and better illustrate already available ones. - -It has been a long year of hard work to make raylib a solid technology to develop new products over it. - -notes on raylib 3.0 -------------------- - -After **10 months of intense development**, new raylib version is ready. Despite primary intended as a minor release, the [CHANGELIST](CHANGELOG) has grown so big and the library has changed so much internally that it finally became a major release. Library **internal ABI** has reveived a big redesign and review, targeting portability, integration with other platforms and making it a perfect option for other progamming [language bindings](BINDINGS.md). - - - All **global variables** from the multiple raylib modules have been moved to a **global context state**, it has several benefits, first, better code readability with more comprehensive variables naming and categorization (organized by types, i.e. `CORE.Window.display.width`, `CORE.Input.Keyboard.currentKeyState` or `RLGL.State.modelview`). Second, it allows better memory management to load global context state dynamically when required (not at the moment), making it easy to implement a **hot-reloading mechanism** if desired. - - - All **memory allocations** on raylib and its dependencies now use `RL_MALLOC`, `RL_FREE` and similar macros. Now users can easely hook their own memory allocations mechanism if desired, having more control over memory allocated internally by the library. Additionally, it makes it easier to port the library to embedded devices where memory control is critical. For more info check raylib issue #1074. - - - All **I/O file accesses** from raylib are being moved to **memory data access**, now all I/O file access is centralized into just four functions: `LoadFileData()`, `SaveFileData()`, `LoadFileText()`, `SaveFileText()`. Users can just update those functions to any I/O file system. This change makes it easier to integrate raylib with **Virtual File Systems** or custom I/O file implementations. - - - All **raylib data structures** have been reviewed and optimized for pass-by-value usage. One of raylib distinctive design decisions is that most of its functions receive and return data by value. This design makes raylib really simple for newcomers, avoiding pointers and allowing complete access to all structures data in a simple way. The downside is that data is copied on stack every function call and that copy could be costly so, all raylib data structures have been optimized to **stay under 64 bytes** for fast copy and retrieve. - - - All **raylib tracelog messages** have been reviewd and categorized for a more comprehensive output information when developing raylib applications, now all display, input, timer, platform, auxiliar libraries, file-accesses, data loading/unloading issues are properly reported with more detailed and visual messages. - - - `raudio` module has been internally reviewed to accomodate the new `Music` structure (converted from previous pointer format) and the module has been adapted to the **highly improved** [`miniaudio v0.10`](https://github.com/dr-soft/miniaudio). - - - `text` module reviewed to **improve fonts generation** and text management functions, `Font` structure has been redesigned to better accomodate characters data, decoupling individual characters as `Image` glyphs from the font atlas parameters. Several improvements have been made to better support Unicode strings with UTF-8 encoding. - - - **Multiple new examples added** (most of them contributed by raylib users) and all examples reviewed for correct execution on most of the supported platforms, specially Web and Raspberry Pi. A detailed categorized table has been created on github for easy examples navigation and code access. - - - New **GitHub Actions CI** system has been implemented for Windows, Linux and macOS code and examples compilation on every new commit or PR to make sure library keeps stable and usable with no breaking bugs. - -Note that only key changes are listed here but there is way more! About **30 new functions**, multiple functions reviewed, bindings to [+40 programming languages](https://github.com/raysan5/raylib/blob/master/BINDINGS.md) and great samples/demos/tutorials [created by the community](https://discord.gg/VkzNHUE), including raylib integration with [Spine](https://github.com/WEREMSOFT/spine-raylib-runtimes), [Unity](https://unitycoder.com/blog/2019/12/09/using-raylib-dll-in-unity/), [Tiled](https://github.com/OnACoffeeBreak/raylib_tiled_import_with_tmx), [Nuklear](http://bedroomcoders.co.uk/implementing-a-3d-gui-with-raylib/), [enet](https://github.com/nxrighthere/NetDynamics) and [more](https://github.com/raysan5/raylib/issues/1079)! - -It has been **10 months of improvements** to create the best raylib ever. - -Welcome to **raylib 3.0**. diff --git a/libs/raylib/LICENSE b/libs/raylib/LICENSE deleted file mode 100644 index a0c604d..0000000 --- a/libs/raylib/LICENSE +++ /dev/null @@ -1,16 +0,0 @@ -Copyright (c) 2013-2020 Ramon Santamaria (@raysan5) - -This software is provided "as-is", without any express or implied warranty.

Returns false if the passed-in - * element_size is too small, or if the accessor is sparse. - * - * `cgltf_accessor_read_index` is similar to its floating-point counterpart, but it returns size_t - * and only works with single-component data types. - * - * `cgltf_result cgltf_copy_extras_json(const cgltf_data*, const cgltf_extras*, - * char* dest, cgltf_size* dest_size)` allows users to retrieve the "extras" data that - * can be attached to many glTF objects (which can be arbitrary JSON data). The - * `cgltf_extras` struct stores the offsets of the start and end of the extras JSON data - * as it appears in the complete glTF JSON data. This function copies the extras data - * into the provided buffer. If `dest` is NULL, the length of the data is written into - * `dest_size`. You can then parse this data using your own JSON parser - * or, if you've included the cgltf implementation using the integrated JSMN JSON parser. - */ -#ifndef CGLTF_H_INCLUDED__ -#define CGLTF_H_INCLUDED__ - -#include - -#ifdef __cplusplus -extern "C" { -#endif - -typedef size_t cgltf_size;

To use it, do something like the following in one .c file. - #define DR_FLAC_IMPLEMENTATION - #include "dr_flac.h" - -You can then #include this file in other parts of the program as you would with any other header file. To decode audio data, -do something like the following: - - drflac* pFlac = drflac_open_file("MySong.flac"); - if (pFlac == NULL) { - // Failed to open FLAC file - } - - drflac_int32* pSamples = malloc(pFlac->totalPCMFrameCount * pFlac->channels * sizeof(drflac_int32)); - drflac_uint64 numberOfInterleavedSamplesActuallyRead = drflac_read_pcm_frames_s32(pFlac, pFlac->totalPCMFrameCount, pSamples); - -The drflac object represents the decoder. It is a transparent type so all the information you need, such as the number of -channels and the bits per sample, should be directly accessible - just make sure you don't change their values. Samples are -always output as interleaved signed 32-bit PCM. In the example above a native FLAC stream was opened, however dr_flac has -seamless support for Ogg encapsulated FLAC streams as well. - -You do not need to decode the entire stream in one go - you just specify how many samples you'd like at any given time and -the decoder will give you as many samples as it can, up to the amount requested. Later on when you need the next batch of -samples, just call it again. Example: - - while (drflac_read_pcm_frames_s32(pFlac, chunkSizeInPCMFrames, pChunkSamples) > 0) { - do_something(); - } - -You can seek to a specific sample with drflac_seek_to_sample(). The given sample is based on interleaving. So for example, -if you were to seek to the sample at index 0 in a stereo stream, you'll be seeking to the first sample of the left channel. -The sample at index 1 will be the first sample of the right channel. The sample at index 2 will be the second sample of the -left channel, etc. - - -If you just want to quickly decode an entire FLAC file in one go you can do something like this: - - unsigned int channels; - unsigned int sampleRate; - drflac_uint64 totalPCMFrameCount; - drflac_int32* pSampleData = drflac_open_file_and_read_pcm_frames_s32("MySong.flac", &channels, &sampleRate, &totalPCMFrameCount); - if (pSampleData == NULL) { - // Failed to open and decode FLAC file. - } - - ... - - drflac_free(pSampleData); - - -You can read samples as signed 16-bit integer and 32-bit floating-point PCM with the *_s16() and *_f32() family of APIs -respectively, but note that these should be considered lossy. - - -If you need access to metadata (album art, etc.), use drflac_open_with_metadata(), drflac_open_file_with_metdata() or -drflac_open_memory_with_metadata(). The rationale for keeping these APIs separate is that they're slightly slower than the -normal versions and also just a little bit harder to use. - -dr_flac reports metadata to the application through the use of a callback, and every metadata block is reported before -drflac_open_with_metdata() returns. - - -The main opening APIs (drflac_open(), etc.) will fail if the header is not present. The presents a problem in certain -scenarios such as broadcast style streams like internet radio where the header may not be present because the user has -started playback mid-stream. To handle this, use the relaxed APIs: drflac_open_relaxed() and drflac_open_with_metadata_relaxed(). - -It is not recommended to use these APIs for file based streams because a missing header would usually indicate a -corrupted or perverse file. In addition, these APIs can take a long time to initialize because they may need to spend -a lot of time finding the first frame. - - - -OPTIONS -======= -#define these options before including this file. - -#define DR_FLAC_NO_STDIO - Disable drflac_open_file() and family. - -#define DR_FLAC_NO_OGG - Disables support for Ogg/FLAC streams. - -#define DR_FLAC_BUFFER_SIZE - Defines the size of the internal buffer to store data from onRead(). This buffer is used to reduce the number of calls - back to the client for more data. Larger values means more memory, but better performance.

See the bottom of this file for -differences between minimp3 and dr_mp3. -*/ - -/* -USAGE -===== -dr_mp3 is a single-file library. To use it, do something like the following in one .c file. - #define DR_MP3_IMPLEMENTATION - #include "dr_mp3.h" - -You can then #include this file in other parts of the program as you would with any other header file. To decode audio data, -do something like the following: - - drmp3 mp3; - if (!drmp3_init_file(&mp3, "MySong.mp3", NULL)) { - // Failed to open file - } - - ... - - drmp3_uint64 framesRead = drmp3_read_pcm_frames_f32(pMP3, framesToRead, pFrames); - -The drmp3 object is transparent so you can get access to the channel count and sample rate like so: - - drmp3_uint32 channels = mp3.channels; - drmp3_uint32 sampleRate = mp3.sampleRate; - -The third parameter of drmp3_init_file() in the example above allows you to control the output channel count and sample rate. It -is a pointer to a drmp3_config object. Setting any of the variables of this object to 0 will cause dr_mp3 to use defaults. - -The example above initializes a decoder from a file, but you can also initialize it from a block of memory and read and seek -callbacks with drmp3_init_memory() and drmp3_init() respectively. - -You do not need to do any annoying memory management when reading PCM frames - this is all managed internally. You can request -any number of PCM frames in each call to drmp3_read_pcm_frames_f32() and it will return as many PCM frames as it can, up to the -requested amount. - -You can also decode an entire file in one go with drmp3_open_and_read_f32(), drmp3_open_memory_and_read_f32() and -drmp3_open_file_and_read_f32(). - - -OPTIONS -======= -#define these options before including this file. - -#define DR_MP3_NO_STDIO - Disable drmp3_init_file(), etc. - -#define DR_MP3_NO_SIMD - Disable SIMD optimizations. -*/ - -#ifndef dr_mp3_h -#define dr_mp3_h - -#ifdef __cplusplus -extern "C" { -#endif - -#include - -#if defined(_MSC_VER) && _MSC_VER < 1600 -typedef signed char drmp3_int8; -typedef unsigned char drmp3_uint8; -typedef signed short drmp3_int16; -typedef unsigned short drmp3_uint16; -typedef signed int drmp3_int32; -typedef unsigned int drmp3_uint32; -typedef signed __int64 drmp3_int64; -typedef unsigned __int64 drmp3_uint64; -#else -#include -typedef int8_t drmp3_int8; -typedef uint8_t drmp3_uint8; -typedef int16_t drmp3_int16; -typedef uint16_t drmp3_uint16; -typedef int32_t drmp3_int32; -typedef uint32_t drmp3_uint32; -typedef int64_t drmp3_int64; -typedef uint64_t drmp3_uint64; -#endif -typedef drmp3_uint8 drmp3_bool8; -typedef drmp3_uint32 drmp3_bool32; -#define DRMP3_TRUE 1 -#define DRMP3_FALSE 0 - -#define DRMP3_MAX_PCM_FRAMES_PER_MP3_FRAME 1152 -#define DRMP3_MAX_SAMPLES_PER_FRAME (DRMP3_MAX_PCM_FRAMES_PER_MP3_FRAME*2) - -#ifdef _MSC_VER -#define DRMP3_INLINE __forceinline -#else -#ifdef __GNUC__ -#define DRMP3_INLINE __inline__ __attribute__((always_inline)) -#else -#define DRMP3_INLINE -#endif -#endif - -/* -Low Level Push API -================== -*/ -typedef struct -{ - int frame_bytes, channels, hz, layer, bitrate_kbps; -} drmp3dec_frame_info; - -typedef struct -{ - float mdct_overlap[2][9*32], qmf_state[15*2*32]; - int reserv, free_format_bytes; - unsigned char header[4], reserv_buf[511]; -} drmp3dec; - -/* Initializes a low level decoder. */ -void drmp3dec_init(drmp3dec *dec); - -/* Reads a frame from a low level decoder. */ -int drmp3dec_decode_frame(drmp3dec *dec, const unsigned char *mp3, int mp3_bytes, void *pcm, drmp3dec_frame_info *info); - -/* Helper for converting between f32 and s16. */ -void drmp3dec_f32_to_s16(const float *in, drmp3_int16 *out, int num_samples); - - - -/* -Main API (Pull API) -=================== -*/ -#ifndef DR_MP3_DEFAULT_CHANNELS -#define DR_MP3_DEFAULT_CHANNELS 2 -#endif -#ifndef DR_MP3_DEFAULT_SAMPLE_RATE -#define DR_MP3_DEFAULT_SAMPLE_RATE 44100 -#endif - -typedef struct drmp3_src drmp3_src; -typedef drmp3_uint64 (* drmp3_src_read_proc)(drmp3_src* pSRC, drmp3_uint64 frameCount, void* pFramesOut, void* pUserData); /* Returns the number of frames that were read. */ - -typedef enum -{ - drmp3_src_algorithm_none, - drmp3_src_algorithm_linear -} drmp3_src_algorithm; - -#define DRMP3_SRC_CACHE_SIZE_IN_FRAMES 512 -typedef struct -{ - drmp3_src* pSRC; - float pCachedFrames[2 * DRMP3_SRC_CACHE_SIZE_IN_FRAMES]; - drmp3_uint32 cachedFrameCount; - drmp3_uint32 iNextFrame; -} drmp3_src_cache; - -typedef struct -{ - drmp3_uint32 sampleRateIn; - drmp3_uint32 sampleRateOut; - drmp3_uint32 channels; - drmp3_src_algorithm algorithm; - drmp3_uint32 cacheSizeInFrames; /* The number of frames to read from the client at a time. */ -} drmp3_src_config; - -struct drmp3_src -{ - drmp3_src_config config; - drmp3_src_read_proc onRead; - void* pUserData; - float bin[256]; - drmp3_src_cache cache; /* <-- For simplifying and optimizing client -> memory reading. */ - union - { - struct - { - double alpha; - drmp3_bool32 isPrevFramesLoaded : 1; - drmp3_bool32 isNextFramesLoaded : 1; - } linear; - } algo; -}; - -typedef enum -{ - drmp3_seek_origin_start, - drmp3_seek_origin_current -} drmp3_seek_origin; - -typedef struct -{ - drmp3_uint64 seekPosInBytes; /* Points to the first byte of an MP3 frame. */ - drmp3_uint64 pcmFrameIndex; /* The index of the PCM frame this seek point targets. */ - drmp3_uint16 mp3FramesToDiscard; /* The number of whole MP3 frames to be discarded before pcmFramesToDiscard. */ - drmp3_uint16 pcmFramesToDiscard; /* The number of leading samples to read and discard.

For example, given a stereo WAV file, previously you would pass 2 to drwav_read_f32() to read one -PCM frame, whereas now you would pass in 1 to drwav_read_pcm_frames_f32(). The old APIs would return the number of samples -read, whereas now it will return the number of PCM frames. Below is a list of APIs that have been deprecated and their -replacements. - - drwav_read() -> drwav_read_pcm_frames() - drwav_read_s16() -> drwav_read_pcm_frames_s16() - drwav_read_f32() -> drwav_read_pcm_frames_f32() - drwav_read_s32() -> drwav_read_pcm_frames_s32() - drwav_seek_to_sample() -> drwav_seek_to_pcm_frame() - drwav_write() -> drwav_write_pcm_frames() - drwav_open_and_read_s16() -> drwav_open_and_read_pcm_frames_s16() - drwav_open_and_read_f32() -> drwav_open_and_read_pcm_frames_f32() - drwav_open_and_read_s32() -> drwav_open_and_read_pcm_frames_s32() - drwav_open_file_and_read_s16() -> drwav_open_file_and_read_pcm_frames_s16() - drwav_open_file_and_read_f32() -> drwav_open_file_and_read_pcm_frames_f32() - drwav_open_file_and_read_s32() -> drwav_open_file_and_read_pcm_frames_s32() - drwav_open_memory_and_read_s16() -> drwav_open_memory_and_read_pcm_frames_s16() - drwav_open_memory_and_read_f32() -> drwav_open_memory_and_read_pcm_frames_f32() - drwav_open_memory_and_read_s32() -> drwav_open_memory_and_read_pcm_frames_s32() - drwav::totalSampleCount -> drwav::totalPCMFrameCount - -Rationale: - 1) Most programs will want to read in multiples of the channel count which demands a per-frame reading API. Per-sample - reading just adds complexity and maintenance costs for no practical benefit. - 2) This is consistent with my other decoders - dr_flac and dr_mp3. - -These APIs will be removed completely in version 0.10.0. You can continue to use drwav_read_raw() if you need per-sample -reading. -*/ - -/* -USAGE -===== -This is a single-file library. To use it, do something like the following in one .c file. - #define DR_WAV_IMPLEMENTATION - #include "dr_wav.h" - -You can then #include this file in other parts of the program as you would with any other header file. Do something -like the following to read audio data: - - drwav wav; - if (!drwav_init_file(&wav, "my_song.wav")) { - // Error opening WAV file. - } - - drwav_int32* pDecodedInterleavedSamples = malloc(wav.totalPCMFrameCount * wav.channels * sizeof(drwav_int32)); - size_t numberOfSamplesActuallyDecoded = drwav_read_pcm_frames_s32(&wav, wav.totalPCMFrameCount, pDecodedInterleavedSamples); - - ... - - drwav_uninit(&wav); - -You can also use drwav_open() to allocate and initialize the loader for you: - - drwav* pWav = drwav_open_file("my_song.wav"); - if (pWav == NULL) { - // Error opening WAV file. - } - - ... - - drwav_close(pWav); - -If you just want to quickly open and read the audio data in a single operation you can do something like this: - - unsigned int channels; - unsigned int sampleRate; - drwav_uint64 totalPCMFrameCount; - float* pSampleData = drwav_open_file_and_read_pcm_frames_f32("my_song.wav", &channels, &sampleRate, &totalPCMFrameCount); - if (pSampleData == NULL) { - // Error opening and reading WAV file. - } - - ... - - drwav_free(pSampleData); - -The examples above use versions of the API that convert the audio data to a consistent format (32-bit signed PCM, in -this case), but you can still output the audio data in its internal format (see notes below for supported formats): - - size_t samplesRead = drwav_read_pcm_frames(&wav, wav.totalPCMFrameCount, pDecodedInterleavedSamples); - -You can also read the raw bytes of audio data, which could be useful if dr_wav does not have native support for -a particular data format: - - size_t bytesRead = drwav_read_raw(&wav, bytesToRead, pRawDataBuffer); - - -dr_wav can also be used to output WAV files. This does not currently support compressed formats. To use this, look at -drwav_open_write(), drwav_open_file_write(), etc. Use drwav_write_pcm_frames() to write samples, or drwav_write_raw() -to write raw data in the "data" chunk. - - drwav_data_format format; - format.container = drwav_container_riff; // <-- drwav_container_riff = normal WAV files, drwav_container_w64 = Sony Wave64. - format.format = DR_WAVE_FORMAT_PCM; // <-- Any of the DR_WAVE_FORMAT_* codes. - format.channels = 2; - format.sampleRate = 44100; - format.bitsPerSample = 16; - drwav* pWav = drwav_open_file_write("data/recording.wav", &format); - - ... - - drwav_uint64 samplesWritten = drwav_write_pcm_frames(pWav, frameCount, pSamples); - - -dr_wav has seamless support the Sony Wave64 format. The decoder will automatically detect it and it should Just Work -without any manual intervention. - - -OPTIONS -======= -#define these options before including this file. - -#define DR_WAV_NO_CONVERSION_API - Disables conversion APIs such as drwav_read_pcm_frames_f32() and drwav_s16_to_f32(). - -#define DR_WAV_NO_STDIO - Disables drwav_open_file(), drwav_open_file_write(), etc. - - - -QUICK NOTES -=========== -- Samples are always interleaved. -- The default read function does not do any data conversion. Use drwav_read_pcm_frames_f32(), drwav_read_pcm_frames_s32() - and drwav_read_pcm_frames_s16() to read and convert audio data to 32-bit floating point, signed 32-bit integer and - signed 16-bit integer samples respectively.

It provides a simple, platform-independent API for -creating windows, contexts and surfaces, reading input, handling events, etc. - -GLFW natively supports Windows, macOS and Linux and other Unix-like systems. On -Linux both X11 and Wayland are supported. - -GLFW is licensed under the [zlib/libpng -license](http://www.glfw.org/license.html). - -You can [download](http://www.glfw.org/download.html) the latest stable release -as source or Windows binaries, or fetch the `latest` branch from GitHub. Each -release starting with 3.0 also has a corresponding [annotated -tag](https://github.com/glfw/glfw/releases) with source and binary archives. - -The [documentation](http://www.glfw.org/docs/latest/) is available online and is -included in all source and binary archives. See the [release -notes](https://www.glfw.org/docs/latest/news.html) for new features, caveats and -deprecations in the latest release. For more details see the [version -history](http://www.glfw.org/changelog.html). - -The `master` branch is the stable integration branch and _should_ always compile -and run on all supported platforms, although details of newly added features may -change until they have been included in a release. New features and many bug -fixes live in [other branches](https://github.com/glfw/glfw/branches/all) until -they are stable enough to merge. - -If you are new to GLFW, you may find the -[tutorial](http://www.glfw.org/docs/latest/quick.html) for GLFW 3 useful. If -you have used GLFW 2 in the past, there is a [transition -guide](http://www.glfw.org/docs/latest/moving.html) for moving to the GLFW -3 API. - - -## Compiling GLFW - -GLFW itself requires only the headers and libraries for your OS and window -system. It does not need the headers for any context creation API (WGL, GLX, -EGL, NSGL, OSMesa) or rendering API (OpenGL, OpenGL ES, Vulkan) to enable -support for them. - -GLFW supports compilation on Windows with Visual C++ 2010 and later, MinGW and -MinGW-w64, on macOS with Clang and on Linux and other Unix-like systems with GCC -and Clang. It will likely compile in other environments as well, but this is -not regularly tested. - -There are [pre-compiled Windows binaries](http://www.glfw.org/download.html) -available for all supported compilers. - -See the [compilation guide](http://www.glfw.org/docs/latest/compile.html) for -more information about how to compile GLFW yourself. - - -## Using GLFW - -See the [documentation](http://www.glfw.org/docs/latest/) for tutorials, guides -and the API reference. - - -## Contributing to GLFW - -See the [contribution -guide](https://github.com/glfw/glfw/blob/master/docs/CONTRIBUTING.md) for -more information. - - -## System requirements - -GLFW supports Windows XP and later and macOS 10.8 and later. Linux and other -Unix-like systems running the X Window System are supported even without -a desktop environment or modern extensions, although some features require -a running window or clipboard manager. The OSMesa backend requires Mesa 6.3. - -See the [compatibility guide](http://www.glfw.org/docs/latest/compat.html) -in the documentation for more information. - - -## Dependencies - -GLFW itself needs only CMake 3.1 or later and the headers and libraries for your -OS and window system. - -The (experimental) Wayland backend also depends on the `extra-cmake-modules` -package, which is used to generate Wayland protocol headers. - -The examples and test programs depend on a number of tiny libraries. These are -located in the `deps/` directory. - - - [getopt\_port](https://github.com/kimgr/getopt_port/) for examples - with command-line options - - [TinyCThread](https://github.com/tinycthread/tinycthread) for threaded - examples - - [glad2](https://github.com/Dav1dde/glad) for loading OpenGL and Vulkan - functions - - [linmath.h](https://github.com/datenwolf/linmath.h) for linear algebra in - examples - - [Nuklear](https://github.com/vurtun/nuklear) for test and example UI - - [stb\_image\_write](https://github.com/nothings/stb) for writing images to disk - -The documentation is generated with [Doxygen](http://doxygen.org/) if CMake can -find that tool. - - -## Reporting bugs - -Bugs are reported to our [issue tracker](https://github.com/glfw/glfw/issues). -Please check the [contribution -guide](https://github.com/glfw/glfw/blob/master/docs/CONTRIBUTING.md) for -information on what to include when reporting a bug. -

Data conversion is performed internally to convert -audio data between the format requested when initializing the `ma_device` object and the format of the internal device used by the backend. The same applies -to the `ma_decoder` object. The previous design has several design flaws and missing features which necessitated a complete redesign. - - -Changes to Data Conversion --------------------------- -The previous data conversion system used callbacks to deliver input data for conversion. This design works well in some specific situations, but in other -situations it has some major readability and maintenance issues. The decision was made to replace this with a more iterative approach where you just pass in a -pointer to the input data directly rather than dealing with a callback. - -The following are the data conversion APIs that have been removed and their replacements: - - - ma_format_converter -> ma_convert_pcm_frames_format() - - ma_channel_router -> ma_channel_converter - - ma_src -> ma_resampler - - ma_pcm_converter -> ma_data_converter - -The previous conversion APIs accepted a callback in their configs. There are no longer any callbacks to deal with. Instead you just pass the data into the -`*_process_pcm_frames()` function as a pointer to a buffer. - -The simplest aspect of data conversion is sample format conversion. To convert between two formats, just call `ma_convert_pcm_frames_format()`. Channel -conversion is also simple which you can do with `ma_channel_router` via `ma_channel_router_process_pcm_frames(). - -Resampling is more complicated because the number of output frames that are processed is different to the number of input frames that are consumed. When you -call `ma_resampler_process_pcm_frames()` you need to pass in the number of input frames available for processing and the number of output frames you want to -output. Upon returning they will receive the number of input frames that were consumed and the number of output frames that were generated. - -The `ma_data_converter` API is a wrapper around format, channel and sample rate conversion and handles all of the data conversion you'll need which probably -makes it the best option if you need to do data conversion. - -In addition to changes to the API design, a few other changes have been made to the data conversion pipeline: - - - The sinc resampler has been removed. This was completely broken and never actually worked properly. - - The linear resampler can now uses low-pass filtering to remove aliasing. The quality of the low-pass filter can be controlled via the resampler config with - the `lpfCount` option, which has a maximum value of MA_MAX_RESAMPLER_LPF_FILTERS. - - Data conversion now supports s16 natively which runs through a fixed point pipeline. Previously everything needed to be converted to floating point before - processing, whereas now both s16 and f32 are natively supported. Other formats still require conversion to either s16 or f32 prior to processing, however - `ma_data_converter` will handle this for you. - - -Custom Memory Allocators ------------------------- -miniaudio has always supported macro level customization for memory allocation via MA_MALLOC, MA_REALLOC and MA_FREE, however some scenarios require more -flexibility by allowing a user data pointer to be passed to the custom allocation routines. Support for this has been added to version 0.10 via the -`ma_allocation_callbacks` structure. Anything making use of heap allocations has been updated to accept this new structure. - -The `ma_context_config` structure has been updated with a new member called `allocationCallbacks`. Leaving this set to it's defaults returned by -`ma_context_config_init()` will cause it to use MA_MALLOC, MA_REALLOC and MA_FREE. Likewise, The `ma_decoder_config` structure has been updated in the same -way, and leaving everything as-is after `ma_decoder_config_init()` will cause it to use the same defaults. - -The following APIs have been updated to take a pointer to a `ma_allocation_callbacks` object. Setting this parameter to NULL will cause it to use defaults. -Otherwise they will use the relevant callback in the structure. - - - ma_malloc() - - ma_realloc() - - ma_free() - - ma_aligned_malloc() - - ma_aligned_free() - - ma_rb_init() / ma_rb_init_ex() - - ma_pcm_rb_init() / ma_pcm_rb_init_ex() - -Note that you can continue to use MA_MALLOC, MA_REALLOC and MA_FREE as per normal. These will continue to be used by default if you do not specify custom -allocation callbacks. - - -Buffer and Period Configuration Changes ---------------------------------------- -The way in which the size of the internal buffer and periods are specified in the device configuration have changed. In previous versions, the config variables -`bufferSizeInFrames` and `bufferSizeInMilliseconds` defined the size of the entire buffer, with the size of a period being the size of this variable divided by -the period count. This became confusing because people would expect the value of `bufferSizeInFrames` or `bufferSizeInMilliseconds` to independantly determine -latency, when in fact it was that value divided by the period count that determined it. These variables have been removed and replaced with new ones called -`periodSizeInFrames` and `periodSizeInMilliseconds`. - -These new configuration variables work in the same way as their predecessors in that if one is set to 0, the other will be used, but the main difference is -that you now set these to you desired latency rather than the size of the entire buffer. The benefit of this is that it's much easier and less confusing to -configure latency. - -The following unused APIs have been removed: - - ma_get_default_buffer_size_in_milliseconds() - ma_get_default_buffer_size_in_frames() - -The following macros have been removed: - - MA_BASE_BUFFER_SIZE_IN_MILLISECONDS_LOW_LATENCY - MA_BASE_BUFFER_SIZE_IN_MILLISECONDS_CONSERVATIVE - - -Other API Changes ------------------ -Other less major API changes have also been made in version 0.10. - -`ma_device_set_stop_callback()` has been removed. You now must set the stop callback via the device config just like the data callback. - -The `ma_sine_wave` API has been replaced with a more general API called `ma_waveform`. This supports generation of different types of waveforms, including -sine, square, triangle and sawtooth. Use `ma_waveform_init()` in place of `ma_sine_wave_init()` to initialize the waveform object. This takes the same -parameters, except an additional `ma_waveform_type` value which you would set to `ma_waveform_type_sine`. Use `ma_waveform_read_pcm_frames()` in place of -`ma_sine_wave_read_f32()` and `ma_sine_wave_read_f32_ex()`. - -`ma_convert_frames()` and `ma_convert_frames_ex()` have been changed. Both of these functions now take a new parameter called `frameCountOut` which specifies -the size of the output buffer in PCM frames. This has been added for safety. In addition to this, the parameters for `ma_convert_frames_ex()` have changed to -take a pointer to a `ma_data_converter_config` object to specify the input and output formats to convert between. This was done to make it make it more -flexible, to prevent the parameter list getting too long, and to prevent API breakage whenever a new conversion property is added. - -`ma_calculate_frame_count_after_src()` has been renamed to `ma_calculate_frame_count_after_resampling()` for consistency with the new `ma_resampler` API. - - -Biquad and Low-Pass Filters ---------------------------- -A generic biquad filter has been added. This is used via the `ma_biquad` API. The biquad filter is used as the basis for the low-pass filter. The biquad filter -supports 32-bit floating point samples which runs on a floating point pipeline and 16-bit signed integer samples which runs on a 32-bit fixed point pipeline. -Both formats use transposed direct form 2. - -The low-pass filter is just a biquad filter. By itself it's a second order low-pass filter, but it can be extended to higher orders by chaining low-pass -filters together. Low-pass filtering is achieved via the `ma_lpf` API. Since the low-pass filter is just a biquad filter, it supports both 32-bit floating -point and 16-bit signed integer formats. - - -Sine, Square, Triangle and Sawtooth Waveforms ---------------------------------------------- -Previously miniaudio supported only sine wave generation. This has now been generalized to support sine, square, triangle and sawtooth waveforms. The old -`ma_sine_wave` API has been removed and replaced with the `ma_waveform` API. Use `ma_waveform_init()` to initialize the waveform. Here you specify tyhe type of -waveform you want to generated. You then read data using `ma_waveform_read_pcm_frames()`. - - -Miscellaneous Changes ---------------------- -Internal functions have all been made static where possible. If you get warnings about unused functions, please submit a bug report. - -The `ma_device` structure is no longer defined as being aligned to MA_SIMD_ALIGNMENT. This resulted in a possible crash when allocating a `ma_device` object on -the heap, but not aligning it to MA_SIMD_ALIGNMENT. This crash would happen due to the compiler seeing the alignment specified on the structure and assuming it -was always aligned as such and thinking it was safe to emit alignment-dependant SIMD instructions. Since miniaudio's philosophy is for things to just work, -this has been removed from all structures. -*/ - - -/* -Introduction -============ -miniaudio is a single file library for audio playback and capture. To use it, do the following in one .c file: - - ```c - #define MINIAUDIO_IMPLEMENTATION - #include "miniaudio.h - ``` - -You can #include miniaudio.h in other parts of the program just like any other header. - -miniaudio uses the concept of a "device" as the abstraction for physical devices. The idea is that you choose a physical device to emit or capture audio from, -and then move data to/from the device when miniaudio tells you to. Data is delivered to and from devices asynchronously via a callback which you specify when -initializing the device. - -When initializing the device you first need to configure it. The device configuration allows you to specify things like the format of the data delivered via -the callback, the size of the internal buffer and the ID of the device you want to emit or capture audio from. - -Once you have the device configuration set up you can initialize the device. When initializing a device you need to allocate memory for the device object -beforehand. This gives the application complete control over how the memory is allocated. In the example below we initialize a playback device on the stack, -but you could allocate it on the heap if that suits your situation better. - - ```c - void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount) - { - // In playback mode copy data to pOutput. In capture mode read data from pInput. In full-duplex mode, both pOutput and pInput will be valid and you can - // move data from pInput into pOutput. Never process more than frameCount frames. - } - - ... - - ma_device_config config = ma_device_config_init(ma_device_type_playback); - config.playback.format = MY_FORMAT; - config.playback.channels = MY_CHANNEL_COUNT; - config.sampleRate = MY_SAMPLE_RATE; - config.dataCallback = data_callback; - config.pUserData = pMyCustomData; // Can be accessed from the device object (device.pUserData). - - ma_device device; - if (ma_device_init(NULL, &config, &device) != MA_SUCCESS) { - ... An error occurred ... - } - - ma_device_start(&device); // The device is sleeping by default so you'll need to start it manually. - - ... - - ma_device_uninit(&device); // This will stop the device so no need to do that manually. - ``` - -In the example above, `data_callback()` is where audio data is written and read from the device. The idea is in playback mode you cause sound to be emitted -from the speakers by writing audio data to the output buffer (`pOutput` in the example). In capture mode you read data from the input buffer (`pInput`) to -extract sound captured by the microphone. The `frameCount` parameter tells you how many frames can be written to the output buffer and read from the input -buffer. A "frame" is one sample for each channel. For example, in a stereo stream (2 channels), one frame is 2 samples: one for the left, one for the right. -The channel count is defined by the device config. The size in bytes of an individual sample is defined by the sample format which is also specified in the -device config. Multi-channel audio data is always interleaved, which means the samples for each frame are stored next to each other in memory. For example, in -a stereo stream the first pair of samples will be the left and right samples for the first frame, the second pair of samples will be the left and right samples -for the second frame, etc. - -The configuration of the device is defined by the `ma_device_config` structure. The config object is always initialized with `ma_device_config_init()`. It's -important to always initialize the config with this function as it initializes it with logical defaults and ensures your program doesn't break when new members -are added to the `ma_device_config` structure. The example above uses a fairly simple and standard device configuration. The call to `ma_device_config_init()` -takes a single parameter, which is whether or not the device is a playback, capture, duplex or loopback device (loopback devices are not supported on all -backends). The `config.playback.format` member sets the sample format which can be one of the following (all formats are native-endian): - - |---------------|----------------------------------------|---------------------------| - | Symbol | Description | Range | - |---------------|----------------------------------------|---------------------------| - | ma_format_f32 | 32-bit floating point | [-1, 1] | - | ma_format_s16 | 16-bit signed integer | [-32768, 32767] | - | ma_format_s24 | 24-bit signed integer (tightly packed) | [-8388608, 8388607] | - | ma_format_s32 | 32-bit signed integer | [-2147483648, 2147483647] | - | ma_format_u8 | 8-bit unsigned integer | [0, 255] | - |---------------|----------------------------------------|---------------------------| - -The `config.playback.channels` member sets the number of channels to use with the device. The channel count cannot exceed MA_MAX_CHANNELS. The -`config.sampleRate` member sets the sample rate (which must be the same for both playback and capture in full-duplex configurations). This is usually set to -44100 or 48000, but can be set to anything. It's recommended to keep this between 8000 and 384000, however. - -Note that leaving the format, channel count and/or sample rate at their default values will result in the internal device's native configuration being used -which is useful if you want to avoid the overhead of miniaudio's automatic data conversion. - -In addition to the sample format, channel count and sample rate, the data callback and user data pointer are also set via the config. The user data pointer is -not passed into the callback as a parameter, but is instead set to the `pUserData` member of `ma_device` which you can access directly since all miniaudio -structures are transparent. - -Initializing the device is done with `ma_device_init()`. This will return a result code telling you what went wrong, if anything. On success it will return -`MA_SUCCESS`. After initialization is complete the device will be in a stopped state. To start it, use `ma_device_start()`. Uninitializing the device will stop -it, which is what the example above does, but you can also stop the device with `ma_device_stop()`. To resume the device simply call `ma_device_start()` again. -Note that it's important to never stop or start the device from inside the callback. This will result in a deadlock. Instead you set a variable or signal an -event indicating that the device needs to stop and handle it in a different thread. The following APIs must never be called inside the callback: - - ma_device_init() - ma_device_init_ex() - ma_device_uninit() - ma_device_start() - ma_device_stop() - -You must never try uninitializing and reinitializing a device inside the callback. You must also never try to stop and start it from inside the callback. There -are a few other things you shouldn't do in the callback depending on your requirements, however this isn't so much a thread-safety thing, but rather a real- -time processing thing which is beyond the scope of this introduction. - -The example above demonstrates the initialization of a playback device, but it works exactly the same for capture. All you need to do is change the device type -from `ma_device_type_playback` to `ma_device_type_capture` when setting up the config, like so: - - ```c - ma_device_config config = ma_device_config_init(ma_device_type_capture); - config.capture.format = MY_FORMAT; - config.capture.channels = MY_CHANNELS; - ``` - -In the data callback you just read from the input buffer (`pInput` in the example above) and leave the output buffer alone (it will be set to NULL when the -device type is set to `ma_device_type_capture`). - -These are the available device types and how you should handle the buffers in the callback: - - |-------------------------|--------------------------------------------------------| - | Device Type | Callback Behavior | - |-------------------------|--------------------------------------------------------| - | ma_device_type_playback | Write to output buffer, leave input buffer untouched. | - | ma_device_type_capture | Read from input buffer, leave output buffer untouched. | - | ma_device_type_duplex | Read from input buffer, write to output buffer. | - | ma_device_type_loopback | Read from input buffer, leave output buffer untouched. | - |-------------------------|--------------------------------------------------------| - -You will notice in the example above that the sample format and channel count is specified separately for playback and capture. This is to support different -data formats between the playback and capture devices in a full-duplex system. An example may be that you want to capture audio data as a monaural stream (one -channel), but output sound to a stereo speaker system. Note that if you use different formats between playback and capture in a full-duplex configuration you -will need to convert the data yourself. There are functions available to help you do this which will be explained later. - -The example above did not specify a physical device to connect to which means it will use the operating system's default device. If you have multiple physical -devices connected and you want to use a specific one you will need to specify the device ID in the configuration, like so: - - ``` - config.playback.pDeviceID = pMyPlaybackDeviceID; // Only if requesting a playback or duplex device. - config.capture.pDeviceID = pMyCaptureDeviceID; // Only if requesting a capture, duplex or loopback device. - ``` - -To retrieve the device ID you will need to perform device enumeration, however this requires the use of a new concept call the "context". Conceptually speaking -the context sits above the device. There is one context to many devices. The purpose of the context is to represent the backend at a more global level and to -perform operations outside the scope of an individual device. Mainly it is used for performing run-time linking against backend libraries, initializing -backends and enumerating devices. The example below shows how to enumerate devices. - - ```c - ma_context context; - if (ma_context_init(NULL, 0, NULL, &context) != MA_SUCCESS) { - // Error. - } - - ma_device_info* pPlaybackDeviceInfos; - ma_uint32 playbackDeviceCount; - ma_device_info* pCaptureDeviceInfos; - ma_uint32 captureDeviceCount; - if (ma_context_get_devices(&context, &pPlaybackDeviceInfos, &playbackDeviceCount, &pCaptureDeviceInfos, &captureDeviceCount) != MA_SUCCESS) { - // Error. - } - - // Loop over the each device info and do something with it. Here we just print the name with their index. You may want to give the user the - // opportunity to choose which device they'd prefer. - for (ma_uint32 iDevice = 0; iDevice < playbackDeviceCount; iDevice += 1) { - printf("%d - %s\n", iDevice, pPlaybackDeviceInfos[iDevice].name); - } - - ma_device_config config = ma_device_config_init(ma_device_type_playback); - config.playback.pDeviceID = &pPlaybackDeviceInfos[chosenPlaybackDeviceIndex].id; - config.playback.format = MY_FORMAT; - config.playback.channels = MY_CHANNEL_COUNT; - config.sampleRate = MY_SAMPLE_RATE; - config.dataCallback = data_callback; - config.pUserData = pMyCustomData; - - ma_device device; - if (ma_device_init(&context, &config, &device) != MA_SUCCESS) { - // Error - } - - ... - - ma_device_uninit(&device); - ma_context_uninit(&context); - ``` - -The first thing we do in this example is initialize a `ma_context` object with `ma_context_init()`. The first parameter is a pointer to a list of `ma_backend` -values which are used to override the default backend priorities. When this is NULL, as in this example, miniaudio's default priorities are used. The second -parameter is the number of backends listed in the array pointed to by the first paramter. The third parameter is a pointer to a `ma_context_config` object -which can be NULL, in which case defaults are used. The context configuration is used for setting the logging callback, custom memory allocation callbacks, -user-defined data and some backend-specific configurations. - -Once the context has been initialized you can enumerate devices. In the example above we use the simpler `ma_context_get_devices()`, however you can also use a -callback for handling devices by using `ma_context_enumerate_devices()`. When using `ma_context_get_devices()` you provide a pointer to a pointer that will, -upon output, be set to a pointer to a buffer containing a list of `ma_device_info` structures. You also provide a pointer to an unsigned integer that will -receive the number of items in the returned buffer. Do not free the returned buffers as their memory is managed internally by miniaudio. - -The `ma_device_info` structure contains an `id` member which is the ID you pass to the device config. It also contains the name of the device which is useful -for presenting a list of devices to the user via the UI. - -When creating your own context you will want to pass it to `ma_device_init()` when initializing the device. Passing in NULL, like we do in the first example, -will result in miniaudio creating the context for you, which you don't want to do since you've already created a context. Note that internally the context is -only tracked by it's pointer which means you must not change the location of the `ma_context` object. If this is an issue, consider using `malloc()` to -allocate memory for the context. - - - -Building -======== -miniaudio should work cleanly out of the box without the need to download or install any dependencies. See below for platform-specific details. - - -Windows -------- -The Windows build should compile clean on all popular compilers without the need to configure any include paths nor link to any libraries. - -macOS and iOS -------------- -The macOS build should compile clean without the need to download any dependencies or link to any libraries or frameworks. The iOS build needs to be compiled -as Objective-C (sorry) and will need to link the relevant frameworks but should Just Work with Xcode. Compiling through the command line requires linking to --lpthread and -lm. - -Linux ------ -The Linux build only requires linking to -ldl, -lpthread and -lm. You do not need any development packages. - -BSD ---- -The BSD build only requires linking to -lpthread and -lm. NetBSD uses audio(4), OpenBSD uses sndio and FreeBSD uses OSS. - -Android -------- -AAudio is the highest priority backend on Android. This should work out out of the box without needing any kind of compiler configuration. Support for AAudio -starts with Android 8 which means older versions will fall back to OpenSL|ES which requires API level 16+. - -Emscripten ----------- -The Emscripten build emits Web Audio JavaScript directly and should Just Work without any configuration. You cannot use -std=c* compiler flags, nor -ansi. - - -Build Options -------------- -#define these options before including miniaudio.h. - -#define MA_NO_WASAPI - Disables the WASAPI backend. - -#define MA_NO_DSOUND - Disables the DirectSound backend. - -#define MA_NO_WINMM - Disables the WinMM backend. - -#define MA_NO_ALSA - Disables the ALSA backend. - -#define MA_NO_PULSEAUDIO - Disables the PulseAudio backend. - -#define MA_NO_JACK - Disables the JACK backend. - -#define MA_NO_COREAUDIO - Disables the Core Audio backend. - -#define MA_NO_SNDIO - Disables the sndio backend. - -#define MA_NO_AUDIO4 - Disables the audio(4) backend. - -#define MA_NO_OSS - Disables the OSS backend. - -#define MA_NO_AAUDIO - Disables the AAudio backend. - -#define MA_NO_OPENSL - Disables the OpenSL|ES backend. - -#define MA_NO_WEBAUDIO - Disables the Web Audio backend. - -#define MA_NO_NULL - Disables the null backend. - -#define MA_NO_DECODING - Disables the decoding APIs. - -#define MA_NO_DEVICE_IO - Disables playback and recording.

The value to pass to internal calls to CoInitializeEx(). Defaults to COINIT_MULTITHREADED. - - - -Definitions -=========== -This section defines common terms used throughout miniaudio. Unfortunately there is often ambiguity in the use of terms throughout the audio space, so this -section is intended to clarify how miniaudio uses each term. - -Sample ------- -A sample is a single unit of audio data. If the sample format is f32, then one sample is one 32-bit floating point number. - -Frame / PCM Frame ------------------ -A frame is a groups of samples equal to the number of channels. For a stereo stream a frame is 2 samples, a mono frame is 1 sample, a 5.1 surround sound frame -is 6 samples, etc. The terms "frame" and "PCM frame" are the same thing in miniaudio. Note that this is different to a compressed frame. If ever miniaudio -needs to refer to a compressed frame, such as a FLAC frame, it will always clarify what it's referring to with something like "FLAC frame" or whatnot. - -Channel -------- -A stream of monaural audio that is emitted from an individual speaker in a speaker system, or received from an individual microphone in a microphone system. A -stereo stream has two channels (a left channel, and a right channel), a 5.1 surround sound system has 6 channels, etc. Some audio systems refer to a channel as -a complex audio stream that's mixed with other channels to produce the final mix - this is completely different to miniaudio's use of the term "channel" and -should not be confused. - -Sample Rate ------------ -The sample rate in miniaudio is always expressed in Hz, such as 44100, 48000, etc. It's the number of PCM frames that are processed per second. - -Formats -------- -Throughout miniaudio you will see references to different sample formats: - - |---------------|----------------------------------------|---------------------------| - | Symbol | Description | Range | - |---------------|----------------------------------------|---------------------------| - | ma_format_f32 | 32-bit floating point | [-1, 1] | - | ma_format_s16 | 16-bit signed integer | [-32768, 32767] | - | ma_format_s24 | 24-bit signed integer (tightly packed) | [-8388608, 8388607] | - | ma_format_s32 | 32-bit signed integer | [-2147483648, 2147483647] | - | ma_format_u8 | 8-bit unsigned integer | [0, 255] | - |---------------|----------------------------------------|---------------------------| - -All formats are native-endian. - - - -Decoding -======== -The `ma_decoder` API is used for reading audio files. To enable a decoder you must #include the header of the relevant backend library before the -implementation of miniaudio. You can find copies of these in the "extras" folder in the miniaudio repository (https://github.com/dr-soft/miniaudio). - -The table below are the supported decoding backends: - - |--------|-----------------| - | Type | Backend Library | - |--------|-----------------| - | WAV | dr_wav.h | - | FLAC | dr_flac.h | - | MP3 | dr_mp3.h | - | Vorbis | stb_vorbis.c | - |--------|-----------------| - -The code below is an example of how to enable decoding backends: - - ```c - #include "dr_flac.h" // Enables FLAC decoding. - #include "dr_mp3.h" // Enables MP3 decoding. - #include "dr_wav.h" // Enables WAV decoding. - - #define MINIAUDIO_IMPLEMENTATION - #include "miniaudio.h" - ``` - -A decoder can be initialized from a file with `ma_decoder_init_file()`, a block of memory with `ma_decoder_init_memory()`, or from data delivered via callbacks -with `ma_decoder_init()`. Here is an example for loading a decoder from a file: - - ```c - ma_decoder decoder; - ma_result result = ma_decoder_init_file("MySong.mp3", NULL, &decoder); - if (result != MA_SUCCESS) { - return false; // An error occurred. - } - - ... - - ma_decoder_uninit(&decoder); - ``` - -When initializing a decoder, you can optionally pass in a pointer to a ma_decoder_config object (the NULL argument in the example above) which allows you to -configure the output format, channel count, sample rate and channel map: - - ```c - ma_decoder_config config = ma_decoder_config_init(ma_format_f32, 2, 48000); - ``` - -When passing in NULL for decoder config in `ma_decoder_init*()`, the output format will be the same as that defined by the decoding backend. - -Data is read from the decoder as PCM frames: - - ```c - ma_uint64 framesRead = ma_decoder_read_pcm_frames(pDecoder, pFrames, framesToRead); - ``` - -You can also seek to a specific frame like so: - - ```c - ma_result result = ma_decoder_seek_to_pcm_frame(pDecoder, targetFrame); - if (result != MA_SUCCESS) { - return false; // An error occurred. - } - ``` - -When loading a decoder, miniaudio uses a trial and error technique to find the appropriate decoding backend. This can be unnecessarily inefficient if the type -is already known. In this case you can use the `_wav`, `_mp3`, etc. varients of the aforementioned initialization APIs: - - ```c - ma_decoder_init_wav() - ma_decoder_init_mp3() - ma_decoder_init_memory_wav() - ma_decoder_init_memory_mp3() - ma_decoder_init_file_wav() - ma_decoder_init_file_mp3() - etc. - ``` - -The `ma_decoder_init_file()` API will try using the file extension to determine which decoding backend to prefer. - - - -Sample Format Conversion -======================== -Conversion between sample formats is achieved with the `ma_pcm_*_to_*()`, `ma_pcm_convert()` and `ma_convert_pcm_frames_format()` APIs. Use `ma_pcm_*_to_*()` -to convert between two specific formats. Use `ma_pcm_convert()` to convert based on a `ma_format` variable. Use `ma_convert_pcm_frames_format()` to convert -PCM frames where you want to specify the frame count and channel count as a variable instead of the total sample count. - -Dithering ---------- -Dithering can be set using ditherMode parmater. - -The different dithering modes include the following, in order of efficiency: - - |-----------|--------------------------| - | Type | Enum Token | - |-----------|--------------------------| - | None | ma_dither_mode_none | - | Rectangle | ma_dither_mode_rectangle | - | Triangle | ma_dither_mode_triangle | - |-----------|--------------------------| - -Note that even if the dither mode is set to something other than `ma_dither_mode_none`, it will be ignored for conversions where dithering is not needed. -Dithering is available for the following conversions: - - s16 -> u8 - s24 -> u8 - s32 -> u8 - f32 -> u8 - s24 -> s16 - s32 -> s16 - f32 -> s16 - -Note that it is not an error to pass something other than ma_dither_mode_none for conversions where dither is not used. It will just be ignored. - - - -Channel Conversion -================== -Channel conversion is used for channel rearrangement and conversion from one channel count to another. The `ma_channel_converter` API is used for channel -conversion. Below is an example of initializing a simple channel converter which converts from mono to stereo. - - ```c - ma_channel_converter_config config = ma_channel_converter_config_init(ma_format, 1, NULL, 2, NULL, ma_channel_mix_mode_default, NULL); - result = ma_channel_converter_init(&config, &converter); - if (result != MA_SUCCESS) { - // Error. - } - ``` - -To process perform the conversion simply call `ma_channel_converter_process_pcm_frames()` like so: - - ```c - ma_result result = ma_channel_converter_process_pcm_frames(&converter, pFramesOut, pFramesIn, frameCount); - if (result != MA_SUCCESS) { - // Error. - } - ``` - -It is up to the caller to ensure the output buffer is large enough to accomodate the new PCM frames. - -The only formats supported are `ma_format_s16` and `ma_format_f32`. If you need another format you need to convert your data manually which you can do with -`ma_pcm_convert()`, etc. - -Input and output PCM frames are always interleaved. Deinterleaved layouts are not supported. - - -Channel Mapping ---------------- -In addition to converting from one channel count to another, like the example above, The channel converter can also be used to rearrange channels. When -initializing the channel converter, you can optionally pass in channel maps for both the input and output frames. If the channel counts are the same, and each -channel map contains the same channel positions with the exception that they're in a different order, a simple shuffling of the channels with be performed. If, -however, there is not a 1:1 mapping of channel positions, or the channel counts differ, the input channels will be mixed based on a mixing -mode which is specified when initializing the `ma_channel_converter_config` object. - -When converting from mono to multi-channel, the mono channel is simply copied to each output channel. When going the other way around, the audio of each output -channel is simply averaged and copied to the mono channel. - -In more complicated cases blending is used. The `ma_channel_mix_mode_simple` mode will drop excess channels and silence extra channels. For example, converting -from 4 to 2 channels, the 3rd and 4th channels will be dropped, whereas converting from 2 to 4 channels will put silence into the 3rd and 4th channels. - -The `ma_channel_mix_mode_rectangle` mode uses spacial locality based on a rectangle to compute a simple distribution between input and output. Imagine sitting -in the middle of a room, with speakers on the walls representing channel positions. The MA_CHANNEL_FRONT_LEFT position can be thought of as being in the corner -of the front and left walls. - -Finally, the `ma_channel_mix_mode_custom_weights` mode can be used to use custom user-defined weights. Custom weights can be passed in as the last parameter of -`ma_channel_converter_config_init()`. - -Predefined channel maps can be retrieved with `ma_get_standard_channel_map()`. This takes a `ma_standard_channel_map` enum as it's first parameter, which can -be one of the following: - - |-----------------------------------|-----------------------------------------------------------| - | Name | Description | - |-----------------------------------|-----------------------------------------------------------| - | ma_standard_channel_map_default | Default channel map used by miniaudio.

This | - | | is equivalent to the same | - | | mapping as the device. | - |---------------|------------------------------| - - - -Resampling -========== -Resampling is achieved with the `ma_resampler` object. To create a resampler object, do something like the following: - - ```c - ma_resampler_config config = ma_resampler_config_init(ma_format_s16, channels, sampleRateIn, sampleRateOut, ma_resample_algorithm_linear); - ma_resampler resampler; - ma_result result = ma_resampler_init(&config, &resampler); - if (result != MA_SUCCESS) { - // An error occurred... - } - ``` - -Do the following to uninitialize the resampler: - - ```c - ma_resampler_uninit(&resampler); - ``` - -The following example shows how data can be processed - - ```c - ma_uint64 frameCountIn = 1000; - ma_uint64 frameCountOut = 2000; - ma_result result = ma_resampler_process_pcm_frames(&resampler, pFramesIn, &frameCountIn, pFramesOut, &frameCountOut); - if (result != MA_SUCCESS) { - // An error occurred... - } - - // At this point, frameCountIn contains the number of input frames that were consumed and frameCountOut contains the number of output frames written. - ``` - -To initialize the resampler you first need to set up a config (`ma_resampler_config`) with `ma_resampler_config_init()`. You need to specify the sample format -you want to use, the number of channels, the input and output sample rate, and the algorithm. - -The sample format can be either `ma_format_s16` or `ma_format_f32`. If you need a different format you will need to perform pre- and post-conversions yourself -where necessary. Note that the format is the same for both input and output. The format cannot be changed after initialization. - -The resampler supports multiple channels and is always interleaved (both input and output). The channel count cannot be changed after initialization. - -The sample rates can be anything other than zero, and are always specified in hertz. They should be set to something like 44100, etc. The sample rate is the -only configuration property that can be changed after initialization. - -The miniaudio resampler supports multiple algorithms: - - |-----------|------------------------------| - | Algorithm | Enum Token | - |-----------|------------------------------| - | Linear | ma_resample_algorithm_linear | - | Speex | ma_resample_algorithm_speex | - |-----------|------------------------------| - -Because Speex is not public domain it is strictly opt-in and the code is stored in separate files. if you opt-in to the Speex backend you will need to consider -it's license, the text of which can be found in it's source files in "extras/speex_resampler". Details on how to opt-in to the Speex resampler is explained in -the Speex Resampler section below. - -The algorithm cannot be changed after initialization. - -Processing always happens on a per PCM frame basis and always assumes interleaved input and output. De-interleaved processing is not supported. To process -frames, use `ma_resampler_process_pcm_frames()`. On input, this function takes the number of output frames you can fit in the output buffer and the number of -input frames contained in the input buffer. On output these variables contain the number of output frames that were written to the output buffer and the -number of input frames that were consumed in the process. You can pass in NULL for the input buffer in which case it will be treated as an infinitely large -buffer of zeros. The output buffer can also be NULL, in which case the processing will be treated as seek. - -The sample rate can be changed dynamically on the fly. You can change this with explicit sample rates with `ma_resampler_set_rate()` and also with a decimal -ratio with `ma_resampler_set_rate_ratio()`. The ratio is in/out. - -Sometimes it's useful to know exactly how many input frames will be required to output a specific number of frames. You can calculate this with -`ma_resampler_get_required_input_frame_count()`. Likewise, it's sometimes useful to know exactly how many frames would be output given a certain number of -input frames. You can do this with `ma_resampler_get_expected_output_frame_count()`. - -Due to the nature of how resampling works, the resampler introduces some latency. This can be retrieved in terms of both the input rate and the output rate -with `ma_resampler_get_input_latency()` and `ma_resampler_get_output_latency()`. - - -Resampling Algorithms ---------------------- -The choice of resampling algorithm depends on your situation and requirements. The linear resampler is the most efficient and has the least amount of latency, -but at the expense of poorer quality. The Speex resampler is higher quality, but slower with more latency. It also performs several heap applications -internally for memory management. - - -Linear Resampling ------------------ -The linear resampler is the fastest, but comes at the expense of poorer quality. There is, however, some control over the quality of the linear resampler which -may make it a suitable option depending on your requirements. - -The linear resampler performs low-pass filtering before or after downsampling or upsampling, depending on the sample rates you're converting between. When -decreasing the sample rate, the low-pass filter will be applied before downsampling. When increasing the rate it will be performed after upsampling. By default -a second order low-pass filter will be applied. To improve quality you can chain low-pass filters together, up to a maximum of `MA_MAX_RESAMPLER_LPF_FILTERS`. -This comes at the expense of increased computational cost and latency. You can also disable filtering altogether by setting the filter count to 0. The filter -count is controlled with the `lpfCount` config variable. - -The low-pass filter has a cutoff frequency which defaults to half the sample rate of the lowest of the input and output sample rates (Nyquist Frequency). This -can be controlled with the `lpfNyquistFactor` config variable. This defaults to 1, and should be in the range of 0..1, although a value of 0 does not make -sense and should be avoided. A value of 1 will use the Nyquist Frequency as the cutoff. A value of 0.5 will use half the Nyquist Frequency as the cutoff, etc. -Values less than 1 will result in more washed out sound due to more of the higher frequencies being removed. This config variable has no impact on performance -and is a purely perceptual configuration. - -The API for the linear resampler is the same as the main resampler API, only it's called `ma_linear_resampler`. - - -Speex Resampling ----------------- -The Speex resampler is made up of third party code which is released under the BSD license. Because it is licensed differently to miniaudio, which is public -domain, it is strictly opt-in and all of it's code is stored in separate files. If you opt-in to the Speex resampler you must consider the license text in it's -source files. To opt-in, you must first #include the following file before the implementation of miniaudio.h: - - #include "extras/speex_resampler/ma_speex_resampler.h" - -Both the header and implementation is contained within the same file. To implementation can be included in your program like so: - - #define MINIAUDIO_SPEEX_RESAMPLER_IMPLEMENTATION - #include "extras/speex_resampler/ma_speex_resampler.h" - -Note that even if you opt-in to the Speex backend, miniaudio won't use it unless you explicitly ask for it in the respective config of the object you are -initializing. If you try to use the Speex resampler without opting in, initialization of the `ma_resampler` object will fail with `MA_NO_BACKEND`. - -The only configuration option to consider with the Speex resampler is the `speex.quality` config variable. This is a value between 0 and 10, with 0 being -the worst/fastest and 10 being the best/slowest. The default value is 3. - - - - -General Data Conversion -======================= -The `ma_data_converter` API can be used to wrap sample format conversion, channel conversion and resampling into one operation. This is what miniaudio uses -internally to convert between the format requested when the device was initialized and the format of the backend's native device. The API for general data -conversion is very similar to the resampling API. Create a `ma_data_converter` object like this: - - ```c - ma_data_converter_config config = ma_data_converter_config_init(inputFormat, outputFormat, inputChannels, outputChannels, inputSampleRate, outputSampleRate); - ma_data_converter converter; - ma_result result = ma_data_converter_init(&config, &converter); - if (result != MA_SUCCESS) { - // An error occurred... - } - ``` - -In the example above we use `ma_data_converter_config_init()` to initialize the config, however there's many more properties that can be configured, such as -channel maps and resampling quality. Something like the following may be more suitable depending on your requirements: - - ```c - ma_data_converter_config config = ma_data_converter_config_init_default(); - config.formatIn = inputFormat; - config.formatOut = outputFormat; - config.channelsIn = inputChannels; - config.channelsOut = outputChannels; - config.sampleRateIn = inputSampleRate; - config.sampleRateOut = outputSampleRate; - ma_get_standard_channel_map(ma_standard_channel_map_flac, config.channelCountIn, config.channelMapIn); - config.resampling.linear.lpfCount = MA_MAX_RESAMPLER_LPF_FILTERS; - ``` - -Do the following to uninitialize the data converter: - - ```c - ma_data_converter_uninit(&converter); - ``` - -The following example shows how data can be processed - - ```c - ma_uint64 frameCountIn = 1000; - ma_uint64 frameCountOut = 2000; - ma_result result = ma_data_converter_process_pcm_frames(&converter, pFramesIn, &frameCountIn, pFramesOut, &frameCountOut); - if (result != MA_SUCCESS) { - // An error occurred... - } - - // At this point, frameCountIn contains the number of input frames that were consumed and frameCountOut contains the number of output frames written. - ``` - -The data converter supports multiple channels and is always interleaved (both input and output). The channel count cannot be changed after initialization. - -The sample rates can be anything other than zero, and are always specified in hertz. They should be set to something like 44100, etc. The sample rate is the -only configuration property that can be changed after initialization, but only if the `resampling.allowDynamicSampleRate` member of `ma_data_converter_config` -is set to MA_TRUE. To change the sample rate, use `ma_data_converter_set_rate()` or `ma_data_converter_set_rate_ratio()`. The ratio must be in/out. The -resampling algorithm cannot be changed after initialization. - -Processing always happens on a per PCM frame basis and always assumes interleaved input and output. De-interleaved processing is not supported. To process -frames, use `ma_data_converter_process_pcm_frames()`. On input, this function takes the number of output frames you can fit in the output buffer and the number -of input frames contained in the input buffer. On output these variables contain the number of output frames that were written to the output buffer and the -number of input frames that were consumed in the process. You can pass in NULL for the input buffer in which case it will be treated as an infinitely large -buffer of zeros. The output buffer can also be NULL, in which case the processing will be treated as seek. - -Sometimes it's useful to know exactly how many input frames will be required to output a specific number of frames. You can calculate this with -`ma_data_converter_get_required_input_frame_count()`. Likewise, it's sometimes useful to know exactly how many frames would be output given a certain number of -input frames. You can do this with `ma_data_converter_get_expected_output_frame_count()`. - -Due to the nature of how resampling works, the data converter introduces some latency if resampling is required. This can be retrieved in terms of both the -input rate and the output rate with `ma_data_converter_get_input_latency()` and `ma_data_converter_get_output_latency()`. - - - - -Biquad Filtering -================ -Biquad filtering is achieved with the `ma_biquad` API. Example: - - ```c - ma_biquad_config config = ma_biquad_config_init(ma_format_f32, channels, b0, b1, b2, a0, a1, a2); - ma_result result = ma_biquad_init(&config, &biquad); - if (result != MA_SUCCESS) { - // Error. - } - - ... - - ma_biquad_process_pcm_frames(&biquad, pFramesOut, pFramesIn, frameCount); - ``` - -Biquad filtering is implemented using transposed direct form 2. The numerator coefficients are b0, b1 and b2, and the denominator coefficients are a0, a1 and -a2. The a0 coefficient is required and coefficients must not be pre-normalized. - -Supported formats are `ma_format_s16` and `ma_format_f32`. If you need to use a different format you need to convert it yourself beforehand. When using -`ma_format_s16` the biquad filter will use fixed point arithmetic. When using `ma_format_f32`, floating point arithmetic will be used. - -Input and output frames are always interleaved. - -Filtering can be applied in-place by passing in the same pointer for both the input and output buffers, like so: - - ```c - ma_biquad_process_pcm_frames(&biquad, pMyData, pMyData, frameCount); - ``` - -If you need to change the values of the coefficients, but maintain the values in the registers you can do so with `ma_biquad_reinit()`. This is useful if you -need to change the properties of the filter while keeping the values of registers valid to avoid glitching or whatnot. Do not use `ma_biquad_init()` for this -as it will do a full initialization which involves clearing the registers to 0. Note that changing the format or channel count after initialization is invalid -and will result in an error. - - - -Low-Pass, High-Pass and Band-Pass Filtering -=========================================== -Low-pass, high-pass and band-pass filtering is achieved with the `ma_lpf`, `ma_hpf` and `ma_bpf` APIs respective. Low-pass filter example: - - ```c - ma_lpf_config config = ma_lpf_config_init(ma_format_f32, channels, sampleRate, cutoffFrequency); - ma_result result = ma_lpf_init(&config, &lpf); - if (result != MA_SUCCESS) { - // Error. - } - - ... - - ma_lpf_process_pcm_frames(&lpf, pFramesOut, pFramesIn, frameCount); - ``` - -Supported formats are `ma_format_s16` and` ma_format_f32`. If you need to use a different format you need to convert it yourself beforehand. Input and output -frames are always interleaved. - -Filtering can be applied in-place by passing in the same pointer for both the input and output buffers, like so: - - ```c - ma_lpf_process_pcm_frames(&lpf, pMyData, pMyData, frameCount); - ``` - -These filters are implemented as a biquad filter. If you need to increase the filter order, simply chain multiple filters together. - - ```c - for (iFilter = 0; iFilter < filterCount; iFilter += 1) { - ma_lpf_process_pcm_frames(&lpf[iFilter], pMyData, pMyData, frameCount); - } - ``` - -If you need to change the configuration of the filter, but need to maintain the state of internal registers you can do so with `ma_lpf_reinit()`. This may be -useful if you need to change the sample rate and/or cutoff frequency dynamically while maintaing smooth transitions. Note that changing the format or channel -count after initialization is invalid and will result in an error. - -The example code above is for low-pass filters, but the same applies for high-pass and band-pass filters, only you should use the `ma_hpf` and `ma_bpf` APIs -instead. - - - -Waveforms -========= -miniaudio supports generation of sine, square, triangle and sawtooth waveforms. This is achieved with the `ma_waveform` API. Example: - - ```c - ma_waveform waveform; - ma_result result = ma_waveform_init(ma_waveform_type_sine, amplitude, frequency, sampleRate, &waveform); - if (result != MA_SUCCESS) { - // Error. - } - - ... - - ma_waveform_read_pcm_frames(&waveform, pOutput, frameCount, FORMAT, CHANNELS); - ``` - -The amplitude, frequency and sample rate can be changed dynamically with `ma_waveform_set_amplitude()`, `ma_waveform_set_frequency()` and -`ma_waveform_set_sample_rate()` respectively. - - - -Ring Buffers -============ -miniaudio supports lock free (single producer, single consumer) ring buffers which are exposed via the `ma_rb` and `ma_pcm_rb` APIs. The `ma_rb` API operates -on bytes, whereas the `ma_pcm_rb` operates on PCM frames. They are otherwise identical as `ma_pcm_rb` is just a wrapper around `ma_rb`. - -Unlike most other APIs in miniaudio, ring buffers support both interleaved and deinterleaved streams. The caller can also allocate their own backing memory for -the ring buffer to use internally for added flexibility. Otherwise the ring buffer will manage it's internal memory for you. - -The examples below use the PCM frame variant of the ring buffer since that's most likely the one you will want to use. To initialize a ring buffer, do -something like the following: - - ```c - ma_pcm_rb rb; - ma_result result = ma_pcm_rb_init(FORMAT, CHANNELS, BUFFER_SIZE_IN_FRAMES, NULL, NULL, &rb); - if (result != MA_SUCCESS) { - // Error - } - ``` - -The `ma_pcm_rb_init()` function takes the sample format and channel count as parameters because it's the PCM varient of the ring buffer API. For the regular -ring buffer that operates on bytes you would call `ma_rb_init()` which leaves these out and just takes the size of the buffer in bytes instead of frames. The -fourth parameter is an optional pre-allocated buffer and the fifth parameter is a pointer to a `ma_allocation_callbacks` structure for custom memory allocation -routines. Passing in NULL for this results in MA_MALLOC() and MA_FREE() being used. - -Use `ma_pcm_rb_init_ex()` if you need a deinterleaved buffer. The data for each sub-buffer is offset from each other based on the stride. To manage your sub- -buffers you can use `ma_pcm_rb_get_subbuffer_stride()`, `ma_pcm_rb_get_subbuffer_offset()` and `ma_pcm_rb_get_subbuffer_ptr()`. - -Use 'ma_pcm_rb_acquire_read()` and `ma_pcm_rb_acquire_write()` to retrieve a pointer to a section of the ring buffer. You specify the number of frames you -need, and on output it will set to what was actually acquired. If the read or write pointer is positioned such that the number of frames requested will require -a loop, it will be clamped to the end of the buffer. Therefore, the number of frames you're given may be less than the number you requested. - -After calling `ma_pcm_rb_acquire_read()` or `ma_pcm_rb_acquire_write()`, you do your work on the buffer and then "commit" it with `ma_pcm_rb_commit_read()` or -`ma_pcm_rb_commit_write()`. This is where the read/write pointers are updated. When you commit you need to pass in the buffer that was returned by the earlier -call to `ma_pcm_rb_acquire_read()` or `ma_pcm_rb_acquire_write()` and is only used for validation. The number of frames passed to `ma_pcm_rb_commit_read()` and -`ma_pcm_rb_commit_write()` is what's used to increment the pointers. - -If you want to correct for drift between the write pointer and the read pointer you can use a combination of `ma_pcm_rb_pointer_distance()`, -`ma_pcm_rb_seek_read()` and `ma_pcm_rb_seek_write()`. Note that you can only move the pointers forward, and you should only move the read pointer forward via -the consumer thread, and the write pointer forward by the producer thread. If there is too much space between the pointers, move the read pointer forward. If -there is too little space between the pointers, move the write pointer forward. - -You can use a ring buffer at the byte level instead of the PCM frame level by using the `ma_rb` API. This is exactly the sample, only you will use the `ma_rb` -functions instead of `ma_pcm_rb` and instead of frame counts you'll pass around byte counts. - -The maximum size of the buffer in bytes is 0x7FFFFFFF-(MA_SIMD_ALIGNMENT-1) due to the most significant bit being used to encode a flag and the internally -managed buffers always being aligned to MA_SIMD_ALIGNMENT. - -Note that the ring buffer is only thread safe when used by a single consumer thread and single producer thread. - - - -Backends -======== -The following backends are supported by miniaudio. - - |-------------|-----------------------|--------------------------------------------------------| - | Name | Enum Name | Supported Operating Systems | - |-------------|-----------------------|--------------------------------------------------------| - | WASAPI | ma_backend_wasapi | Windows Vista+ | - | DirectSound | ma_backend_dsound | Windows XP+ | - | WinMM | ma_backend_winmm | Windows XP+ (may work on older versions, but untested) | - | Core Audio | ma_backend_coreaudio | macOS, iOS | - | ALSA | ma_backend_alsa | Linux | - | PulseAudio | ma_backend_pulseaudio | Cross Platform (disabled on Windows, BSD and Android) | - | JACK | ma_backend_jack | Cross Platform (disabled on BSD and Android) | - | sndio | ma_backend_sndio | OpenBSD | - | audio(4) | ma_backend_audio4 | NetBSD, OpenBSD | - | OSS | ma_backend_oss | FreeBSD | - | AAudio | ma_backend_aaudio | Android 8+ | - | OpenSL|ES | ma_backend_opensl | Android (API level 16+) | - | Web Audio | ma_backend_webaudio | Web (via Emscripten) | - | Null | ma_backend_null | Cross Platform (not used on Web) | - |-------------|-----------------------|--------------------------------------------------------| - -Some backends have some nuance details you may want to be aware of. - -WASAPI ------- -- Low-latency shared mode will be disabled when using an application-defined sample rate which is different to the device's native sample rate. To work around - this, set wasapi.noAutoConvertSRC to true in the device config. This is due to IAudioClient3_InitializeSharedAudioStream() failing when the - AUDCLNT_STREAMFLAGS_AUTOCONVERTPCM flag is specified. Setting wasapi.noAutoConvertSRC will result in miniaudio's lower quality internal resampler being used - instead which will in turn enable the use of low-latency shared mode. - -PulseAudio ----------- -- If you experience bad glitching/noise on Arch Linux, consider this fix from the Arch wiki: - https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Glitches,_skips_or_crackling - Alternatively, consider using a different backend such as ALSA. - -Android -------- -- To capture audio on Android, remember to add the RECORD_AUDIO permission to your manifest: - -- With OpenSL|ES, only a single ma_context can be active at any given time. This is due to a limitation with OpenSL|ES. -- With AAudio, only default devices are enumerated. This is due to AAudio not having an enumeration API (devices are enumerated through Java). You can however - perform your own device enumeration through Java and then set the ID in the ma_device_id structure (ma_device_id.aaudio) and pass it to ma_device_init(). -- The backend API will perform resampling where possible. The reason for this as opposed to using miniaudio's built-in resampler is to take advantage of any - potential device-specific optimizations the driver may implement. - -UWP ---- -- UWP only supports default playback and capture devices. -- UWP requires the Microphone capability to be enabled in the application's manifest (Package.appxmanifest): - - ... - - - - - -Web Audio / Emscripten ----------------------- -- You cannot use -std=c* compiler flags, nor -ansi. This only applies to the Emscripten build. -- The first time a context is initialized it will create a global object called "miniaudio" whose primary purpose is to act as a factory for device objects. -- Currently the Web Audio backend uses ScriptProcessorNode's, but this may need to change later as they've been deprecated. -- Google has implemented a policy in their browsers that prevent automatic media output without first receiving some kind of user input. The following web page - has additional details: https://developers.google.com/web/updates/2017/09/autoplay-policy-changes. Starting the device may fail if you try to start playback - without first handling some kind of user input. - - - -Miscellaneous Notes -=================== -- Automatic stream routing is enabled on a per-backend basis. Support is explicitly enabled for WASAPI and Core Audio, however other backends such as - PulseAudio may naturally support it, though not all have been tested. -- The contents of the output buffer passed into the data callback will always be pre-initialized to zero unless the noPreZeroedOutputBuffer config variable in - ma_device_config is set to true, in which case it'll be undefined which will require you to write something to the entire buffer. -- By default miniaudio will automatically clip samples. This only applies when the playback sample format is configured as ma_format_f32.

The idea is you send or receive audio data from the device to either play it back through a speaker, or capture it -from a microphone. Whether or not you should send or receive data from the device (or both) depends on the type of device you are initializing which can be -playback, capture, full-duplex or loopback. (Note that loopback mode is only supported on select backends.) Sending and receiving audio data to and from the -device is done via a callback which is fired by miniaudio at periodic time intervals. - -The frequency at which data is deilvered to and from a device depends on the size of it's period which is defined by a buffer size and a period count. The size -of the buffer can be defined in terms of PCM frames or milliseconds, whichever is more convenient. The size of a period is the size of this buffer, divided by -the period count. Generally speaking, the smaller the period, the lower the latency at the expense of higher CPU usage and increased risk of glitching due to -the more frequent and granular data deliver intervals. The size of a period will depend on your requirements, but miniaudio's defaults should work fine for -most scenarios. If you're building a game you should leave this fairly small, whereas if you're building a simple media player you can make it larger. Note -that the period size you request is actually just a hint - miniaudio will tell the backend what you want, but the backend is ultimately responsible for what it -gives you. You cannot assume you will get exactly what you ask for. - -When delivering data to and from a device you need to make sure it's in the correct format which you can set through the device configuration. You just set the -format that you want to use and miniaudio will perform all of the necessary conversion for you internally. When delivering data to and from the callback you -can assume the format is the same as what you requested when you initialized the device. See Remarks for more details on miniaudio's data conversion pipeline. - - -Parameters ----------- -pContext (in, optional) - A pointer to the context that owns the device. This can be null, in which case it creates a default context internally. - -pConfig (in) - A pointer to the device configuration. Cannot be null. See remarks for details. - -pDevice (out) - A pointer to the device object being initialized. - - -Return Value ------------- -MA_SUCCESS if successful; any other error code otherwise. - - -Thread Safety -------------- -Unsafe. It is not safe to call this function simultaneously for different devices because some backends depend on and mutate global state. The same applies to -calling this at the same time as `ma_device_uninit()`. - - -Callback Safety ---------------- -Unsafe. It is not safe to call this inside any callback. - - -Remarks -------- -Setting `pContext` to NULL will result in miniaudio creating a default context internally and is equivalent to passing in a context initialized like so: - - ```c - ma_context_init(NULL, 0, NULL, &context); - ``` - -Do not set `pContext` to NULL if you are needing to open multiple devices. You can, however, use NULL when initializing the first device, and then use -device.pContext for the initialization of other devices. - -The device can be configured via the `pConfig` argument. The config object is initialized with `ma_device_config_init()`. Individual configuration settings can -then be set directly on the structure. Below are the members of the `ma_device_config` object. - - deviceType - Must be `ma_device_type_playback`, `ma_device_type_capture`, `ma_device_type_duplex` of `ma_device_type_loopback`. - - sampleRate - The sample rate, in hertz. The most common sample rates are 48000 and 44100. Setting this to 0 will use the device's native sample rate. - - periodSizeInFrames - The desired size of a period in PCM frames. If this is 0, `periodSizeInMilliseconds` will be used instead. If both are 0 the default buffer size will - be used depending on the selected performance profile. This value affects latency. See below for details. - - periodSizeInMilliseconds - The desired size of a period in milliseconds. If this is 0, `periodSizeInFrames` will be used instead. If both are 0 the default buffer size will be - used depending on the selected performance profile. The value affects latency. See below for details. - - periods - The number of periods making up the device's entire buffer. The total buffer size is `periodSizeInFrames` or `periodSizeInMilliseconds` multiplied by - this value. This is just a hint as backends will be the ones who ultimately decide how your periods will be configured. - - performanceProfile - A hint to miniaudio as to the performance requirements of your program. Can be either `ma_performance_profile_low_latency` (default) or - `ma_performance_profile_conservative`. This mainly affects the size of default buffers and can usually be left at it's default value. - - noPreZeroedOutputBuffer - When set to true, the contents of the output buffer passed into the data callback will be left undefined. When set to false (default), the contents of - the output buffer will be cleared the zero. You can use this to avoid the overhead of zeroing out the buffer if you know can guarantee that your data - callback will write to every sample in the output buffer, or if you are doing your own clearing. - - noClip - When set to true, the contents of the output buffer passed into the data callback will be clipped after returning. When set to false (default), the - contents of the output buffer are left alone after returning and it will be left up to the backend itself to decide whether or not the clip. This only - applies when the playback sample format is f32. - - dataCallback - The callback to fire whenever data is ready to be delivered to or from the device. - - stopCallback - The callback to fire whenever the device has stopped, either explicitly via `ma_device_stop()`, or implicitly due to things like the device being - disconnected. - - pUserData - The user data pointer to use with the device. You can access this directly from the device object like `device.pUserData`. - - resampling.algorithm - The resampling algorithm to use when miniaudio needs to perform resampling between the rate specified by `sampleRate` and the device's native rate. The - default value is `ma_resample_algorithm_linear`, and the quality can be configured with `resampling.linear.lpfCount`. - - resampling.linear.lpfCount - The linear resampler applies a low-pass filter as part of it's procesing for anti-aliasing. This setting controls the quality of the filter. The higher - the value, the better the quality. Setting this to 0 will disable low-pass filtering altogether. The maximum value is `MA_MAX_RESAMPLER_LPF_FILTERS`. - The default value is `min(2, MA_MAX_RESAMPLER_LPF_FILTERS)`. - - playback.pDeviceID - A pointer to a `ma_device_id` structure containing the ID of the playback device to initialize. Setting this NULL (default) will use the system's - default playback device. Retrieve the device ID from the `ma_device_info` structure, which can be retrieved using device enumeration. - - playback.format - The sample format to use for playback. When set to `ma_format_unknown` the device's native format will be used. This can be retrieved after - initialization from the device object directly with `device.playback.format`. - - playback.channels - The number of channels to use for playback. When set to 0 the device's native channel count will be used. This can be retrieved after initialization - from the device object directly with `device.playback.channels`. - - playback.channelMap - The channel map to use for playback. When left empty, the device's native channel map will be used. This can be retrieved after initialization from the - device object direct with `device.playback.channelMap`. - - playback.shareMode - The preferred share mode to use for playback. Can be either `ma_share_mode_shared` (default) or `ma_share_mode_exclusive`. Note that if you specify - exclusive mode, but it's not supported by the backend, initialization will fail. You can then fall back to shared mode if desired. - - playback.pDeviceID - A pointer to a `ma_device_id` structure containing the ID of the playback device to initialize. Setting this NULL (default) will use the system's - default playback device. Retrieve the device ID from the `ma_device_info` structure, which can be retrieved using device enumeration. - - capture.format - The sample format to use for capture. When set to `ma_format_unknown` the device's native format will be used. This can be retrieved after - initialization from the device object directly with `device.capture.format`. - - capture.channels - The number of channels to use for capture. When set to 0 the device's native channel count will be used. This can be retrieved after initialization - from the device object directly with `device.capture.channels`. - - capture.channelMap - The channel map to use for capture. When left empty, the device's native channel map will be used. This can be retrieved after initialization from the - device object direct with `device.capture.channelMap`. - - capture.shareMode - The preferred share mode to use for capture. Can be either `ma_share_mode_shared` (default) or `ma_share_mode_exclusive`. Note that if you specify - exclusive mode, but it's not supported by the backend, initialization will fail. You can then fall back to shared mode if desired. - - wasapi.noAutoConvertSRC - WASAPI only. When set to true, disables WASAPI's automatic resampling and forces the use of miniaudio's resampler. Defaults to false. - - wasapi.noDefaultQualitySRC - WASAPI only. Only used when `wasapi.noAutoConvertSRC` is set to false. When set to true, disables the use of `AUDCLNT_STREAMFLAGS_SRC_DEFAULT_QUALITY`. - You should usually leave this set to false, which is the default. - - wasapi.noAutoStreamRouting - WASAPI only. When set to true, disables automatic stream routing on the WASAPI backend. Defaults to false. - - wasapi.noHardwareOffloading - WASAPI only. When set to true, disables the use of WASAPI's hardware offloading feature. Defaults to false. - - alsa.noMMap - ALSA only. When set to true, disables MMap mode. Defaults to false. - - pulse.pStreamNamePlayback - PulseAudio only. Sets the stream name for playback. - - pulse.pStreamNameCapture - PulseAudio only. Sets the stream name for capture. - - -Once initialized, the device's config is immutable. If you need to change the config you will need to initialize a new device. - -If both `periodSizeInFrames` and `periodSizeInMilliseconds` are set to zero, it will default to `MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_LOW_LATENCY` or -`MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_CONSERVATIVE`, depending on whether or not `performanceProfile` is set to `ma_performance_profile_low_latency` or -`ma_performance_profile_conservative`. - -If you request exclusive mode and the backend does not support it an error will be returned. For robustness, you may want to first try initializing the device -in exclusive mode, and then fall back to shared mode if required. Alternatively you can just request shared mode (the default if you leave it unset in the -config) which is the most reliable option. Some backends do not have a practical way of choosing whether or not the device should be exclusive or not (ALSA, -for example) in which case it just acts as a hint. Unless you have special requirements you should try avoiding exclusive mode as it's intrusive to the user. -Starting with Windows 10, miniaudio will use low-latency shared mode where possible which may make exclusive mode unnecessary. - -After initializing the device it will be in a stopped state. To start it, use `ma_device_start()`. - -When sending or receiving data to/from a device, miniaudio will internally perform a format conversion to convert between the format specified by pConfig and -the format used internally by the backend. If you pass in 0 for the sample format, channel count, sample rate _and_ channel map, data transmission will run on -an optimized pass-through fast path. You can retrieve the format, channel count and sample rate by inspecting the `playback/capture.format`, -`playback/capture.channels` and `sampleRate` members of the device object. - -When compiling for UWP you must ensure you call this function on the main UI thread because the operating system may need to present the user with a message -asking for permissions. Please refer to the official documentation for ActivateAudioInterfaceAsync() for more information. - -ALSA Specific: When initializing the default device, requesting shared mode will try using the "dmix" device for playback and the "dsnoop" device for capture. -If these fail it will try falling back to the "hw" device. - - -Example 1 - Simple Initialization ---------------------------------- -This example shows how to initialize a simple playback default using a standard configuration. If you are just needing to do simple playback from the default -playback device this is usually all you need. - -```c -ma_device_config config = ma_device_config_init(ma_device_type_playback); -config.playback.format = ma_format_f32; -config.playback.channels = 2; -config.sampleRate = 48000; -config.dataCallback = ma_data_callback; -config.pMyUserData = pMyUserData; - -ma_device device; -ma_result result = ma_device_init(NULL, &config, &device); -if (result != MA_SUCCESS) { - // Error -} -``` - - -Example 2 - Advanced Initialization ------------------------------------ -This example show how you might do some more advanced initialization.

For my own purposes, and for anybody out there whose -needing to figure out how this darn thing works, I'm going to outline a few things here. - -Since miniaudio is a fairly low-level API, one of the things it needs is control over specific devices, and it needs to be -able to identify whether or not it can be used as playback and/or capture. The AudioObject API is the only one I've seen -that supports this level of detail. There was some public domain sample code I stumbled across that used the AudioComponent -and AudioUnit APIs, but I couldn't see anything that gave low-level control over device selection and capabilities (the -distinction between playback and capture in particular). Therefore, miniaudio is using the AudioObject API. - -Most (all?) functions in the AudioObject API take a AudioObjectID as it's input. This is the device identifier. When -retrieving global information, such as the device list, you use kAudioObjectSystemObject. When retrieving device-specific -data, you pass in the ID for that device. In order to retrieve device-specific IDs you need to enumerate over each of the -devices. This is done using the AudioObjectGetPropertyDataSize() and AudioObjectGetPropertyData() APIs which seem to be -the central APIs for retrieving information about the system and specific devices. - -To use the AudioObjectGetPropertyData() API you need to use the notion of a property address. A property address is a -structure with three variables and is used to identify which property you are getting or setting. The first is the "selector" -which is basically the specific property that you're wanting to retrieve or set. The second is the "scope", which is -typically set to kAudioObjectPropertyScopeGlobal, kAudioObjectPropertyScopeInput for input-specific properties and -kAudioObjectPropertyScopeOutput for output-specific properties. The last is the "element" which is always set to -kAudioObjectPropertyElementMaster in miniaudio's case. I don't know of any cases where this would be set to anything different. - -Back to the earlier issue of device retrieval, you first use the AudioObjectGetPropertyDataSize() API to retrieve the size -of the raw data which is just a list of AudioDeviceID's. You use the kAudioObjectSystemObject AudioObjectID, and a property -address with the kAudioHardwarePropertyDevices selector and the kAudioObjectPropertyScopeGlobal scope. Once you have the -size, allocate a block of memory of that size and then call AudioObjectGetPropertyData(). The data is just a list of -AudioDeviceID's so just do "dataSize/sizeof(AudioDeviceID)" to know the device count. -*/ - -static ma_result ma_result_from_OSStatus(OSStatus status) -{ - switch (status) - { - case noErr: return MA_SUCCESS;

Before I go into -detail about the major changes I would like to apologize. I know it's annoying dealing with breaking API changes, but I think -it's best to get these changes out of the way now while the library is still relatively young and unknown. - -There's been a lot of refactoring with this release so there's a good chance a few bugs have been introduced. I apologize in -advance for this. You may want to hold off on upgrading for the short term if you're worried. If mini_al v0.8.14 works for -you, and you don't need full-duplex support, you can avoid upgrading (though you won't be getting future bug fixes). - - -Rebranding to "miniaudio" -------------------------- -The decision was made to rename mini_al to miniaudio. Don't worry, it's the same project. The reason for this is simple: - -1) Having the word "audio" in the title makes it immediately clear that the library is related to audio; and -2) I don't like the look of the underscore. - -This rebrand has necessitated a change in namespace from "mal" to "ma". I know this is annoying, and I apologize, but it's -better to get this out of the road now rather than later. Also, since there are necessary API changes for full-duplex support -I think it's better to just get the namespace change over and done with at the same time as the full-duplex changes. I'm hoping -this will be the last of the major API changes. Fingers crossed! - -The implementation define is now "#define MINIAUDIO_IMPLEMENTATION". You can also use "#define MA_IMPLEMENTATION" if that's -your preference. - - -Full-Duplex Support -------------------- -The major feature added to version 0.9 is full-duplex. This has necessitated a few API changes. - -1) The data callback has now changed. Previously there was one type of callback for playback and another for capture. I wanted - to avoid a third callback just for full-duplex so the decision was made to break this API and unify the callbacks. Now, - there is just one callback which is the same for all three modes (playback, capture, duplex). The new callback looks like - the following: - - void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount); - - This callback allows you to move data straight out of the input buffer and into the output buffer in full-duplex mode. In - playback-only mode, pInput will be null. Likewise, pOutput will be null in capture-only mode. The sample count is no longer - returned from the callback since it's not necessary for miniaudio anymore. - -2) The device config needed to change in order to support full-duplex. Full-duplex requires the ability to allow the client - to choose a different PCM format for the playback and capture sides. The old ma_device_config object simply did not allow - this and needed to change. With these changes you now specify the device ID, format, channels, channel map and share mode - on a per-playback and per-capture basis (see example below). The sample rate must be the same for playback and capture. - - Since the device config API has changed I have also decided to take the opportunity to simplify device initialization. Now, - the device ID, device type and callback user data are set in the config. ma_device_init() is now simplified down to taking - just the context, device config and a pointer to the device object being initialized. The rationale for this change is that - it just makes more sense to me that these are set as part of the config like everything else. - - Example device initialization: - - ma_device_config config = ma_device_config_init(ma_device_type_duplex); // Or ma_device_type_playback or ma_device_type_capture. - config.playback.pDeviceID = &myPlaybackDeviceID; // Or NULL for the default playback device. - config.playback.format = ma_format_f32; - config.playback.channels = 2; - config.capture.pDeviceID = &myCaptureDeviceID; // Or NULL for the default capture device. - config.capture.format = ma_format_s16; - config.capture.channels = 1; - config.sampleRate = 44100; - config.dataCallback = data_callback; - config.pUserData = &myUserData; - - result = ma_device_init(&myContext, &config, &device); - if (result != MA_SUCCESS) { - ... handle error ... - } - - Note that the "onDataCallback" member of ma_device_config has been renamed to "dataCallback". Also, "onStopCallback" has - been renamed to "stopCallback". - -This is the first pass for full-duplex and there is a known bug. You will hear crackling on the following backends when sample -rate conversion is required for the playback device: - - Core Audio - - JACK - - AAudio - - OpenSL - - WebAudio - -In addition to the above, not all platforms have been absolutely thoroughly tested simply because I lack the hardware for such -thorough testing. If you experience a bug, an issue report on GitHub or an email would be greatly appreciated (and a sample -program that reproduces the issue if possible). - - -Other API Changes ------------------ -In addition to the above, the following API changes have been made: - -- The log callback is no longer passed to ma_context_config_init(). Instead you need to set it manually after initialization. -- The onLogCallback member of ma_context_config has been renamed to "logCallback". -- The log callback now takes a logLevel parameter. The new callback looks like: void log_callback(ma_context* pContext, ma_device* pDevice, ma_uint32 logLevel, const char* message) - - You can use ma_log_level_to_string() to convert the logLevel to human readable text if you want to log it. -- Some APIs have been renamed: - - mal_decoder_read() -> ma_decoder_read_pcm_frames() - - mal_decoder_seek_to_frame() -> ma_decoder_seek_to_pcm_frame() - - mal_sine_wave_read() -> ma_sine_wave_read_f32() - - mal_sine_wave_read_ex() -> ma_sine_wave_read_f32_ex() -- Some APIs have been removed: - - mal_device_get_buffer_size_in_bytes() - - mal_device_set_recv_callback() - - mal_device_set_send_callback() - - mal_src_set_input_sample_rate() - - mal_src_set_output_sample_rate() -- Error codes have been rearranged. If you're a binding maintainer you will need to update. -- The ma_backend enums have been rearranged to priority order. The rationale for this is to simplify automatic backend selection - and to make it easier to see the priority. If you're a binding maintainer you will need to update. -- ma_dsp has been renamed to ma_pcm_converter. The rationale for this change is that I'm expecting "ma_dsp" to conflict with - some future planned high-level APIs. -- For functions that take a pointer/count combo, such as ma_decoder_read_pcm_frames(), the parameter order has changed so that - the pointer comes before the count. The rationale for this is to keep it consistent with things like memcpy(). - - -Miscellaneous Changes ---------------------- -The following miscellaneous changes have also been made. - -- The AAudio backend has been added for Android 8 and above. This is Android's new "High-Performance Audio" API. (For the - record, this is one of the nicest audio APIs out there, just behind the BSD audio APIs). -- The WebAudio backend has been added. This is based on ScriptProcessorNode. This removes the need for SDL. -- The SDL and OpenAL backends have been removed. These were originally implemented to add support for platforms for which miniaudio - was not explicitly supported. These are no longer needed and have therefore been removed. -- Device initialization now fails if the requested share mode is not supported. If you ask for exclusive mode, you either get an - exclusive mode device, or an error. The rationale for this change is to give the client more control over how to handle cases - when the desired shared mode is unavailable. -- A lock-free ring buffer API has been added. There are two varients of this. "ma_rb" operates on bytes, whereas "ma_pcm_rb" - operates on PCM frames. -- The library is now licensed as a choice of Public Domain (Unlicense) _or_ MIT-0 (No Attribution) which is the same as MIT, but - removes the attribution requirement. The rationale for this is to support countries that don't recognize public domain. -*/ - -/* -REVISION HISTORY -================ -v0.xx.xx - 2020-xx-xx - - Fix potential crash when ma_device object's are not aligned to MA_SIMD_ALIGNMENT. - -v0.9.10 - 2020-01-15 - - Fix compilation errors due to #if/#endif mismatches. - - WASAPI: Fix a bug where automatic stream routing is being performed for devices that are initialized with an explicit device ID. - - iOS: Fix a crash on device uninitialization. - -v0.9.9 - 2020-01-09 - - Fix compilation errors with MinGW. - - Fix compilation errors when compiling on Apple platforms. - - WASAPI: Add support for disabling hardware offloading. - - WASAPI: Add support for disabling automatic stream routing. - - Core Audio: Fix bugs in the case where the internal device uses deinterleaved buffers. - - Core Audio: Add support for controlling the session category (AVAudioSessionCategory) and options (AVAudioSessionCategoryOptions). - - JACK: Fix bug where incorrect ports are connected. - -v0.9.8 - 2019-10-07 - - WASAPI: Fix a potential deadlock when starting a full-duplex device. - - WASAPI: Enable automatic resampling by default.

By default it will be initialized to zero, but this can be changed by setting noPreZeroedOutputBuffer in the device - config. Setting noPreZeroedOutputBuffer to true will leave the contents undefined. - - Add support for clipping samples after the data callback has returned. This only applies when the playback sample format is - configured as ma_format_f32. If you are doing clipping yourself, you can disable this overhead by setting noClip to true in - the device config. - - Add support for master volume control for devices. - - Use ma_device_set_master_volume() to set the volume to a factor between 0 and 1, where 0 is silence and 1 is full volume. - - Use ma_device_set_master_gain_db() to set the volume in decibels where 0 is full volume and < 0 reduces the volume. - - Fix warnings emitted by GCC when `__inline__` is undefined or defined as nothing. - -v0.9.7 - 2019-08-28 - - Add support for loopback mode (WASAPI only). - - To use this, set the device type to ma_device_type_loopback, and then fill out the capture section of the device config. - - If you need to capture from a specific output device, set the capture device ID to that of a playback device. - - Fix a crash when an error is posted in ma_device_init(). - - Fix a compilation error when compiling for ARM architectures. - - Fix a bug with the audio(4) backend where the device is incorrectly being opened in non-blocking mode. - - Fix memory leaks in the Core Audio backend. - - Minor refactoring to the WinMM, ALSA, PulseAudio, OSS, audio(4), sndio and null backends. - -v0.9.6 - 2019-08-04 - - Add support for loading decoders using a wchar_t string for file paths. - - Don't trigger an assert when ma_device_start() is called on a device that is already started. This will now log a warning - and return MA_INVALID_OPERATION. The same applies for ma_device_stop(). - - Try fixing an issue with PulseAudio taking a long time to start playback. - - Fix a bug in ma_convert_frames() and ma_convert_frames_ex(). - - Fix memory leaks in the WASAPI backend. - - Fix a compilation error with Visual Studio 2010. - -v0.9.5 - 2019-05-21 - - Add logging to ma_dlopen() and ma_dlsym(). - - Add ma_decoder_get_length_in_pcm_frames(). - - Fix a bug with capture on the OpenSL|ES backend. - - Fix a bug with the ALSA backend where a device would not restart after being stopped. - -v0.9.4 - 2019-05-06 - - Add support for C89. With this change, miniaudio should compile clean with GCC/Clang with "-std=c89 -ansi -pedantic" and - Microsoft compilers back to VC6. Other compilers should also work, but have not been tested. - -v0.9.3 - 2019-04-19 - - Fix compiler errors on GCC when compiling with -std=c99. - -v0.9.2 - 2019-04-08 - - Add support for per-context user data. - - Fix a potential bug with context configs. - - Fix some bugs with PulseAudio. - -v0.9.1 - 2019-03-17 - - Fix a bug where the output buffer is not getting zeroed out before calling the data callback. This happens when - the device is running in passthrough mode (not doing any data conversion). - - Fix an issue where the data callback is getting called too frequently on the WASAPI and DirectSound backends. - - Fix error on the UWP build. - - Fix a build error on Apple platforms. - -v0.9 - 2019-03-06 - - Rebranded to "miniaudio". All namespaces have been renamed from "mal" to "ma". - - API CHANGE: ma_device_init() and ma_device_config_init() have changed significantly: - - The device type, device ID and user data pointer have moved from ma_device_init() to the config. - - All variations of ma_device_config_init_*() have been removed in favor of just ma_device_config_init(). - - ma_device_config_init() now takes only one parameter which is the device type. All other properties need - to be set on the returned object directly. - - The onDataCallback and onStopCallback members of ma_device_config have been renamed to "dataCallback" - and "stopCallback". - - The ID of the physical device is now split into two: one for the playback device and the other for the - capture device. This is required for full-duplex. These are named "pPlaybackDeviceID" and "pCaptureDeviceID". - - API CHANGE: The data callback has changed. It now uses a unified callback for all device types rather than - being separate for each. It now takes two pointers - one containing input data and the other output data. This - design in required for full-duplex. The return value is now void instead of the number of frames written. The - new callback looks like the following: - void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount); - - API CHANGE: Remove the log callback parameter from ma_context_config_init(). With this change, - ma_context_config_init() now takes no parameters and the log callback is set via the structure directly. The - new policy for config initialization is that only mandatory settings are passed in to *_config_init(). The - "onLog" member of ma_context_config has been renamed to "logCallback". - - API CHANGE: Remove ma_device_get_buffer_size_in_bytes(). - - API CHANGE: Rename decoding APIs to "pcm_frames" convention. - - mal_decoder_read() -> ma_decoder_read_pcm_frames() - - mal_decoder_seek_to_frame() -> ma_decoder_seek_to_pcm_frame() - - API CHANGE: Rename sine wave reading APIs to f32 convention. - - mal_sine_wave_read() -> ma_sine_wave_read_f32() - - mal_sine_wave_read_ex() -> ma_sine_wave_read_f32_ex() - - API CHANGE: Remove some deprecated APIs - - mal_device_set_recv_callback() - - mal_device_set_send_callback() - - mal_src_set_input_sample_rate() - - mal_src_set_output_sample_rate() - - API CHANGE: Add log level to the log callback. New signature: - - void on_log(ma_context* pContext, ma_device* pDevice, ma_uint32 logLevel, const char* message) - - API CHANGE: Changes to result codes. Constants have changed and unused codes have been removed. If you're - a binding mainainer you will need to update your result code constants. - - API CHANGE: Change the order of the ma_backend enums to priority order. If you are a binding maintainer, you - will need to update. - - API CHANGE: Rename mal_dsp to ma_pcm_converter. All functions have been renamed from mal_dsp_*() to - ma_pcm_converter_*(). All structures have been renamed from mal_dsp* to ma_pcm_converter*. - - API CHANGE: Reorder parameters of ma_decoder_read_pcm_frames() to be consistent with the new parameter order scheme. - - The resampling algorithm has been changed from sinc to linear. The rationale for this is that the sinc implementation - is too inefficient right now. This will hopefully be improved at a later date. - - Device initialization will no longer fall back to shared mode if exclusive mode is requested but is unusable. - With this change, if you request an device in exclusive mode, but exclusive mode is not supported, it will not - automatically fall back to shared mode. The client will need to reinitialize the device in shared mode if that's - what they want. - - Add ring buffer API. This is ma_rb and ma_pcm_rb, the difference being that ma_rb operates on bytes and - ma_pcm_rb operates on PCM frames. - - Add Web Audio backend. This is used when compiling with Emscripten. The SDL backend, which was previously - used for web support, will be removed in a future version. - - Add AAudio backend (Android Audio). This is the new priority backend for Android. Support for AAudio starts - with Android 8. OpenSL|ES is used as a fallback for older versions of Android. - - Remove OpenAL and SDL backends. - - Fix a possible deadlock when rapidly stopping the device after it has started. - - Update documentation. - - Change licensing to a choice of public domain _or_ MIT-0 (No Attribution). - -v0.8.14 - 2018-12-16 - - Core Audio: Fix a bug where the device state is not set correctly after stopping. - - Add support for custom weights to the channel router. - - Update decoders to use updated APIs in dr_flac, dr_mp3 and dr_wav. - -v0.8.13 - 2018-12-04 - - Core Audio: Fix a bug with channel mapping. - - Fix a bug with channel routing where the back/left and back/right channels have the wrong weight. - -v0.8.12 - 2018-11-27 - - Drop support for SDL 1.2.

Note that this is still in the - early stages and not all backends handle this the same way. As of this version, this will not detect a default - device switch when changed from the operating system's audio preferences (unless the backend itself handles - this automatically). This is not supported in exclusive mode. - - WASAPI and Core Audio: Add support for stream routing. When the application is using a default device and the - user switches the default device via the operating system's audio preferences, miniaudio will automatically switch - the internal device to the new default. This is not supported in exclusive mode. - - WASAPI: Add support for hardware offloading via IAudioClient2. Only supported on Windows 8 and newer. - - WASAPI: Add support for low-latency shared mode via IAudioClient3. Only supported on Windows 10 and newer. - - Add support for compiling the UWP build as C. - - mal_device_set_recv_callback() and mal_device_set_send_callback() have been deprecated. You must now set this - when the device is initialized with mal_device_init*(). These will be removed in version 0.9.0. - -v0.8.5 - 2018-08-12 - - Add support for specifying the size of a device's buffer in milliseconds. You can still set the buffer size in - frames if that suits you. When bufferSizeInFrames is 0, bufferSizeInMilliseconds will be used. If both are non-0 - then bufferSizeInFrames will take priority. If both are set to 0 the default buffer size is used. - - Add support for the audio(4) backend to OpenBSD. - - Fix a bug with the ALSA backend that was causing problems on Raspberry Pi. This significantly improves the - Raspberry Pi experience. - - Fix a bug where an incorrect number of samples is returned from sinc resampling. - - Add support for setting the value to be passed to internal calls to CoInitializeEx(). - - WASAPI and WinMM: Stop the device when it is unplugged. - -v0.8.4 - 2018-08-06 - - Add sndio backend for OpenBSD. - - Add audio(4) backend for NetBSD. - - Drop support for the OSS backend on everything except FreeBSD and DragonFly BSD. - - Formats are now native-endian (were previously little-endian). - - Mark some APIs as deprecated: - - mal_src_set_input_sample_rate() and mal_src_set_output_sample_rate() are replaced with mal_src_set_sample_rate(). - - mal_dsp_set_input_sample_rate() and mal_dsp_set_output_sample_rate() are replaced with mal_dsp_set_sample_rate(). - - Fix a bug when capturing using the WASAPI backend. - - Fix some aliasing issues with resampling, specifically when increasing the sample rate. - - Fix warnings. - -v0.8.3 - 2018-07-15 - - Fix a crackling bug when resampling in capture mode. - - Core Audio: Fix a bug where capture does not work. - - ALSA: Fix a bug where the worker thread can get stuck in an infinite loop. - - PulseAudio: Fix a bug where mal_context_init() succeeds when PulseAudio is unusable. - - JACK: Fix a bug where mal_context_init() succeeds when JACK is unusable. - -v0.8.2 - 2018-07-07 - - Fix a bug on macOS with Core Audio where the internal callback is not called. - -v0.8.1 - 2018-07-06 - - Fix compilation errors and warnings. - -v0.8 - 2018-07-05 - - Changed MAL_IMPLEMENTATION to MINI_AL_IMPLEMENTATION for consistency with other libraries. The old - way is still supported for now, but you should update as it may be removed in the future. - - API CHANGE: Replace device enumeration APIs. mal_enumerate_devices() has been replaced with - mal_context_get_devices(). An additional low-level device enumration API has been introduced called - mal_context_enumerate_devices() which uses a callback to report devices. - - API CHANGE: Rename mal_get_sample_size_in_bytes() to mal_get_bytes_per_sample() and add - mal_get_bytes_per_frame(). - - API CHANGE: Replace mal_device_config.preferExclusiveMode with mal_device_config.shareMode. - - This new config can be set to mal_share_mode_shared (default) or mal_share_mode_exclusive. - - API CHANGE: Remove excludeNullDevice from mal_context_config.alsa. - - API CHANGE: Rename MAL_MAX_SAMPLE_SIZE_IN_BYTES to MAL_MAX_PCM_SAMPLE_SIZE_IN_BYTES. - - API CHANGE: Change the default channel mapping to the standard Microsoft mapping. - - API CHANGE: Remove backend-specific result codes. - - API CHANGE: Changes to the format conversion APIs (mal_pcm_f32_to_s16(), etc.) - - Add support for Core Audio (Apple). - - Add support for PulseAudio. - - This is the highest priority backend on Linux (higher priority than ALSA) since it is commonly - installed by default on many of the popular distros and offer's more seamless integration on - platforms where PulseAudio is used. In addition, if PulseAudio is installed and running (which - is extremely common), it's better to just use PulseAudio directly rather than going through the - "pulse" ALSA plugin (which is what the "default" ALSA device is likely set to). - - Add support for JACK. - - Remove dependency on asound.h for the ALSA backend. This means the ALSA development packages are no - longer required to build miniaudio. - - Remove dependency on dsound.h for the DirectSound backend. This fixes build issues with some - distributions of MinGW. - - Remove dependency on audioclient.h for the WASAPI backend. This fixes build issues with some - distributions of MinGW. - - Add support for dithering to format conversion. - - Add support for configuring the priority of the worker thread. - - Add a sine wave generator. - - Improve efficiency of sample rate conversion. - - Introduce the notion of standard channel maps. Use mal_get_standard_channel_map(). - - Introduce the notion of default device configurations. A default config uses the same configuration - as the backend's internal device, and as such results in a pass-through data transmission pipeline. - - Add support for passing in NULL for the device config in mal_device_init(), which uses a default - config. This requires manually calling mal_device_set_send/recv_callback(). - - Add support for decoding from raw PCM data (mal_decoder_init_raw(), etc.) - - Make mal_device_init_ex() more robust. - - Make some APIs more const-correct. - - Fix errors with SDL detection on Apple platforms. - - Fix errors with OpenAL detection. - - Fix some memory leaks. - - Fix a bug with opening decoders from memory. - - Early work on SSE2, AVX2 and NEON optimizations. - - Miscellaneous bug fixes. - - Documentation updates. - -v0.7 - 2018-02-25 - - API CHANGE: Change mal_src_read_frames() and mal_dsp_read_frames() to use 64-bit sample counts. - - Add decoder APIs for loading WAV, FLAC, Vorbis and MP3 files. - - Allow opening of devices without a context. - - In this case the context is created and managed internally by the device. - - Change the default channel mapping to the same as that used by FLAC. - - Fix build errors with macOS. - -v0.6c - 2018-02-12 - - Fix build errors with BSD/OSS. - -v0.6b - 2018-02-03 - - Fix some warnings when compiling with Visual C++. - -v0.6a - 2018-01-26 - - Fix errors with channel mixing when increasing the channel count. - - Improvements to the build system for the OpenAL backend. - - Documentation fixes. - -v0.6 - 2017-12-08 - - API CHANGE: Expose and improve mutex APIs. If you were using the mutex APIs before this version you'll - need to update. - - API CHANGE: SRC and DSP callbacks now take a pointer to a mal_src and mal_dsp object respectively. - - API CHANGE: Improvements to event and thread APIs. These changes make these APIs more consistent. - - Add support for SDL and Emscripten. - - Simplify the build system further for when development packages for various backends are not installed. - With this change, when the compiler supports __has_include, backends without the relevant development - packages installed will be ignored. This fixes the build for old versions of MinGW. - - Fixes to the Android build. - - Add mal_convert_frames(). This is a high-level helper API for performing a one-time, bulk conversion of - audio data to a different format. - - Improvements to f32 -> u8/s16/s24/s32 conversion routines. - - Fix a bug where the wrong value is returned from mal_device_start() for the OpenSL backend. - - Fixes and improvements for Raspberry Pi. - - Warning fixes. - -v0.5 - 2017-11-11 - - API CHANGE: The mal_context_init() function now takes a pointer to a mal_context_config object for - configuring the context. The works in the same kind of way as the device config. The rationale for this - change is to give applications better control over context-level properties, add support for backend- - specific configurations, and support extensibility without breaking the API. - - API CHANGE: The alsa.preferPlugHW device config variable has been removed since it's not really useful for - anything anymore. - - ALSA: By default, device enumeration will now only enumerate over unique card/device pairs. Applications - can enable verbose device enumeration by setting the alsa.useVerboseDeviceEnumeration context config - variable. - - ALSA: When opening a device in shared mode (the default), the dmix/dsnoop plugin will be prioritized. If - this fails it will fall back to the hw plugin. With this change the preferExclusiveMode config is now - honored. Note that this does not happen when alsa.useVerboseDeviceEnumeration is set to true (see above) - which is by design. - - ALSA: Add support for excluding the "null" device using the alsa.excludeNullDevice context config variable. - - ALSA: Fix a bug with channel mapping which causes an assertion to fail. - - Fix errors with enumeration when pInfo is set to NULL. - - OSS: Fix a bug when starting a device when the client sends 0 samples for the initial buffer fill. - -v0.4 - 2017-11-05 - - API CHANGE: The log callback is now per-context rather than per-device and as is thus now passed to - mal_context_init(). The rationale for this change is that it allows applications to capture diagnostic - messages at the context level. Previously this was only available at the device level. - - API CHANGE: The device config passed to mal_device_init() is now const. - - Added support for OSS which enables support on BSD platforms. - - Added support for WinMM (waveOut/waveIn). - - Added support for UWP (Universal Windows Platform) applications. Currently C++ only. - - Added support for exclusive mode for selected backends. Currently supported on WASAPI. - - POSIX builds no longer require explicit linking to libpthread (-lpthread). - - ALSA: Explicit linking to libasound (-lasound) is no longer required. - - ALSA: Latency improvements. - - ALSA: Use MMAP mode where available. This can be disabled with the alsa.noMMap config. - - ALSA: Use "hw" devices instead of "plughw" devices by default. This can be disabled with the - alsa.preferPlugHW config. - - WASAPI is now the highest priority backend on Windows platforms. - - Fixed an error with sample rate conversion which was causing crackling when capturing. - - Improved error handling. - - Improved compiler support. - - Miscellaneous bug fixes. - -v0.3 - 2017-06-19 - - API CHANGE: Introduced the notion of a context. The context is the highest level object and is required for - enumerating and creating devices. Now, applications must first create a context, and then use that to - enumerate and create devices. The reason for this change is to ensure device enumeration and creation is - tied to the same backend. In addition, some backends are better suited to this design. - - API CHANGE: Removed the rewinding APIs because they're too inconsistent across the different backends, hard - to test and maintain, and just generally unreliable. - - Added helper APIs for initializing mal_device_config objects. - - Null Backend: Fixed a crash when recording. - - Fixed build for UWP. - - Added support for f32 formats to the OpenSL|ES backend. - - Added initial implementation of the WASAPI backend. - - Added initial implementation of the OpenAL backend. - - Added support for low quality linear sample rate conversion. - - Added early support for basic channel mapping. - -v0.2 - 2016-10-28 - - API CHANGE: Add user data pointer as the last parameter to mal_device_init(). The rationale for this - change is to ensure the logging callback has access to the user data during initialization. - - API CHANGE: Have device configuration properties be passed to mal_device_init() via a structure. Rationale: - 1) The number of parameters is just getting too much. - 2) It makes it a bit easier to add new configuration properties in the future. In particular, there's a - chance there will be support added for backend-specific properties. - - Dropped support for f64, A-law and Mu-law formats since they just aren't common enough to justify the - added maintenance cost. - - DirectSound: Increased the default buffer size for capture devices. - - Added initial implementation of the OpenSL|ES backend. - -v0.1 - 2016-10-21 - - Initial versioned release. -*/ - - -/* -This software is available as a choice of the following licenses.

(It does at least use delta encoding - only the changed portions of each -* frame are saved.) -* -* So resulting files are often quite large. The hope is that it will be handy nonetheless -* as a quick and easily-integrated way for programs to spit out animations. -* -* Only RGBA8 is currently supported as an input format. (The alpha is ignored.) -* -* CONFIGURATION: -* -* #define RGIF_IMPLEMENTATION -* Generates the implementation of the library into the included file. -* If not defined, the library is in header only mode and can be included in other headers -* or source files without problems. But only ONE file should hold the implementation. -* -* USAGE: -* 1) Create a GifWriter struct. Pass it to GifBegin() to initialize and write the header. -* 2) Pass subsequent frames to GifWriteFrame(). -* 3) Finally, call GifEnd() to close the file handle and free memory. -* -* -* LICENSE: This software is available under 2 licenses -- choose whichever you prefer -* -* ALTERNATIVE A - MIT License -* -* Copyright (c) 2017-2019 Ramon Santamaria (@raysan5) -* -* Permission is hereby granted, free of charge, to any person obtaining a copy of -* this software and associated documentation files (the "Software"), to deal in -* the Software without restriction, including without limitation the rights to -* use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies -* of the Software, and to permit persons to whom the Software is furnished to do -* so, subject to the following conditions: -* -* The above copyright notice and this permission notice shall be included in all -* copies or substantial portions of the Software. -* -* THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR -* IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, -* FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

Data read from callbacks are processed -// through a small internal buffer (currently 128 bytes) to try to reduce -// overhead. -// -// The three functions you must define are "read" (reads some bytes of data), -// "skip" (skips some bytes of data), "eof" (reports if the stream is at the end). -// -// =========================================================================== -// -// SIMD support -// -// The JPEG decoder will try to automatically use SIMD kernels on x86 when -// supported by the compiler. For ARM Neon support, you must explicitly -// request it. -// -// (The old do-it-yourself SIMD API is no longer supported in the current -// code.) -// -// On x86, SSE2 will automatically be used when available based on a run-time -// test; if not, the generic C versions are used as a fall-back. On ARM targets, -// the typical path is to have separate builds for NEON and non-NEON devices -// (at least this is true for iOS and Android). Therefore, the NEON support is -// toggled by a build flag: define STBI_NEON to get NEON loops. -// -// If for some reason you do not want to use any of SIMD code, or if -// you have issues compiling it, you can disable it entirely by -// defining STBI_NO_SIMD. -// -// =========================================================================== -// -// HDR image support (disable by defining STBI_NO_HDR) -// -// stb_image supports loading HDR images in general, and currently the Radiance -// .HDR file format specifically. You can still load any file through the existing -// interface; if you attempt to load an HDR file, it will be automatically remapped -// to LDR, assuming gamma 2.2 and an arbitrary scale factor defaulting to 1; -// both of these constants can be reconfigured through this interface: -// -// stbi_hdr_to_ldr_gamma(2.2f); -// stbi_hdr_to_ldr_scale(1.0f); -// -// (note, do not use _inverse_ constants; stbi_image will invert them -// appropriately). -// -// Additionally, there is a new, parallel interface for loading files as -// (linear) floats to preserve the full dynamic range: -// -// float *data = stbi_loadf(filename, &x, &y, &n, 0); -// -// If you load LDR images through this interface, those images will -// be promoted to floating point values, run through the inverse of -// constants corresponding to the above: -// -// stbi_ldr_to_hdr_scale(1.0f); -// stbi_ldr_to_hdr_gamma(2.2f); -// -// Finally, given a filename (or an open file or memory block--see header -// file for details) containing image data, you can query for the "most -// appropriate" interface to use (that is, whether the image is HDR or -// not), using: -// -// stbi_is_hdr(char *filename); -// -// =========================================================================== -// -// iPhone PNG support: -// -// By default we convert iphone-formatted PNGs back to RGB, even though -// they are internally encoded differently. You can disable this conversion -// by calling stbi_convert_iphone_png_to_rgb(0), in which case -// you will always just get the native iphone "format" through (which -// is BGR stored in RGB). -// -// Call stbi_set_unpremultiply_on_load(1) as well to force a divide per -// pixel to remove any premultiplied alpha *only* if the image file explicitly -// says there's premultiplied data (currently only happens in iPhone images, -// and only if iPhone convert-to-rgb processing is on). -// -// =========================================================================== -// -// ADDITIONAL CONFIGURATION -// -// - You can suppress implementation of any of the decoders to reduce -// your code footprint by #defining one or more of the following -// symbols before creating the implementation. -// -// STBI_NO_JPEG -// STBI_NO_PNG -// STBI_NO_BMP -// STBI_NO_PSD -// STBI_NO_TGA -// STBI_NO_GIF -// STBI_NO_HDR -// STBI_NO_PIC -// STBI_NO_PNM (.ppm and .pgm) -// -// - You can request *only* certain decoders and suppress all other ones -// (this will be more forward-compatible, as addition of new decoders -// doesn't require you to disable them explicitly): -// -// STBI_ONLY_JPEG -// STBI_ONLY_PNG -// STBI_ONLY_BMP -// STBI_ONLY_PSD -// STBI_ONLY_TGA -// STBI_ONLY_GIF -// STBI_ONLY_HDR -// STBI_ONLY_PIC -// STBI_ONLY_PNM (.ppm and .pgm) -// -// - If you use STBI_NO_PNG (or _ONLY_ without PNG), and you still -// want the zlib decoder to be available, #define STBI_SUPPORT_ZLIB -// - - -#ifndef STBI_NO_STDIO -#include -#endif // STBI_NO_STDIO - -#define STBI_VERSION 1 - -enum -{ - STBI_default = 0, // only used for desired_channels - - STBI_grey = 1, - STBI_grey_alpha = 2, - STBI_rgb = 3, - STBI_rgb_alpha = 4 -};

If you do not have - IEEE floating point, define STBIR_NON_IEEE_FLOAT. This will use - a slower implementation. - - MEMORY ALLOCATION - The resize functions here perform a single memory allocation using - malloc. To control the memory allocation, before the #include that - triggers the implementation, do: - - #define STBIR_MALLOC(size,context) ... - #define STBIR_FREE(ptr,context) ... - - Each resize function makes exactly one call to malloc/free, so to use - temp memory, store the temp memory in the context and return that. - - ASSERT - Define STBIR_ASSERT(boolval) to override assert() and not use assert.h - - OPTIMIZATION - Define STBIR_SATURATE_INT to compute clamp values in-range using - integer operations instead of float operations. This may be faster - on some platforms. - - DEFAULT FILTERS - For functions which don't provide explicit control over what filters - to use, you can change the compile-time defaults with - - #define STBIR_DEFAULT_FILTER_UPSAMPLE STBIR_FILTER_something - #define STBIR_DEFAULT_FILTER_DOWNSAMPLE STBIR_FILTER_something - - See stbir_filter in the header-file section for the list of filters. - - NEW FILTERS - A number of 1D filter kernels are used. For a list of - supported filters see the stbir_filter enum. To add a new filter, - write a filter function and add it to stbir__filter_info_table. - - PROGRESS - For interactive use with slow resize operations, you can install - a progress-report callback: - - #define STBIR_PROGRESS_REPORT(val) some_func(val) - - The parameter val is a float which goes from 0 to 1 as progress is made. - - For example: - - static void my_progress_report(float progress); - #define STBIR_PROGRESS_REPORT(val) my_progress_report(val) - - #define STB_IMAGE_RESIZE_IMPLEMENTATION - #include "stb_image_resize.h" - - static void my_progress_report(float progress) - { - printf("Progress: %f%%\n", progress*100); - } - - MAX CHANNELS - If your image has more than 64 channels, define STBIR_MAX_CHANNELS - to the max you'll have. - - ALPHA CHANNEL - Most of the resizing functions provide the ability to control how - the alpha channel of an image is processed. The important things - to know about this: - - 1. The best mathematically-behaved version of alpha to use is - called "premultiplied alpha", in which the other color channels - have had the alpha value multiplied in. If you use premultiplied - alpha, linear filtering (such as image resampling done by this - library, or performed in texture units on GPUs) does the "right - thing". While premultiplied alpha is standard in the movie CGI - industry, it is still uncommon in the videogame/real-time world. - - If you linearly filter non-premultiplied alpha, strange effects - occur. (For example, the 50/50 average of 99% transparent bright green - and 1% transparent black produces 50% transparent dark green when - non-premultiplied, whereas premultiplied it produces 50% - transparent near-black. The former introduces green energy - that doesn't exist in the source image.) - - 2. Artists should not edit premultiplied-alpha images; artists - want non-premultiplied alpha images. Thus, art tools generally output - non-premultiplied alpha images. - - 3. You will get best results in most cases by converting images - to premultiplied alpha before processing them mathematically. - - 4. If you pass the flag STBIR_FLAG_ALPHA_PREMULTIPLIED, the - resizer does not do anything special for the alpha channel; - it is resampled identically to other channels. This produces - the correct results for premultiplied-alpha images, but produces - less-than-ideal results for non-premultiplied-alpha images. - - 5. If you do not pass the flag STBIR_FLAG_ALPHA_PREMULTIPLIED, - then the resizer weights the contribution of input pixels - based on their alpha values, or, equivalently, it multiplies - the alpha value into the color channels, resamples, then divides - by the resultant alpha value. Input pixels which have alpha=0 do - not contribute at all to output pixels unless _all_ of the input - pixels affecting that output pixel have alpha=0, in which case - the result for that pixel is the same as it would be without - STBIR_FLAG_ALPHA_PREMULTIPLIED. However, this is only true for - input images in integer formats. For input images in float format, - input pixels with alpha=0 have no effect, and output pixels - which have alpha=0 will be 0 in all channels. (For float images, - you can manually achieve the same result by adding a tiny epsilon - value to the alpha channel of every image, and then subtracting - or clamping it at the end.) - - 6. You can suppress the behavior described in #5 and make - all-0-alpha pixels have 0 in all channels by #defining - STBIR_NO_ALPHA_EPSILON. - - 7. You can separately control whether the alpha channel is - interpreted as linear or affected by the colorspace. By default - it is linear; you almost never want to apply the colorspace. - (For example, graphics hardware does not apply sRGB conversion - to the alpha channel.) - - CONTRIBUTORS - Jorge L Rodriguez: Implementation - Sean Barrett: API design, optimizations - Aras Pranckevicius: bugfix - Nathan Reed: warning fixes - - REVISIONS - 0.97 (2020-02-02) fixed warning - 0.96 (2019-03-04) fixed warnings - 0.95 (2017-07-23) fixed warnings - 0.94 (2017-03-18) fixed warnings - 0.93 (2017-03-03) fixed bug with certain combinations of heights - 0.92 (2017-01-02) fix integer overflow on large (>2GB) images - 0.91 (2016-04-02) fix warnings; fix handling of subpixel regions - 0.90 (2014-09-17) first released version - - LICENSE - See end of file for license information. - - TODO - Don't decode all of the image data when only processing a partial tile - Don't use full-width decode buffers when only processing a partial tile - When processing wide images, break processing into tiles so data fits in L1 cache - Installable filters? - Resize that respects alpha test coverage - (Reference code: FloatImage::alphaTestCoverage and FloatImage::scaleAlphaToCoverage: - https://code.google.com/p/nvidia-texture-tools/source/browse/trunk/src/nvimage/FloatImage.cpp ) -*/ - -#ifndef STBIR_INCLUDE_STB_IMAGE_RESIZE_H -#define STBIR_INCLUDE_STB_IMAGE_RESIZE_H - -#ifdef _MSC_VER -typedef unsigned char stbir_uint8; -typedef unsigned short stbir_uint16; -typedef unsigned int stbir_uint32; -#else -#include -typedef uint8_t stbir_uint8; -typedef uint16_t stbir_uint16; -typedef uint32_t stbir_uint32; -#endif - -#ifndef STBIRDEF -#ifdef STB_IMAGE_RESIZE_STATIC -#define STBIRDEF static -#else -#ifdef __cplusplus -#define STBIRDEF extern "C" -#else -#define STBIRDEF extern -#endif -#endif -#endif - -////////////////////////////////////////////////////////////////////////////// -// -// Easy-to-use API: -// -// * "input pixels" points to an array of image data with 'num_channels' channels (e.g. RGB=3, RGBA=4) -// * input_w is input image width (x-axis), input_h is input image height (y-axis) -// * stride is the offset between successive rows of image data in memory, in bytes. you can -// specify 0 to mean packed continuously in memory -// * alpha channel is treated identically to other channels. -// * colorspace is linear or sRGB as specified by function name -// * returned result is 1 for success or 0 in case of an error. -// #define STBIR_ASSERT() to trigger an assert on parameter validation errors. -// * Memory required grows approximately linearly with input and output size, but with -// discontinuities at input_w == output_w and input_h == output_h. -// * These functions use a "default" resampling filter defined at compile time.

Call stbiw_convert_wchar_to_utf8 to convert - Windows wchar_t filenames to utf8. - -USAGE: - - There are five functions, one for each image file format: - - int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes); - int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data); - int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data); - int stbi_write_jpg(char const *filename, int w, int h, int comp, const void *data, int quality); - int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data); - - void stbi_flip_vertically_on_write(int flag); // flag is non-zero to flip data vertically - - There are also five equivalent functions that use an arbitrary write function. You are - expected to open/close your file-equivalent before and after calling these: - - int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data, int stride_in_bytes); - int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); - int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); - int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data); - int stbi_write_jpg_to_func(stbi_write_func *func, void *context, int x, int y, int comp, const void *data, int quality); - - where the callback is: - void stbi_write_func(void *context, void *data, int size); - - You can configure it with these global variables: - int stbi_write_tga_with_rle; // defaults to true; set to 0 to disable RLE - int stbi_write_png_compression_level; // defaults to 8; set to higher for more compression - int stbi_write_force_png_filter; // defaults to -1; set to 0..5 to force a filter mode - - - You can define STBI_WRITE_NO_STDIO to disable the file variant of these - functions, so the library will not use stdio.h at all. However, this will - also disable HDR writing, because it requires stdio for formatted output. - - Each function returns 0 on failure and non-0 on success. - - The functions create an image file defined by the parameters. The image - is a rectangle of pixels stored from left-to-right, top-to-bottom. - Each pixel contains 'comp' channels of data stored interleaved with 8-bits - per channel, in the following order: 1=Y, 2=YA, 3=RGB, 4=RGBA. (Y is - monochrome color.) The rectangle is 'w' pixels wide and 'h' pixels tall. - The *data pointer points to the first byte of the top-left-most pixel. - For PNG, "stride_in_bytes" is the distance in bytes from the first byte of - a row of pixels to the first byte of the next row of pixels. - - PNG creates output files with the same number of components as the input. - The BMP format expands Y to RGB in the file format and does not - output alpha. - - PNG supports writing rectangles of data even when the bytes storing rows of - data are not consecutive in memory (e.g. sub-rectangles of a larger image), - by supplying the stride between the beginning of adjacent rows. The other - formats do not. (Thus you cannot write a native-format BMP through the BMP - writer, both because it is in BGR order and because it may have padding - at the end of the line.) - - PNG allows you to set the deflate compression level by setting the global - variable 'stbi_write_png_compression_level' (it defaults to 8). - - HDR expects linear float data. Since the format is always 32-bit rgb(e) - data, alpha (if provided) is discarded, and for monochrome data it is - replicated across all three channels. - - TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed - data, set the global variable 'stbi_write_tga_with_rle' to 0. - - JPEG does ignore alpha channels in input data; quality is between 1 and 100. - Higher quality looks better but results in a bigger image. - JPEG baseline (no JPEG progressive). - -CREDITS: - - - Sean Barrett - PNG/BMP/TGA - Baldur Karlsson - HDR - Jean-Sebastien Guay - TGA monochrome - Tim Kelsey - misc enhancements - Alan Hickman - TGA RLE - Emmanuel Julien - initial file IO callback implementation - Jon Olick - original jo_jpeg.cpp code - Daniel Gibson - integrate JPEG, allow external zlib - Aarni Koskela - allow choosing PNG filter - - bugfixes: - github:Chribba - Guillaume Chereau - github:jry2 - github:romigrou - Sergio Gonzalez - Jonas Karlsson - Filip Wasil - Thatcher Ulrich - github:poppolopoppo - Patrick Boettcher - github:xeekworx - Cap Petschulat - Simon Rodriguez - Ivan Tikhonov - github:ignotion - Adam Schackart - -LICENSE - - See end of file for license information. - -*/ - -#ifndef INCLUDE_STB_IMAGE_WRITE_H -#define INCLUDE_STB_IMAGE_WRITE_H - -#include - -// if STB_IMAGE_WRITE_STATIC causes problems, try defining STBIWDEF to 'inline' or 'static inline' -#ifndef STBIWDEF -#ifdef STB_IMAGE_WRITE_STATIC -#define STBIWDEF static -#else -#ifdef __cplusplus -#define STBIWDEF extern "C" -#else -#define STBIWDEF extern -#endif -#endif -#endif - -#ifndef STB_IMAGE_WRITE_STATIC // C++ forbids static forward declarations -extern int stbi_write_tga_with_rle;

Thus, anti-aliasing of intersecting shapes may look wrong. If -// this turns out to be a problem, you can re-enable the old rasterizer with -// #define STBTT_RASTERIZER_VERSION 1 -// which will incur about a 15% speed hit. -// -// ADDITIONAL DOCUMENTATION -// -// Immediately after this block comment are a series of sample programs. -// -// After the sample programs is the "header file" section. This section -// includes documentation for each API function. -// -// Some important concepts to understand to use this library: -// -// Codepoint -// Characters are defined by unicode codepoints, e.g. 65 is -// uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is -// the hiragana for "ma". -// -// Glyph -// A visual character shape (every codepoint is rendered as -// some glyph) -// -// Glyph index -// A font-specific integer ID representing a glyph -// -// Baseline -// Glyph shapes are defined relative to a baseline, which is the -// bottom of uppercase characters. Characters extend both above -// and below the baseline. -// -// Current Point -// As you draw text to the screen, you keep track of a "current point" -// which is the origin of each character. The current point's vertical -// position is the baseline. Even "baked fonts" use this model. -// -// Vertical Font Metrics -// The vertical qualities of the font, used to vertically position -// and space the characters. See docs for stbtt_GetFontVMetrics. -// -// Font Size in Pixels or Points -// The preferred interface for specifying font sizes in stb_truetype -// is to specify how tall the font's vertical extent should be in pixels. -// If that sounds good enough, skip the next paragraph. -// -// Most font APIs instead use "points", which are a common typographic -// measurement for describing font size, defined as 72 points per inch. -// stb_truetype provides a point API for compatibility. However, true -// "per inch" conventions don't make much sense on computer displays -// since different monitors have different number of pixels per -// inch. For example, Windows traditionally uses a convention that -// there are 96 pixels per inch, thus making 'inch' measurements have -// nothing to do with inches, and thus effectively defining a point to -// be 1.333 pixels. Additionally, the TrueType font data provides -// an explicit scale factor to scale a given font's glyphs to points, -// but the author has observed that this scale factor is often wrong -// for non-commercial fonts, thus making fonts scaled in points -// according to the TrueType spec incoherently sized in practice. -// -// DETAILED USAGE: -// -// Scale: -// Select how high you want the font to be, in points or pixels. -// Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute -// a scale factor SF that will be used by all other functions. -// -// Baseline: -// You need to select a y-coordinate that is the baseline of where -// your text will appear. Call GetFontBoundingBox to get the baseline-relative -// bounding box for all characters. SF*-y0 will be the distance in pixels -// that the worst-case character could extend above the baseline, so if -// you want the top edge of characters to appear at the top of the -// screen where y=0, then you would set the baseline to SF*-y0. -// -// Current point: -// Set the current point where the first character will appear. The -// first character could extend left of the current point; this is font -// dependent. You can either choose a current point that is the leftmost -// point and hope, or add some padding, or check the bounding box or -// left-side-bearing of the first character to be displayed and set -// the current point based on that. -// -// Displaying a character: -// Compute the bounding box of the character. It will contain signed values -// relative to . I.e. if it returns x0,y0,x1,y1, -// then the character should be displayed in the rectangle from -// to = 32 && *text < 128) { - stbtt_aligned_quad q; - stbtt_GetBakedQuad(cdata, 512,512, *text-32, &x,&y,&q,1);//1=opengl & d3d10+,0=d3d9 - glTexCoord2f(q.s0,q.t1); glVertex2f(q.x0,q.y0); - glTexCoord2f(q.s1,q.t1); glVertex2f(q.x1,q.y0); - glTexCoord2f(q.s1,q.t0); glVertex2f(q.x1,q.y1); - glTexCoord2f(q.s0,q.t0); glVertex2f(q.x0,q.y1); - } - ++text; - } - glEnd(); -} -#endif -// -// -////////////////////////////////////////////////////////////////////////////// -// -// Complete program (this compiles): get a single bitmap, print as ASCII art -// -#if 0 -#include -#define STB_TRUETYPE_IMPLEMENTATION // force following include to generate implementation -#include "stb_truetype.h" - -char ttf_buffer[1<<25]; - -int main(int argc, char **argv) -{ - stbtt_fontinfo font; - unsigned char *bitmap; - int w,h,i,j,c = (argc > 1 ? atoi(argv[1]) : 'a'), s = (argc > 2 ? atoi(argv[2]) : 20); - - fread(ttf_buffer, 1, 1<<25, fopen(argc > 3 ? argv[3] : "c:/windows/fonts/arialbd.ttf", "rb")); - - stbtt_InitFont(&font, ttf_buffer, stbtt_GetFontOffsetForIndex(ttf_buffer,0)); - bitmap = stbtt_GetCodepointBitmap(&font, 0,stbtt_ScaleForPixelHeight(&font, s), c, &w, &h, 0,0); - - for (j=0; j < h; ++j) { - for (i=0; i < w; ++i) - putchar(" .:ioVM@"[bitmap[j*w+i]>>5]); - putchar('\n'); - } - return 0; -} -#endif -// -// Output: -// -// .ii. -// @@@@@@. -// V@Mio@@o -// :i.

The engine uses a fixed time-step thread loop -* to simluate physics. A physics step contains the following phases: get collision information, -* apply dynamics, collision solving and position correction. It uses a very simple struct for physic -* bodies with a position vector to be used in any 3D rendering API. -* -* CONFIGURATION: -* -* #define PHYSAC_IMPLEMENTATION -* Generates the implementation of the library into the included file. -* If not defined, the library is in header only mode and can be included in other headers -* or source files without problems. But only ONE file should hold the implementation. -* -* #define PHYSAC_STATIC (defined by default) -* The generated implementation will stay private inside implementation file and all -* internal symbols and functions will only be visible inside that file. -* -* #define PHYSAC_NO_THREADS -* The generated implementation won't include pthread library and user must create a secondary thread to call PhysicsThread(). -* It is so important that the thread where PhysicsThread() is called must not have v-sync or any other CPU limitation. -* -* #define PHYSAC_STANDALONE -* Avoid raylib.h header inclusion in this file. Data types defined on raylib are defined -* internally in the library and input management and drawing functions must be provided by -* the user (check library implementation for further details). -* -* #define PHYSAC_DEBUG -* Traces log messages when creating and destroying physics bodies and detects errors in physics -* calculations and reference exceptions; it is useful for debug purposes -* -* #define PHYSAC_MALLOC() -* #define PHYSAC_FREE() -* You can define your own malloc/free implementation replacing stdlib.h malloc()/free() functions. -* Otherwise it will include stdlib.h and use the C standard library malloc()/free() function. -* -* -* NOTE 1: Physac requires multi-threading, when InitPhysics() a second thread is created to manage physics calculations. -* NOTE 2: Physac requires static C library linkage to avoid dependency on MinGW DLL (-static -lpthread) -* -* Use the following code to compile: -* gcc -o $(NAME_PART).exe $(FILE_NAME) -s -static -lraylib -lpthread -lopengl32 -lgdi32 -lwinmm -std=c99 -* -* VERY THANKS TO: -* Ramon Santamaria (github: @raysan5) -* -* -* LICENSE: zlib/libpng -* -* Copyright (c) 2016-2018 Victor Fisac (github: @victorfisac) -* -* This software is provided "as-is", without any express or implied warranty.
