Download Nightly Build SDK
Sourceforge
- Simple and powerful API set
- Cross platform: Windows, UWP, Linux, macOS, Android, iOS, tvOS, visionOS, Raspberry Pi
- Hardware accelerated decoders
- 0-copy GPU rendering for all platforms and all renderers(Vulkan is WIP.)
- Dynamic OpenGL
- OpenGL, D3D11, D3D12, Vulkan and Metal rendering w/ or w/o user provided context
- Integrated with any platform native ui apps, gui toolkits or other apps via OpenGL, D3D11/12, Vulkan and Metal (WinUI3, OBS, Flutter, Qt, SDL, GLFW, SFML, .NET Avalonia etc.) easily
- HDR display, HDR to SDR and SDR to HDR tone mapping. You can use HDR display in Qt6(6.6+ for macOS, 6.x for windows), OBS Studio and more.
- Seamless/Gapless media and bitrate switch for any media
- Optimized Continuous seeking. As fast as mpv, but much lower cpu, memory and gpu load. Suitable for timeline preview
- Subtitle rendering, including ass, plain text, bitmap, closed caption
- Smart FFmpeg runtime, dynamic load, compatible with 4.0~7.x abi
- Professional codecs: GPU accelerated HAP codec rendering, Blackmagic RAW, R3D

If fail to code sign: In Build Phase, add a New Run Script Phase with content

- mdk(libmdk.so.0/ibmdk.dylib/mdk.dll) and ffmpeg library(or standard ffmpeg libraries) are always REQUIRED
- libass.dll/libass.dylib/ass.framework/libass.so can be optional if not using subtitle rendering
- mdk-braw.dll/libmdk-braw.{so,dylib}: optional, for blackmagic raw videos
- mdk-r3d.dll/libmdk-r3d.{so,dylib}: optional, for RED raw videos
- mdk.pdb/libmdk.so*.dsym: debug symbols.
- Add libdav1d.dll/libdav1d.dylib/dav1d.framework/libdav1d.so from to support av1 software decoding

- sdk headers
- macOS, iOS:
player.setDecoders(MediaType::Video, {"VT", "hap", "FFmpeg", "dav1d"}); - Windows:
player.setDecoders(MediaType::Video, {"MFT:d3d=11", "D3D11", "CUDA", "hap", "FFmpeg", "dav1d"}); - Linux:
// XInitThreads(); // If using x11. before any x11 api call. some gui toolkits already call this, e.g. qt, glfw
SetGlobalOption("X11Display", DisplayPtr); // If using x11. Requred by VAAPI, VDPAU
player.setDecoders(MediaType::Video, {"VAAPI", "VDPAU", "CUDA", "hap", "FFmpeg", "dav1d"});- Raspberry Pi: use mdk-sdk-linux.tar.xz, delete libffmpeg.so.* to use system ffmpeg to support h264, hevc hardware decoder and 0-copy rendering
player.setDecoders(MediaType::Video, {"V4L2M2M", "FFmpeg:hwcontext=drm", "FFmpeg"});- Android:
SetGlobalOption("JavaVM", JvmPtr); // REQUIRED
player.setDecoders(MediaType::Video, {"AMediaCodec", "FFmpeg", "dav1d"});player.setProperty("avformat.fflags", "+nobuffer");
player.setProperty("avformat.fpsprobesize", "0");- License generator and validator
