Sourceforge Github Releases NuGet

Features

Simple and powerful API set
Cross platform: Windows(x86, arm), 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.
Dolby Vision rendering, including Profile 5. Support HEVC and AV1.
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, binary compatible with 4.0~7.x
Professional codecs: GPU accelerated HAP codec rendering, Blackmagic RAW, R3D, nvJPEG2000

Install

CMake

  include(${MDK_SDK_DIR}/lib/cmake/FindMDK.cmake)
  target_link_libraries(your_target PRIVATE mdk)

Qt qmake

include($$MDK_SDK_DIR/mdk.pri)

CocoaPods

(Objective-)C/C++ Users

pod 'mdk'

Optionally you can use mdk.xcframework directly.

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

[ -n "$CODE_SIGN_IDENTITY" ] && find "$BUILT_PRODUCTS_DIR" -depth -name "lib*.dylib" -exec codesign -f -vvvv -s"${EXPANDED_CODE_SIGN_IDENTITY}" ${OTHER_CODE_SIGN_FLAGS:-} --preserve-metadata=identifier,entitlements,flags {} \;

Swift Users

pod 'swift-mdk'

and add

import swift_mdk

Nuget

Install via NuGet in Visual Studio for both Windows desktop and UWP

Distribute

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

Recommended settings

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"});
