## MDK: Multimedia Development Kit ### [Changelog](https://github.com/wang-bin/mdk-sdk/blob/master/Changelog.md) ### [API](https://github.com/wang-bin/mdk-sdk/wiki/Player-APIs) ### Features - [Simple and powerful API set](https://github.com/wang-bin/mdk-sdk/wiki/Player-APIs) - [Cross platform: Windows, UWP, Linux, macOS, Android, iOS, Raspberry Pi](https://github.com/wang-bin/mdk-sdk/wiki/System-Requirements) - [Hardware accelerated decoders](https://github.com/wang-bin/mdk-sdk/wiki/Decoders) - [0-copy GPU rendering for all platforms and all renderers(Vulkan is WIP.)](https://github.com/wang-bin/mdk-sdk/wiki/Zero-Copy-Renderer) - [Dynamic OpenGL](https://github.com/wang-bin/mdk-sdk/wiki/OpenGL-Support-Matrix) - [OpenGL, D3D11, Vulkan and Metal rendering w/ or w/o user provided context](https://github.com/wang-bin/mdk-sdk/wiki/Render-API) - Integrated with any platform native ui apps, gui toolkits or other apps via [OpenGL, D3D11, Vulkan and Metal](https://github.com/wang-bin/mdk-sdk/wiki/Render-API) ([OBS](https://github.com/wang-bin/obs-mdk), [Qt](https://github.com/wang-bin/mdk-examples/tree/master/Qt), [SDL](https://github.com/wang-bin/mdk-examples/tree/master/SDL), [GLFW](https://github.com/wang-bin/mdk-examples/tree/master/GLFW), [SFML](https://github.com/wang-bin/mdk-examples/tree/master/SFML) etc.) easily - [Seamless/Gapless media and bitrate switch for any media](https://github.com/wang-bin/mdk-sdk/wiki/Player-APIs) - HDR rendering in GPU - Optimized Continuous seeking. As fast as mpv, but much lower cpu, memory and gpu load. Suitable for timeline preview - [Smart FFmpeg runtime, dynamic load, compatible with 4.x/5.x abi](https://github.com/wang-bin/mdk-sdk/wiki/FFmpeg-Runtime) ## About SDK for Windows Desktop SDK is built by clang-cl 12.0 + lld with - [FFmpeg master](https://sourceforge.net/projects/avbuild/files/windows-desktop/ffmpeg-master-windows-desktop-clang-lite.tar.xz/download) - Windows SDK 10.0.19041.0 - MSVC CRT 14.28.29333 SDK can be used by any C or C++11 compiler, e.g. vs2015, vs2019, mingw g++, clang ### Use in Visual Studio #### Install via NuGet (Recommended) mdk is published on https://www.nuget.org/packages/mdk/. Now you can install it in visual studio. #### Import from Release Package mdk sdk can be imported by vs projects. Insert the following line in your vcxproj as the last element of `Project` (assume mdk-sdk is in the same dir as vcxproj) <Import Project="mdk-sdk\build\native\MDK.targets" Condition="Exists('mdk-sdk\build\native\MDK.targets')" /> Once installed or imported, necessary compile flags and link flags will be added, runtime dlls will be copied to output dir. ### Use in CMake Projects ``` include(mdk-sdk-dir/lib/cmake/FindMDK.cmake) target_link_libraries(your_target PRIVATE mdk) ``` ### [Runtime Requirements](https://github.com/wang-bin/mdk-sdk/wiki/System-Requirements#windows-desktop) - Vista+ - ucrt, vc140+ runtime Optional: - libEGL.dll, libGLESv2.dll, D3DCompiler_47/43.dll. Qt apps can use qt's dlls - vulkan ### [Supported Graphics APIs:](https://github.com/wang-bin/mdk-sdk/wiki/Render-API) - D3D11: recommended - [OpenGL(No UWP)](https://github.com/wang-bin/mdk-sdk/wiki/OpenGL-Support-Matrix): via WGL.
