Changelog. API

Features

• Simple and powerful API set
• Cross platform: Windows, UWP, Linux, macOS, Android, iOS, Raspberry Pi
• Hardware accelerated decoders
• 0-copy GPU rendering for all platforms and all renderers(Vulkan is WIP.)
• Dynamic OpenGL
• OpenGL, D3D11, 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, Vulkan and Metal (OBS, Qt, SDL, GLFW, SFML etc.) easily
• Seamless/Gapless media and bitrate switch for any media
• 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
• Professional codecs: GPU accelerated HAP codec rendering, Blackmagic RAW

API Levels

• ABI level APIs(not public): the implementation, in abi namespace. depends on c++ abi. build and runtime abi must be matched. Used internally and for plugins.
• C APIs: No C++ ABI restriction.
• C++ APIs: a header only thin wrapper for C APIs. No C++ ABI restriction. No user code change to switch between ABI level APIs and C++ APIs.

Install

CMake

	include(mdk-sdk-dir/lib/cmake/FindMDK.cmake)
