QT基于MDK框架设计的视频播放器完整源码.zip

## MDK: Multimedia Development Kit ### Features - Simple and powerful API set - Cross platform: Windows, UWP, Linux, macOS, Android, iOS, Raspberry Pi - Hardware accelerated decoding and 0-copy GPU rendering for all supported platforms - OpenGL, D3D11, Vulkan and Metal rendering w/ or w/o user provided context - Integrated with any gui toolkit or app via OpenGL, D3D11, Vulkan and Metal (OBS, Qt, SDL, glfw, SFML and native ui etc.) easily - Seamless/Gapless media and bitrate switch for any media - Configurable FFmpeg runtime libraries. - HDR rendering in GPU - Optimized Continuous seeking. As fast as mpv, but much lower cpu, memory and gpu load. Suitable for timeline preview ## FFmpeg Runtime Lookup FFmpeg modules can be specified via environment var AVUTIL_LIB, AVCODEC_LIB, AVFORMAT_LIB, AVFILTER_LIB, SWRESAMPLE_LIB, SWSCALE_LIB, or SetGlobalOption() with key avutil_lib, avcodec_lib, avformat_lib, swresample_lib, swscale_lib, avfilter_lib. For example `SetGlobalOption("avutil_lib", "ffmpeg-4.dll")` If ffmpeg any module is not set, it's searched in the following order - current module dir > framework dir(apple) > system default search dir - single ffmpeg library > ffmpeg modules w/ version > ffmpeg modules w/o version ## About SDK for Windows Desktop SDK is built by clang-cl 12.0 + lld with - FFmpeg: https://sourceforge.net/projects/avbuild/files/windows-desktop/ffmpeg-master-windows-desktop-clang-static-lite.tar.xz/download - Windows SDK 10.0.19041.0 - MSVC CRT 14.26.28801 SDK can be used by any C or C++11 compiler, e.g. vs2015, vs2017, 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. ### Runtime Requirements - Vista+ - ucrt, vc140+ runtime Optional: - libEGL.dll, libGLESv2.dll, D3DCompiler_47/43.dll. Qt apps can use qt's dlls ### Supported Graphics APIs: - D3D11: recommended - OpenGL: via WGL. The default if EGL runtime is not found. - OpenGL ES2/3: via ANGLE or others. The default if EGL runtime is found. - Vulkan ### Supported Decoders: - FFmpeg. options: threads=N. e.g. -c:v FFmpeg. -c:v FFmpeg:threads=4 - MFT. options: d3d=0/9/11, pool=0/1. e.g. -c:v MFT(software), -c:v MFT:d3d=11(hardware). - CUDA - D3D11: via FFmpeg - DXVA: via FFmpeg - NVDEC: via FFmpeg - CUVID: via FFmpeg - QSV: via FFmpeg ### Examples gapless playback for any audio and video: mdkplay.exe(or glfwplay.exe/window.exe/sdlplay.exe) file file2 ...
