details the evaluation of several popular types of H. 264 decoder, including JM decoder, t264 decoder, x264 decoder, FFMPEG libavcodec, and Intel's IPP library. After evaluation, the author found that the fastest speed is Intel IPP, but intelIPP is a commercial software, and all other decoders belong to open-source projects. Therefore, the most suitable option is the FFMPEG with the second decoding speed,
Compiling X264 requires at least VS2013 Update 2 or later. This article uses VS2015.Example Project: Https://github.com/gitgjogh/FFmpeg-gitgjogh/tree/msvc/build_msvcBuild libav*** Using MSVC Compiler under Mingw32importvcvarInto MSYS (MINGW32)
