Fei Wang 201cb35061 lavu/hwcontext_qsv: add support for 12bit content on Linux 
P012, Y212 and XV36 are used for 12bit content in FFmpeg VAAPI, so
these formats should be used in FFmpeg QSV too, however the SDK only
declares support for P016, Y216 and Y416. So this commit fudged mappings
between AV_PIX_FMT_P012 and MFX_FOURCC_P016, AV_PIX_FMT_Y212 and
MFX_FOURCC_Y216, AV_PIX_FMT_XV36 and MFX_FOURCC_Y416.

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.

Documentation
