Niklas Haas a526f0cc3a fftools/ffplay: fix YUV conversion mode 
GL and Metal cache the state at time of texture creation. GLES2 and
Direct3D 11 use the state at time of the render copy call.

So the only way we can get the correct behavior consistently is by
making sure the state is set for both the upload *and* the draw call.
This probably isn't our bug to fix (upstream should make itself behave
consistently and also document its functions), but as it stands,
`ffplay` is misrendering BT.709 as BT.601 on my stock Linux system, and
that leaves a bad taste in my mouth.

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.
