Niklas Haas d312a33ed2 avfilter/drawutils: remove redundant xyz format check 
The code above this does a whitelist on desc->flags, which now includes
the (disallowed) AV_PIX_FMT_FLAG_XYZ for XYZ formats. So there is no
more need for a separate check, here.

  • 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.
