Derek Buitenhuis 238a8ae92f pixdesc: Only check against valid entries when iterating over lists of enums 
Some of these enums have gaps in between their values, since they correspond
to the values in various specs, instead of being an incrementing list.

Fixes segfaults when, for example, using the valid API call:

   av_color_primaries_from_name("jecdec-p22");

  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides a mean to alter decoded Audio and Video through chain of 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.
