Marton Balint b81ed729ec avformat/mov_chan: rework ff_mov_read_chnl 
A lot of changes and fixes to channel layout parsing, notably
- get rid of dynamic allocation of channel positions
- signal unimplemented speaker positions as unknown instead of failure, but
  warn the user about it
- native order, and that a single channel only appears once was always assumed
  for less than 64 channels, obviously this was incorrect

  • 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.
