Zhao Zhili be7ac511a6 avformat/mov: avss box should be AV_CODEC_ID_CAVS 
I cannot find the spec, but according to the original commit
d4fdba0df7, it's CAVS. e571305a71 changed it to AVS by
accident. Ten years on, nothing happened. We still have the
sample [1], however, since there is no cavs_mp4tofoobar bsf, the
cavs decoder doesn't work. I don't know if there is any use case.

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.
