Michael Bradshaw b1699f4ac3 avformat/movenc: use enum values directly for colr atom 
The switch cases were missing:

  - Primaries: bt470m, film, smpte428, and ebu3213.
  - TRCs: gamma22, gamma28, linear, log, log_sqrt, iec61966_2_4, bt1361,
    iec61966_2_1, bt2020_10bit, and bt2020_12bit.
  - Space: rgb, fcc, ycgco, bt2020_cl, smpte2085, chroma-derived-nc,
    chroma-derived-c, and ictcp.

They also annoyingly remapped the following (which are functionally
equivalent but can be treated differently by clients):

  - smpte240m primaries to smpte170m.
  - smpte170m TRC to bt709.
  - bt470bg color space to smpte170m.

The enum values in FFmpeg are the same values as ITU-T H.273 and
ISO/IEC 23001-8 so we can just use them directly, which is both simpler
and preserves the user intent.

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 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.

Documentation

The offline documentation is available in the doc/ directory.

The online documentation is available in the main website and in the wiki.
