[FFmpeg-devel] [PATCH v3 0/5] add PCM in mp4 support

[Zhao Zhili]

From: Zhao Zhili <zhilizhao at tencent.com>

This patchset adds support of demux/mux PCM in mp4, and related channel
layout information. PCM in mp4 is defined by ISO/IEC 23003-5. The channel
layout tag 'chn' is defined by ISO/IEC 14496-12 with reference to ISO/IEC
23001-8.

v3:
1. Rebase on master
2. Reorder the patchset to add demux support first, then mux
3. Add pcmC and chnl support in a single patch to movenc

v2:
1/8: simplied with switch-case
2-3/8: cherry-picked from jeeb's work
4/8: use switch-case and add log message
5/8:
6/8: 
  a. check version and flags
  b. support number of channels >= 64 with custom layout
  c. fix some channel layout operations like assignment directly
  d. return error for unsupported channel configurations
  e. warning when skiping bytes
7/8: support number of channels >= 64
8/8: fix fate-mov-mp4-pcm-float dependency

Zhao Zhili (5):
  avformat/mov: fix ISO/IEC 23003-5 support
  avformat/isom_tags: remove ipcm from movaudio_tags
  avformat/mov: parse ISO-14496-12 ChannelLayout
