[FFmpeg-devel] [PATCH 0/6] 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.

We have partially support of demux PCM in mp4 with 1c42fd932. It's an
incorrect implementation by adding tag to movaudio_tags. This has been
fixed by patch 2/6 and 3/6.

Zhao Zhili (6):
  avformat/movenc: add PCM in mp4 support
  avformat/mov: fix ISO/IEC 23003-5 support
  avformat/isom_tags: remove ipcm from movaudio_tags
  avformat/mov: parse ISO-14496-12 ChannelLayout
  avformat/movenc: write ChannelLayout box for PCM
  fate/mov: add PCM in mp4 test
