From: Zhao Zhili <zhiliz...@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.
