Subject: [FFmpeg-devel] [PATCH v2 0/8] add PCM in mp4 support
Date: Sat, 25 Feb 2023 02:28:41 +0800
Message-ID: <tencent_A713171C488B8E262090ADE6D4E7F1AAA006@qq.com> (raw)
From: Zhao Zhili <zhilizhao@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.
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
Jan Ekström (2):
avformat/mov: check that pcmC box is of the expected type
avformat/mov: base the endianness on just the LSB
Zhao Zhili (6):
avformat/movenc: add PCM in mp4 support
avformat/mov: fix ISO/IEC 23003-5 support
