主题: [FFmpeg-devel] [PATCH 2/2] avformat/mov: improve HEIF parsing
Parse iinf boxes and its child infe boxes to get the actual codec used
(AV1 for avif, HEVC for heic), and properly export extradata in a generic
way.
The avif tests reference files are updated as the extradata is now exported.

Hi James,
With the change, some errors occurred and the current FFmpeg failed to decode a
lot of videos that can be decoded by older FFmpeg.
[mov,mp4,m4a,3gp,3g2,mj2 @ 000001e6e79aac80] st: 0 edit list: 1 Missing key
frame while searching for timestamp: 1000
[mov,mp4,m4a,3gp,3g2,mj2 @ 000001e6e79aac80] st: 0 edit list 1 Cannot find an
index entry before timestamp: 1000.
[mov,mp4,m4a,3gp,3g2,mj2 @ 000001e6e79aac80] infe: version < 2 not supported
[mov,mp4,m4a,3gp,3g2,mj2 @ 000001e6e79aac80] error reading header
I'm not familiar with the mov. Is it possible to treat this error as a warning and
skip it when the version < 2?
Thanks,
Jianhua
