#9177 new defect

Opus end trimming isn't handled correctly for opus-in-mp4.

Reported by: Dale Curtis Owned by:
Priority: normal Component: avformat
Version: git-master Keywords: opus mov
Cc: Blocked By:
Blocking: Reproduced by developer: no
Analyzed by developer: no


Summary of the bug:
End trimming test cases for opus-in-mp4 using edit lists don't work properly. Converting either of the attached mp4 files to wave and playing back the result will correctly trim the pre-skip at the front, but doesn't remove the beep at the end.

AFAICT the edit list isn't being utilized correctly for these files.

How to reproduce:

% ffmpeg -i opus_fragmented.mp4 out.wav
% ffplay out.wav

ffplay version N-101553-g434b626b7a Copyright (c) 2003-2021 the FFmpeg developers
  built with gcc 9.3-win32 (GCC) 20200320

I also had a problem that opus does not play immediately in VLC, while it does in ffplay and mpv.
