Audio copy oddness

Reported by: Atarikid Owned by:
Priority: important Component: avformat
Version: git-master Keywords: mov regression

Description

With some source files when you copy the audio stream, the result starts to loop the audio.
I have added such source file that triggers the problem.

ffmpeg/ -i Audiocopybug.mov -c:a copy -c:v copy -y destination.mp4

When playing the destination.mp4 file, you will notice the BigSur words get repeated. This is a small example file but with the larger files it really starting to sound ugly (everything is delayed 2 to multiple times). Very odd.
