 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.
