[FFmpeg-user] Copy Audio

Tue Dec 18 00:53:50 EET 2018

I too have the same problem.  In the previous version, I could trim mp4 
files with pcm audio, but not 4.1.   MP4 files with pcm audio are found 
in most high end cameras and as such should be supported, even though it 
may not be part of the official mp4 spec.
