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.

Today I upgraded to ffmpeg v 4.1. The following code used to work but no
longer does. What is the fix?
Please post the full command line you used along with the full uncut
terminal output. The answer will most likely be in there.
Best,
Kieran.
