ffmpeg stopped working with .m4a
This code (to extract a section) has worked well for a long time
ffmpeg -vcodec copy -ss 71 -t 624 /home/bill/Music/recordings/source.m4a /home/bill/Segment-01.m4a
But has now stopped working.
First I get "...source.m4a already exists - OK to delete"
ffmpeg -i aa.m4a -ss 00:00:00 -t 00:05:00 -acodec copy new.m4a
