A ticket with the stack trace could definitely be useful. But as I
mentioned, a low-level ffmpeg library problem that results from a
noisy recording will be tough to fix.
If my suspicion is right and uninitialized data is involved, it should
show up when you manually run valgrind on mythcommflag:
valgrind --leak-check=no --track-origins=yes /path/to/mythcommflag options...
The valgrind output could also be useful in a ticket.
Uninitialized data is a good explanation (though not the only one)
when there are intermittent failures on the same input.
