Thank you for reporting a problem with a package in debian. I do not
have access to arm hardware, so I would need help from your side to
reproduce the issue.

However just by looking at your commandline:

# ffmpeg -r 30 -s cif -f video4linux2 -i /dev/video0 http://localhost:8090/feed.ffm

It looks like you are trying to grab from /dev/video0 and write to an
http stream? Please elaborate what you are trying to do, it currently
looks like an usage error to me.

On that basis, I've adjusted the bug severity.

If you can, please try to compile a newer upstream version, like the
version currently found in debian/unstable. That would make reproducing
the issue for me much easier.
