[Ffmpeg-user] Running in the background?

The problem is that ffmpeg tries to read from the terminal (for the "Press
[q] to stop encoding" feature). If it is in background, it gets a SIGTTIN
when it tries to read from the tty.

In the source code, I see the only possibility seems to be encoding from the
standard input. You should probably file a feature-request.

In the meantime, you should probably try using screen, which is very fine
for that.

I am sorry for you. ;-)
