nohup is a stupid hack that does not really work. You should use setsid to
really detach the process from the controlling tty.

You need to prevent ffmpeg from reading on its standard input. For that,
either add "< /dev/null" or use the new -nostdin option.

Maybe you do not want the log file, but if it does not work, you need it. If
The advice above do not fix that problem, be sure to read the errors in the
log. You can consider discarding the log once you are sure everything works
fine (but even so, I do not advise to).
