Please make sure that if stdin is not being used as an input, then the 
press [q] stuff still tries to use stdin. Note that the current behavior 
is that if stdin is connected to /dev/null, then the 'press [q]' logic 
is effectively disabled. This is by design. It is also used by ffserver 
when it fires up ffmpeg to do encoding.
