Re: [Playerstage-developers] Using CMVision with Camera1394

You're running in PUSH data mode, which means the read call will wait 
for a message to arrive, then return immediately, reading only that one 
message. You will need to keep reading until a bumper message makes it 
to the top of the queue to get bumper data. For a program like this, I 
would recommend you use PULL mode. See here for details:
