I'll take a wild stab in the dark and suggest that it's an RTP stream  
containing H.264.  Can you watch the camera stream using "mplayer  
rtsp://<some-ip-address>/<some-name>" ?

I'll take your word for it, but personally I think that this will be a  
slower and less reliable test than just watching the stream for a few
