Both PC's have a waveLAN interface and I transmit video images from one PC to the other over the wireless interface. I'm using vic v2.8 to transmit the video from a camera source. Here is my problem, which I hope I can get some advice on: I need to use rtpdump to see the rtcp packets coming in on the receiving end. I have not been able to do this yet and am wondering if I am using rtpdump correctly. Here is what I do... 1) start vic on machine A: vic IPaddr-of-B/23886 2) start vic on machine B: vic IPaddr-of-A/23886 3) start rtpdump on B: rtpdump -F rtcp -t 1 IPaddr-of-A/23886 > dump.txt "23886" is the port I'm using on both machines. The video transmission is one-way (from A to B) and I can successfully see the video on B's screen. However, the file "dump.txt" is always found empty when rtpdump finishes after 1 minute. Has anyone out there used rtpdump successfully? Faisal faisal@tamu.edu To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
