I'm trying to retrieve video file from a pcap file. I've intercepted the traffic from and to my ip camera. The objective of my project is to proove that the camera sent video/audio streaming and I need to be able to replay the video.

So far I did videosnarf to extract the video files from the pcap file. It extracted successfully, but it consisted of just few bytes. So I won't be able to replay it on any video player.

I tried to install openrtsp or live555, but there was a fatal error so I posted the error on the live55 mailing list.

I tried to find the rtp/rtsp payloads with wireshark, it didn't show anything.

On my wireshark I've received this info:

37 8.172498 RTP 50 Unknown RTP version 3

or this:

307 53.300484 ec2-52-70-134-186.compute-1.amazonaws... RTMP 1514 Video Data

What's an RTP version 3? Why is it unknown?

How can I retrieve video files from rtp/rtmp capture file? Is it possible?

Help, my presentation is in 4 hours from now.

Regards, monyet

PS: I found this thread but it didn't help me.
