How to capture RTSP flow?

0

Hi!

I'm using Unreal Media Server and would like to capture the network traffic related to RTSP protocol. I'm able to get some data but it is not in the format I was expecting. I can't see OPTIONS in the info column and can't follow the RTSP negotiation.

Is there any specific setting in wireshark so it can show RSTP packets in the full form?

RTP is not automatically detected over UDP.

RTP is difficult to detect reliably.

There is a heuristic, but it's a weak heuristic, and not enabled by default. Turn on the "Try to decode RTP outside of conversations" preference for RTP to enable it.

Note that it looks for a version number of 2 in the first octet, and a known payload type in the second octet, rather than a dynamic payload type.

Same problem for RTCP.

Same solution for RTCP ("Try to decode RTCP outside of conversations" preference for RTCP); the heuristics are a bit stronger, but still not enabled by default.
