Hi, 
If the stream is set up
with SIP H323(H.245) MEGACO/H.248 or RTSP and those packets are in the trace Wireshark
will be able to 
Determine the payload
type and UDP ports used and decode RTP and payload. 
Regards 
Anderes

Hi, 
That's currently not possible but if you do get
the setup info in the trace I think it would decode.

Hi
Anders, thank you very much. I have got it for H264. 
 
Another
problem,  for H263+, it's using the dynamic payload type too, but I do not
found it in Edit->prefrences->protocols. 
 
How to
decode the H263+ ?

Hi, 
H264 "decoding" (only minimal decoding is made), is only available
from WS 0.99.7 and 
bugfixes has gon in since the release.(development builds available)  
 
If you haven't got the setup information in your trace there is the option to
do 
Edit->prefrences->protocols->h264 and set the Payload type 125 in your case. You still
have to  
do decode as RTP every time you open the trace.  
 
Regards 
Anders

Subject: [Wireshark-users] How to decode H264 ?  
 
 
Hi all, I'm new to Wireshark, it's a great software. Currently I using it to
analyse the H264 RTP video stream.  
When I captured the H264 RTP video stream, and try to decodec it - use the
menu" Decodec As..." and choosed "RTP" to decode it,  
 
but it just show me: "PT=Unknown (125), SSRC=0xD2D9EB2, Seq=35012,
Time=4266020486, Mark ",  
 
So there have anybody can help me how to decodec it as H264 ? 
 
Thank you in advance.
