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.
