RTP and SDP

[Mailing List SVR <lists () svrinformatica it>]

Hi all,

I have an rtp stream from a verint encoder and the manufacter refuse to give 
the sdp, using wireshark I discovered that the rtp payload type is 121 but yet 
vlc or any other player are unable to correct decode the video, I think I need 
an sdp like this to see the video:

v=0
o=- 3467013654633 3467013654634 IN IP4 192.168.2.23
s=verint
e=NONE
c=IN IP4 192.168.2.103
b=RR:0
t=0
m=video 2546 RTP/AVP 121
a=rtpmap:121 MP4V-ES/90000
a=fmtp:121 profile-level-id=3;config=????????

I need to find the config parameter to instruct the player about the decoding 
parameters, is possible to find this parameter using wireshark?

Can you give me some hints? 

thanks
Nicola
