a=rtpmap:8 PCMA/8000
m=video 51372 RTP/AVP 31 32
a=rtpmap:31 H261/90000
a=rtpmap:32 MPV/90000

/*
* Assuming that above description is parsed using sdp_parse() and that
* the parsed structure is in "session" sdp_session_t structure.
*/

my_media = sdp_find_media(session->s_media, "video");

/*
* my_media now points to the structure containg video media section
* information
*/
