The sdp_find_media_rtpmap() function searches the attribute list of the specified media structure, media, for the specified format. If the search is successful a pointer to that rtpmap attribute is returned. Otherwise it returns NULL. RETURN VALUES

Example 1 An (incomplete) SDP description that contains two media sections: audio and video. m=audio 49170 RTP/AVP 0 8 a=rtpmap:0 PCMU/8000 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. */ sdp_media_t *video; sdp_attr_t *mpv; video = sdp_find_media(session->s_media, "video); mpv = sdp_find_media_rtpmap(video, "32"); /* * Now the attribute structure sdp_attr_t, mpv will be having * values from the attribute field "a=rtpmap:32 MPV/90000" */ ATTRIBUTES
