       are NULL.

       Example	1 An (incomplete) SDP description that contains two media sec‐
       tions: 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	 *my_media;
	 my_media = sdp_find_media(session->s_media, "video");
