15 \fBsdp_attr_t *\fR\fBsdp_find_media_rtpmap\fR(\fBsdp_media_t *\fR\fImedia\fR,
16 \fBconst char *\fR\fIformat\fR);
22 The \fBsdp_find_media_rtpmap()\fR function searches the attribute list of the
23 specified media structure, \fImedia\fR, for the specified \fIformat\fR. If the
24 search is successful a pointer to that \fIrtpmap\fR attribute is returned.
25 Otherwise it returns \fINULL\fR.
29 The \fBsdp_find_media_rtpmap()\fR function returns the attribute (\fBsdp_attr_t
30 *\fR) on success and \fINULL\fR when the search fails or the mandatory input
31 parameters are \fINULL\fR.
34 \fBExample 1 \fRAn (incomplete) SDP description that contains two media
35 sections: audio and video.
39 m=audio 49170 RTP/AVP 0 8
42 m=video 51372 RTP/AVP 31 32
43 a=rtpmap:31 H261/90000
47 * Assuming that above description is parsed using sdp_parse() and that
48 * the parsed structure is in "session" sdp_session_t structure.
54 video = sdp_find_media(session->s_media, "video);
55 mpv = sdp_find_media_rtpmap(video, "32");
58 * Now the attribute structure sdp_attr_t, mpv will be having
59 * values from the attribute field "a=rtpmap:32 MPV/90000"
