| <p>The RTP session manager models participants with unique SSRC in an RTP |
| session. This session can be used to send and receive RTP and RTCP packets. |
| Based on what REQUEST pads are requested from the session manager, specific |
| functionality can be activated.</p> |
| <p>The session manager currently implements RFC 3550 including:</p> |
| <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "> |
| <li class="listitem"><p>RTP packet validation based on consecutive sequence numbers.</p></li> |
| <li class="listitem"><p>Maintainance of the SSRC participant database.</p></li> |
| <li class="listitem"><p>Keeping per participant statistics based on received RTCP packets.</p></li> |
| <li class="listitem"><p>Scheduling of RR/SR RTCP packets.</p></li> |
| <li class="listitem"><p>Support for multiple sender SSRC.</p></li> |
| </ul></div> |
| <p>The rtpsession will not demux packets based on SSRC or payload type, nor will |
| it correct for packet reordering and jitter. Use <span class="type">GstRtpsSrcDemux</span>, |
| <a class="link" href="gst-plugins-good-plugins-rtpptdemux.html#GstRtpPtDemux"><span class="type">GstRtpPtDemux</span></a> and GstRtpJitterBuffer in addition to <a class="link" href="gst-plugins-good-plugins-rtpsession.html#GstRtpSession"><span class="type">GstRtpSession</span></a> to |
| perform these tasks. It is usually a good idea to use <a class="link" href="gst-plugins-good-plugins-rtpbin.html#GstRtpBin"><span class="type">GstRtpBin</span></a>, which |
| combines all these features in one element.</p> |
| <p>To use <a class="link" href="gst-plugins-good-plugins-rtpsession.html#GstRtpSession"><span class="type">GstRtpSession</span></a> as an RTP receiver, request a recv_rtp_sink pad, which will |
| automatically create recv_rtp_src pad. Data received on the recv_rtp_sink pad |
| will be processed in the session and after being validated forwarded on the |
| recv_rtp_src pad.</p> |
| <p>To also use <a class="link" href="gst-plugins-good-plugins-rtpsession.html#GstRtpSession"><span class="type">GstRtpSession</span></a> as an RTCP receiver, request a recv_rtcp_sink pad, |
| which will automatically create a sync_src pad. Packets received on the RTCP |
| pad will be used by the session manager to update the stats and database of |
| the other participants. SR packets will be forwarded on the sync_src pad |
| so that they can be used to perform inter-stream synchronisation when needed.</p> |
| <p>If you want the session manager to generate and send RTCP packets, request |
| the send_rtcp_src pad. Packet pushed on this pad contain SR/RR RTCP reports |
| that should be sent to all participants in the session.</p> |
| <p>To use <a class="link" href="gst-plugins-good-plugins-rtpsession.html#GstRtpSession"><span class="type">GstRtpSession</span></a> as a sender, request a send_rtp_sink pad, which will |
| automatically create a send_rtp_src pad. The session manager will |
| forward the packets on the send_rtp_src pad after updating its internal state.</p> |
| <p>The session manager needs the clock-rate of the payload types it is handling |
| and will signal the <a class="link" href="gst-plugins-good-plugins-rtpsession.html#GstRtpSession-request-pt-map" title="The “request-pt-map” signal"><span class="type">“request-pt-map”</span></a> signal when it needs such a |
| mapping. One can clear the cached values with the <a class="link" href="gst-plugins-good-plugins-rtpsession.html#GstRtpSession-clear-pt-map" title="The “clear-pt-map” signal"><span class="type">“clear-pt-map”</span></a> |
