<a name="gst-plugins-good-plugins-rtpsession.description"></a><h2>Description</h2>
<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>
signal.</p>

</pre></div> Receive theora RTP packets from port 5000 and send them to the depayloader,
decoder and display. Note that the application/x-rtp caps on udpsrc should be
configured based on some negotiation process such as RTSP for this pipeline
to work correctly.
<div class="informalexample"><pre class="programlisting">
gst-launch-1.0 udpsrc port=5000 caps="application/x-rtp, ..." ! .recv_rtp_sink rtpsession name=session \
.recv_rtp_src ! rtptheoradepay ! theoradec ! xvimagesink \
udpsrc port=5001 caps="application/x-rtcp" ! session.recv_rtcp_sink
</pre></div> Receive theora RTP packets from port 5000 and send them to the depayloader,
decoder and display. Receive RTCP packets from port 5001 and process them in
the session manager.
Note that the application/x-rtp caps on udpsrc should be

<div class="informalexample"><pre class="programlisting">

<div class="informalexample"><pre class="programlisting">

</pre></div> Send theora RTP packets through the session manager and out on UDP port
5000. Send RTCP packets on port 5001. Note that this pipeline will not preroll
correctly because the second udpsink will not preroll correctly (no RTCP
packets are sent in the PAUSED state). Applications should manually set and
keep (see <a href="/usr/share/gtk-doc/html/gstreamer-1.0/GstElement.html#gst-element-set-locked-state"><code class="function">gst_element_set_locked_state()</code></a>) the RTCP udpsink to the PLAYING state.
