RTP bin combines the functions of gstrtpsession, gstrtpssrcdemux, gstrtpjitterbuffer
and gstrtpptdemux in one element. It allows for multiple RTP sessions that will
be synchronized together using RTCP SR packets.
</p>
<p>
gstrtpbin is configured with a number of request pads that define the
functionality that is activated, similar to the gstrtpsession element.
</p>
<p>
To use gstrtpbin as an RTP receiver, request a recv_rtp_sink_%<code class="literal">d</code> pad. The session
number must be specified in the pad name.
Data received on the recv_rtp_sink_%<code class="literal">d</code> pad will be processed in the gstrtpsession
manager and after being validated forwarded on gstrtpssrcdemuxer element. Each
RTP stream is demuxed based on the SSRC and send to a gstrtpjitterbuffer. After
the packets are released from the jitterbuffer, they will be forwarded to a
gstrtpptdemuxer element. The gstrtpptdemuxer element will demux the packets based
on the payload type and will create a unique pad recv_rtp_src_%<code class="literal">d_</code>%<code class="literal">d_</code>%<code class="literal">d</code> on
gstrtpbin with the session number, SSRC and payload type respectively as the pad
name.
</p>
<p>
To also use gstrtpbin as an RTCP receiver, request a recv_rtcp_sink_%<code class="literal">d</code> pad. The
session number must be specified in the pad name.
</p>
<p>
If you want the session manager to generate and send RTCP packets, request
the send_rtcp_src_%<code class="literal">d</code> pad with the session number in the pad name. Packet pushed
on this pad contain SR/RR RTCP reports that should be sent to all participants
in the session.
</p>
<p>
To use gstrtpbin as a sender, request a send_rtp_sink_%<code class="literal">d</code> pad, which will
automatically create a send_rtp_src_%<code class="literal">d</code> pad. If the session number is not provided,
the pad from the lowest available session will be returned. The session manager will modify the
SSRC in the RTP packets to its own SSRC and wil forward the packets on the
send_rtp_src_%<code class="literal">d</code> 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 GstRtpSession::request-pt-map signal when it needs such a
mapping. One can clear the cached values with the GstRtpSession::clear-pt-map
signal.
</p>
<h3>Example pipelines</h3>
<p>
</p>
<pre class="programlisting">
gst-launch udpsrc port=5000 caps="application/x-rtp, ..." ! .recv_rtp_sink_0 \
gstrtpbin ! rtptheoradepay ! theoradec ! xvimagesink
</pre>
<p>
Receive RTP data from port 5000 and send to the session 0 in gstrtpbin.
</p>
<p>
</p>
<pre class="programlisting">
gst-launch gstrtpbin name=rtpbin \
v4l2src ! ffmpegcolorspace ! ffenc_h263 ! rtph263ppay ! rtpbin.send_rtp_sink_0 \

rtpbin.send_rtcp_src_1 ! udpsink port=5003 sync=false async=false \
udpsrc port=5007 ! rtpbin.recv_rtcp_sink_1
</pre>
<p>
Encode and payload H263 video captured from a v4l2src. Encode and payload AMR
audio generated from audiotestsrc. The video is sent to session 0 in rtpbin
and the audio is sent to session 1. Video packets are sent on UDP port 5000
and audio packets on port 5002. The video RTCP packets for session 0 are sent
on port 5001 and the audio RTCP packets for session 0 are sent on port 5003.
RTCP packets for session 0 are received on port 5005 and RTCP for session 1
is received on port 5007. Since RTCP packets from the sender should be sent
as soon as possible and do not participate in preroll, sync=false and
async=false is configured on udpsink

Receive H263 on port 5000, send it through rtpbin in session 0, depayload,
decode and display the video.
Receive AMR on port 5002, send it through rtpbin in session 1, depayload,
decode and play the audio.
Receive server RTCP packets for session 0 on port 5001 and RTCP packets for
session 1 on port 5003. These packets will be used for session management and
synchronisation.
Send RTCP reports for session 0 on port 5005 and RTCP reports for session 1
on port 5007.
