<a name="gst-plugins-good-plugins-rtpbin.description"></a><h2>Description</h2>
<p>
RTP bin combines the functions of <a class="link" href="gst-plugins-good-plugins-rtpsession.html#GstRtpSession"><span class="type">GstRtpSession</span></a>, <a class="link" href="gst-plugins-good-plugins-rtpssrcdemux.html#GstRtpSsrcDemux"><span class="type">GstRtpSsrcDemux</span></a>,
<a class="link" href="gst-plugins-good-plugins-rtpjitterbuffer.html#GstRtpJitterBuffer"><span class="type">GstRtpJitterBuffer</span></a> and <a class="link" href="gst-plugins-good-plugins-rtpptdemux.html#GstRtpPtDemux"><span class="type">GstRtpPtDemux</span></a> in one element. It allows for multiple
RTP sessions that will be synchronized together using RTCP SR packets.
</p>
<p>
<a class="link" href="gst-plugins-good-plugins-rtpbin.html#GstRtpBin"><span class="type">GstRtpBin</span></a> is configured with a number of request pads that define the
functionality that is activated, similar to the <a class="link" href="gst-plugins-good-plugins-rtpsession.html#GstRtpSession"><span class="type">GstRtpSession</span></a> element.
</p>
<p>
To use <a class="link" href="gst-plugins-good-plugins-rtpbin.html#GstRtpBin"><span class="type">GstRtpBin</span></a> as an RTP receiver, request a recv_rtp_sink_%u pad. The session
number must be specified in the pad name.
Data received on the recv_rtp_sink_%u pad will be processed in the <a class="link" href="gst-plugins-good-plugins-rtpsession.html#GstRtpSession"><span class="type">GstRtpSession</span></a>
manager and after being validated forwarded on <a class="link" href="gst-plugins-good-plugins-rtpssrcdemux.html#GstRtpSsrcDemux"><span class="type">GstRtpSsrcDemux</span></a> element. Each
RTP stream is demuxed based on the SSRC and send to a <a class="link" href="gst-plugins-good-plugins-rtpjitterbuffer.html#GstRtpJitterBuffer"><span class="type">GstRtpJitterBuffer</span></a>. After
the packets are released from the jitterbuffer, they will be forwarded to a
<a class="link" href="gst-plugins-good-plugins-rtpptdemux.html#GstRtpPtDemux"><span class="type">GstRtpPtDemux</span></a> element. The <a class="link" href="gst-plugins-good-plugins-rtpptdemux.html#GstRtpPtDemux"><span class="type">GstRtpPtDemux</span></a> element will demux the packets based
on the payload type and will create a unique pad recv_rtp_src_%u_%u_%u on
rtpbin with the session number, SSRC and payload type respectively as the pad
name.
</p>
<p>
To also use <a class="link" href="gst-plugins-good-plugins-rtpbin.html#GstRtpBin"><span class="type">GstRtpBin</span></a> as an RTCP receiver, request a recv_rtcp_sink_%u 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_%u 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 <a class="link" href="gst-plugins-good-plugins-rtpbin.html#GstRtpBin"><span class="type">GstRtpBin</span></a> as a sender, request a send_rtp_sink_%u pad, which will
automatically create a send_rtp_src_%u 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_%u 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>
<p>
Access to the internal statistics of rtpbin is provided with the
get-internal-session property. This action signal gives access to the
RTPSession object which further provides action signals to retrieve the
internal source and other sources.

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
