<a name="gst-plugins-good-plugins-gstrtpptdemux.description"></a><h2>Description</h2>
<p>
gstrtpptdemux acts as a demuxer for RTP packets based on the payload type of
the packets. Its main purpose is to allow an application to easily receive
and decode an RTP stream with multiple payload types.
</p>
<p>
For each payload type that is detected, a new pad will be created and the
<a class="link" href="gst-plugins-good-plugins-gstrtpptdemux.html#GstRtpPtDemux-new-payload-type" title='The "new-payload-type" signal'><span class="type">"new-payload-type"</span></a> signal will be emitted. When the payload for
the RTP stream changes, the <a class="link" href="gst-plugins-good-plugins-gstrtpptdemux.html#GstRtpPtDemux-payload-type-change" title='The "payload-type-change" signal'><span class="type">"payload-type-change"</span></a> signal will be
emitted.
</p>
<p>
The element will try to set complete and unique application/x-rtp caps on the
outgoing buffers and pads based on the result of the
<a class="link" href="gst-plugins-good-plugins-gstrtpptdemux.html#GstRtpPtDemux-request-pt-map" title='The "request-pt-map" signal'><span class="type">"request-pt-map"</span></a> signal.
