<a name="gst-plugins-bad-plugins-sdpdemux.description"></a><h2>Description</h2>
<p>
sdpdemux currently understands SDP as the input format of the session description.
For each stream listed in the SDP a new stream_<code class="literal">u</code> pad will be created
with caps derived from the SDP media description. This is a caps of mime type
"application/x-rtp" that can be connected to any available RTP depayloader
element. 
</p>
<p>
sdpdemux will internally instantiate an RTP session manager element
that will handle the RTCP messages to and from the server, jitter removal,
packet reordering along with providing a clock for the pipeline. 
</p>
<p>
sdpdemux acts like a live element and will therefore only generate data in the 
PLAYING state.

 Establish a connection to an HTTP server that contains an SDP session description
that gets parsed by sdpdemux and send the raw RTP packets to a fakesink.
