| <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.</p> |
