  89 <p>
  90 Makes a connection to an RTSP server and read the data.
  91 rtspsrc strictly follows RFC 2326 and therefore does not (yet) support
  92 RealMedia/Quicktime/Microsoft extensions.
  93 </p>
  94 <p>
  95 RTSP supports transport over TCP or UDP in unicast or multicast mode. By
  96 default rtspsrc will negotiate a connection in the following order:
  97 UDP unicast/UDP multicast/TCP. The order cannot be changed but the allowed
  98 protocols can be controlled with the <a class="link" href="gst-plugins-good-plugins-rtspsrc.html#GstRTSPSrc--protocols" title='The "protocols" property'><span class="type">"protocols"</span></a> property.
  99 </p>
 100 <p>
 101 rtspsrc currently understands SDP as the format of the session description.
 102 For each stream listed in the SDP a new rtp_stream<code class="literal">d</code> pad will be created
 103 with caps derived from the SDP media description. This is a caps of mime type
 104 "application/x-rtp" that can be connected to any available RTP depayloader
 105 element.
 106 </p>
 107 <p>
 108 rtspsrc will internally instantiate an RTP session manager element
 109 that will handle the RTCP messages to and from the server, jitter removal,
 110 packet reordering along with providing a clock for the pipeline.
 111 This feature is implemented using the gstrtpbin element.
 112 </p>
 113 <p>
 114 rtspsrc acts like a live source and will therefore only generate data in the
 115 PLAYING state.
