sdpdemux

sdpdemux currently understands SDP as the input format of the session description. For each stream listed in the SDP a new stream_%u 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.

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.

sdpdemux acts like a live element and will therefore only generate data in the PLAYING state.

Example launch line

 gst-launch-1.0 souphttpsrc location=http://some.server/session.sdp ! sdpdemux ! fakesink

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.
