Description

Makes a connection to an RTSP server and read the data. rtspsrc strictly follows RFC 2326 and therefore does not (yet) support RealMedia/Quicktime/Microsoft extensions.

RTSP supports transport over TCP or UDP in unicast or multicast mode. By default rtspsrc will negotiate a connection in the following order: UDP unicast/UDP multicast/TCP. The order cannot be changed but the allowed protocols can be controlled with the "protocols" property.

rtspsrc currently understands SDP as the format of the session description. For each stream listed in the SDP a new rtp_streamd 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.

rtspsrc 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. This feature is currently fully implemented with the gstrtpbin in the gst-plugins-bad module.

rtspsrc acts like a live source and will therefore only generate data in the PLAYING state.

Example launch line

gst-launch rtspsrc location=rtsp://some.server/url ! fakesink
Establish a connection to an RTSP server and send the raw RTP packets to a fakesink.
