Hi,

The sdp plugin doesn't seems to be able to handle the media proto of udp

gst-launch-1.0 rtsp://192.168.0.216/test
Progress: (open) Retrieving media info

otherwise be missing the right GStreamer RTSP extension plugin.
Additional debug info:

The sdp description is this:

Is there any other module I need to include for this or does the gstreamer
simply not support the udp proto ?

Thanks.
Ian.
