Gstreamer UDP Source Query

[Mohammad, Jamal M]

I found the udp src has timeout property which sends an message when there is no data received from the socket. This may help me to say that the stream is completed, but how to find out the start of stream. I am not using RTSP here right, only RTP

Only is you signal this information. An example, the RTSP protocol will announce the duration, so the other end will know because that duration have elapsed.

You could use a pad probe that watch for data, and implement a keep alive stile mechanism.
