Description

rtpssrcdemux acts as a demuxer for RTP packets based on the SSRC of the packets. Its main purpose is to allow an application to easily receive and decode an RTP stream with multiple SSRCs.

For each SSRC that is detected, a new pad will be created and the “new-ssrc-pad” signal will be emitted.

Example pipelines

1
gst-launch-1.0 udpsrc caps="application/x-rtp" ! rtpssrcdemux ! fakesink
Takes an RTP stream and send the RTP packets with the first detected SSRC to fakesink, discarding the other SSRCs.
