 | The multicast clients can't be on the same machine as the server. Please use at least 2 machines (one as a server and one as a client). |
This wiki provides an example that combines a H264 video and an AAC audio stream into a single mapping and serves it to a multicast group.

GstRtspSink Pipeline
The following pipeline combines an H264 video and an AAC audio stream into a single mapping and serves it to a multicast group found between 239.255.255.253 and 239.255.255.255 and a port between 5000 and 6000.
