GstRtspSink - Multicast+Authentication
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 to send an AC3 audio stream to a multicast group and make use of basic authentication.

GstRtspSink Pipeline
The following pipelines take audio from the microphone, encodes it to AC3, and serve it to a multicast group found between 239.255.255.253 and 239.255.255.255 and a port between 5000 and 6000. Additionally, it requires an anonymous user without a password.
