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 takes audio from the microphone, encodes it to AC3 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. Additionally, it requires an anonymous user without a password.

MAPPING=/stream
IP_MIN=239.255.255.253
IP_MAX=239.255.255.255
