Opus

Unidirectional elements

Example

In this example, we use rrwebrtcbin to send an audio stream and rrwebrtcbin to receive the audio stream.

Send Pipeline

PEER_CHANNEL=123peer
gst-launch-1.0 rrwebrtcbin rtcp-mux=true start-call=true signaler=GstPubnubSignaler \

Receive Pipeline

USER_CHANNEL=123peer
PEER_CHANNEL=123
gst-launch-1.0 rrwebrtcbin rtcp-mux=true start-call=false signaler=GstPubnubSignaler \

Bidirectional elements

Example

In this example we use two rrwebrtcbins, each send an audio stream and receives each other audio stream.
