This page presents some GstWebRTC audio examples using PubNub.

Opus

Unidirectional elements

Example

In this example we use webrtcsink to send an audio stream and webrtcsrc to receive the audio stream.

Send Pipeline

USER_CHANNEL=123
PEER_CHANNEL=123peer
gst-launch-1.0 webrtcsink rtcp-mux=true start-call=true signaler::user-channel=$USER_CHANNEL signaler::peer-channel=$PEER_CHANNEL name=web \
audiotestsrc is-live=true ! opusenc ! rtpopuspay ! web.audio

Receive Pipeline

USER_CHANNEL=123peer
PEER_CHANNEL=123
gst-launch-1.0 webrtcsrc rtcp-mux=true start-call=false signaler::user-channel=$USER_CHANNEL signaler::peer-channel=$PEER_CHANNEL name=web \
web.audio ! rtpopusdepay ! opusdec ! autoaudiosink

Bidirectional elements

Example

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

Send-Receive Pipeline

USER_CHANNEL=123
PEER_CHANNEL=123peer
gst-launch-1.0 webrtcbin rtcp-mux=true start-call=true signaler::user-channel=$USER_CHANNEL signaler::peer-channel=$PEER_CHANNEL name=web \
audiotestsrc is-live=true ! opusenc ! rtpopuspay ! web.audio_sink \
web.audio_src ! rtpopusdepay ! opusdec ! autoaudiosink

Send-Receive Pipeline

USER_CHANNEL=123peer
PEER_CHANNEL=123
gst-launch-1.0 webrtcbin rtcp-mux=true start-call=false signaler::user-channel=$USER_CHANNEL signaler::peer-channel=$PEER_CHANNEL name=web \
audiotestsrc is-live=true ! opusenc ! rtpopuspay ! web.audio_sink \
web.audio_src ! rtpopusdepay ! opusdec ! autoaudiosink
