This page presents some GstWebRTC audio examples using OpenWebRTC.

Opus

Unidirectional Elements

Example

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

Send pipeline

The following pipeline will send periodic ticks:

gst-launch-1.0  webrtcsink start-call=true signaler=GstOwrSignaler signaler::server_url=http://webrtc.ridgerun.com:8080 \
signaler::session_id=1234ridgerun name=web audiotestsrc is-live=true wave=8 ! audioconvert ! audioresample \
! queue ! opusenc ! rtpopuspay ! web.audio

Receive pipeline

The following pipeline will receive the periodic ticks:

gst-launch-1.0 webrtcsrc start-call=false signaler=GstOwrSignaler signaler::server_url=http://webrtc.ridgerun.com:8080 \
signaler::session_id=1234ridgerun name=web web.audio ! rtpopusdepay ! opusdec ! audioconvert ! \
alsasink async=false

When executing the two previous pipelines, you should be able to listen the ticks in the receiving computer.

Bidirectional Element

Example

In this example we use two webrtcbin elements, each sends an audio stream and receives each other audio stream.

Send-Receive Pipeline

The following pipeline will send a white noise audio stream and receive the ticks audio stream sent by the next pipeline. This pipeline starts the call.

gst-launch-1.0 webrtcbin start-call=true signaler=GstOwrSignaler signaler::server_url=http://webrtc.ridgerun.com:8080 \
signaler::session_id=1234ridgerun name=web audiotestsrc is-live=true wave=5 ! audioconvert ! \
audioresample ! queue ! opusenc ! rtpopuspay ! web.audio_sink web.audio_src ! rtpopusdepay ! \
opusdec ! audioconvert ! alsasink sync=false async=false

Send-Receive Pipeline

The following pipeline will send ticks audio stream and receive the white noise audio stream sent by the previous pipeline. This pipeline joins the call.

gst-launch-1.0 webrtcbin start-call=false signaler=GstOwrSignaler signaler::server_url=http://webrtc.ridgerun.com:8080 \
signaler::session_id=1234ridgerun name=web audiotestsrc is-live=true wave=8 ! audioconvert ! \
audioresample ! queue ! opusenc ! rtpopuspay ! web.audio_sink web.audio_src ! rtpopusdepay ! \
opusdec ! audioconvert ! alsasink sync=false async=false

When executing the two previous pipelines, you should be able to listen the ticks and the white noise.
