This page presents some GstRrWebRTC audio examples using OpenWebRTC.

Opus

Unidirectional Elements

Example

In this example we use rrwebrtcsink to send an audio stream and rrwebrtcsrc to receive the audio stream.

Send pipeline

The following pipeline will send periodic ticks:

gst-launch-1.0  rrwebrtcsink 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 rrwebrtcsrc 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 rrwebrtcbin 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 rrwebrtcbin 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 rrwebrtcbin 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.
