This page presents some audio examples of GstWebRTC using OpenWebRTC's signaler.
Opus
Unidirectional
Example: In this example we use webrtcsink to send an audio stream and webrtcsrc to receive the audio stream.
The following pipeline will send periodic ticks:
gst-launch-1.0 webrtcsink start-call=true 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
The following pipeline will receive the periodic ticks:
gst-launch-1.0 webrtcsrc start-call=false 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
Example: In this example we use two webrtcbin elements, each sends an audio stream and receives each other audio stream.
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::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
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::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.
