This page presents some GstRrWebRTC audio examples on x86 platform using OpenWebRTC.
Opus
Unidirectional Elements
Example
In this example we use rrwebrtcbin to send an audio stream.
Send pipeline
The following pipeline will send periodic ticks:
gst-launch-1.0 rrwebrtcbin start-call=true signaler=GstOwrSignaler \
signaler::server_url=https://webrtc.ridgerun.com:8443 \
signaler::session_id=1234ridgerun name=web audiotestsrc is-live=true wave=8 ! audioconvert ! audioresample \
! queue ! opusenc ! rtpopuspay ! web.audio_sink
Receive pipeline
The following pipeline will receive the periodic ticks:
gst-launch-1.0 rrwebrtcbin start-call=false signaler=GstOwrSignaler \
signaler::server_url=https://webrtc.ridgerun.com:8443 \
signaler::session_id=1234ridgerun name=web web.audio_src ! 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=https://webrtc.ridgerun.com:8443 \
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=https://webrtc.ridgerun.com:8443 \
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.
