Server Setup
To run the examples first enable the Websocket server:
$GOPATH/bin/collidermain -port=8089 -tls=false
Then, enable the AppRTC Node server in a different terminal window:
cd <PATH>/apprtc-node-server node ./bin/www
Note: Make sure you previously install dependencies needed for enable the servers, if you didn't, follow this link:

H264 + Opus
Unidirectional Elements
Example
In this example we use rrwebrtcbin to send a video stream and an audio stream, and we use rrwebrtcbin to receive the video and audio streams.
Send Pipeline
The following pipeline will send periodic ticks and a video stream:
gst-launch-1.0 rrwebrtcbin start-call=true signaler=GstApprtcSignaler signaler::server_url=http://localhost:8080 \ signaler::session_id=1234ridgerun name=web videotestsrc is-live=true ! videoconvert ! \ x264enc key-int-max=2 ! rtph264pay ! web.video_sink \ audiotestsrc is-live=true ! opusenc ! rtpopuspay ! web.audio_sink
Receive Pipeline
The following pipeline will receive the video stream and the ticks and do the playback:
gst-launch-1.0 rrwebrtcbin start-call=false signaler=GstApprtcSignaler signaler::server_url=http://localhost:8080 \ signaler::session_id=1234ridgerun name=web web.video_src ! rtph264depay ! avdec_h264 ! videoconvert ! \ xvimagesink async=true web.audio_src ! rtpopusdepay ! opusdec ! autoaudiosink
When executing the two previous pipelines, you should be able to listen the ticks in the receiving computer and see a video pattern similar to Fig.1.
Bidirectional Element
Example
In this example we use two rrwebrtcbins, each send a video stream and an audio stream, and receives each other video and audio streams.
Send-Receive Pipeline
The following pipeline starts a call, sends white noise audio stream and a color bar video stream, and receives audio and video streams.
gst-launch-1.0 rrwebrtcbin start-call=true signaler=GstApprtcSignaler signaler::server_url=http://localhost:8080 \ signaler::session_id=1234ridgerun name=web videotestsrc is-live=true ! videoconvert ! \ x264enc key-int-max=2 ! rtph264pay ! web.video_sink \ web.video_src ! rtph264depay ! avdec_h264 ! videoconvert ! xvimagesink async=true \ web.audio_src ! rtpopusdepay ! opusdec ! autoaudiosink \ audiotestsrc is-live=true ! opusenc ! rtpopuspay ! web.audio_sink
Send-Receive Pipeline
The following pipeline joins the call, sends ticks audio stream and a color bar video stream, and receives audio and video streams.
gst-launch-1.0 rrwebrtcbin start-call=false signaler=GstApprtcSignaler signaler::server_url=http://localhost:8080 \ signaler::session_id=1234ridgerun name=web videotestsrc is-live=true ! videoconvert ! \ x264enc key-int-max=2 ! rtph264pay ! web.video_sink \ web.video_src ! rtph264depay ! avdec_h264 ! videoconvert ! xvimagesink async=true \ web.audio_src ! rtpopusdepay ! opusdec ! autoaudiosink \ audiotestsrc is-live=true ! opusenc ! rtpopuspay ! web.audio_sink
When executing the two previous pipelines, you should be able to listen audio streams and see two windows with video patterns similar to Fig.1.
Vp8 + Opus
Unidirectional Elements
Example
In this example, we use rrwebrtcbin to send a video stream and an audio stream, and we use rrwebrtcbin to receive the video and audio streams.
Send Pipeline
The following pipeline generates a color bars video stream and a ticks audiostream and starts the call:
gst-launch-1.0 rrwebrtcbin start-call=true signaler=GstApprtcSignaler signaler::server_url=http://localhost:8080 \ signaler::session_id=1234ridgerun name=web videotestsrc is-live=true ! vp8enc ! rtpvp8pay ! web.video_sink \ audiotestsrc is-live=true ! opusenc ! rtpopuspay ! web.audio_sink
Receive Pipeline
The following pipeline receives the video stream and the audio stream.
gst-launch-1.0 rrwebrtcbin start-call=false signaler=GstApprtcSignaler signaler::server_url=http://localhost:8080 \ signaler::session_id=1234ridgerun name=web web.video_src ! rtpvp8depay ! vp8dec ! videoconvert ! xvimagesink async=true \ web.audio_src ! rtpopusdepay ! opusdec ! autoaudiosink
After executing the two previous pipelines you should be able to see a window with a pattern like Fig.1, and hear the ticks audio stream.
