This page presents video examples on x86 platform using AppRTC.
Problems running the pipelines shown on this page? Please see our
GStreamer Debugging guide for help
.
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
Unidirectional Elements
Example
In this example we use rrwebrtcbin to send a video stream and rrwebrtcbin to receive the video stream.
Send Pipeline
The following pipeline will send a color bars h264 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
Receive Pipeline
The following pipeline will receive the video stream and display it:
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
You should be able to see a video pattern similar to Fig.1.
Bidirectional Element
Example
In this example we use two rrwebrtcbin elements, each sends a video stream and receives each other video stream.
Send-Receive Pipeline
The following pipeline 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 ! videoconvert ! \ x264enc key-int-max=2 ! rtph264pay ! web.video_sink \ web.video_src ! rtph264depay ! avdec_h264 ! videoconvert ! xvimagesink async=true
Send-Receive Pipeline
The following pipeline joins the call:
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
You should be able to see two windows with a video pattern similar to Fig.1.
VP8
Unidirectional Elements
Example
In this example we use rrwebrtcbin to send a video stream and rrwebrtcbin to receive the video stream.
Send Pipeline
The following pipeline will send a color bars vp8 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 ! vp8enc ! rtpvp8pay ! web.video_sink
Receive Pipeline
The following pipeline will receive the video stream and display it:
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
You should be able to see a video pattern similar to Fig.1.

In this example we use two rrwebrtcbin elements, each sends a video stream and receives each other video stream.
