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:

Setup AppRTC Node Server with our websocket server

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.
