testing WebRTC Screen Sharing

Testing a screen sharing from a browser

Test sending a video stream with screen sharing using the Google Chrome browser

Use these instructions for quick installation and configuration of the server. In addition to that, you can connect to our demo server to perform the tests.

Test plan

  1. Connect to WCS server
  2. In the Google Chrome browser, share the screen and start publishing the video stream
  3. Check video stream playback in another browser


Screen sharing test

For clarity of this test, we additionally use the VLC media player application in which the video clip is played cyclically. In your testing, you can use other screen sharing options.

1. Log in to the web-interface of the server



2. Select “Screen Sharing” from the menu on the left side of the page



3. The line for entering the URL address of the stream by default shows the WSS address of your WCS server and a random stream name. Copy the stream name for further testing and click “Start”



4. After clicking on the “Share Screen” button, the browser asks what exactly needs to be shared – the entire screen, application or a specific browser tab. For this testing, we selected the “Application Window” and the application “VLC media player”. Make a selection and click the “Share” button.



5. The page displays a preview of the broadcast stream with a screen demonstration. Also under the line with the stream name the current status of the stream on the WCS server is displayed



6. Open another browser, log in to the web interface of the server, select “Player” from the menu on the left side of the page, enter the stream name that you copied on the “Screen Sharing” page in the “Stream” field and click the “Start” button 



7. Done! In the other browser, we received a video stream of a screen demonstration that was launched in the Google Chrome browser



8. To complete the publication of the stream with a screen demonstration, we will return to the Chrome browser and click the “Stop” button



Above, we tested the screen sharing experience in Google Chrome. Similarly, screen sharing using a WCS server works in other browsers and mobile applications for Android.
