  1. The sharing browser sends the video stream to the server with – publishStream.
  2. Another browser or device fetches this video stream by its name – playStream.
  3. As a result, the broadcasting browser sends a WebRTC stream that is broadcasted in several different formats depending on the receiving browser or mobile device.

 

Screensharing example in the Google Chrome browser

In this example we captured the screen using the Google Chrome browser in 1024×768 resolution at 10 fps and sent the video stream to the server. The sent video stream can be seen in the upper left corner.

Then, we connect to the server and play the same video stream right on the server. The same way you can connect from other browsers or locations and test how the stream is shared.

You can find the step by step description of this process in the Testing section.
