checkScreenSharingCapability in Chrome 76 returns extensionRequired: "chrome"

The TokBox documentation is confusing because it clearly states:

Important: As of Chrome 72+ and Firefox 52+, an extension is no longer needed for screen sharing. The browser prompts the end user for access to the screen as it would for access to the camera.

However, the sample code has:

OT.checkScreenSharingCapability(function(response) {
  if(!response.supported || response.extensionRegistered === false) {
    // This browser does not support screen sharing
  }
});

And chrome version 76 returns:

extensionInstalled: false
extensionRegistered: false
extensionRequired: "chrome"
supported: true

So Chrome 76 will say it's unsupported. Firefox v68 returns extensionRegistered = undefined so it passes. If I ignore the error and try to do screensharing in Chrome anyway, it fails and says the extension is required.

Solution

  • Fixed by updating @opentok/client from 2.15.1 to 2.16.2
