'Detecting if another tab is sharing screen on client's browser, and stopping them from sharing
Generally, with a webcam, if a browser tab, or a desktop app is using the webcam, other sources cannot use that webcam until the first app stops.
In a similar way is it possible to detect if there is a screen already being shared in another tab while my web app also tries to share a screen?
If so, is there a way to terminate that other stream before starting mine?
