https://github.com/webrtcHacks/adapter From MDN: https://developer.mozilla.org/en-US/docs/Web/API/Screen_Capture_API/Using_Screen_Capture Note: It may be useful to note that recent versions of the WebRTC adapter.js shim include implementations of getDisplayMedia() to enable screen sharing on browsers that support it but do not implement the current standard API. This works with at least Chrome, Edge, and Firefox.
