Is it possible broadcast audio with screensharing with WebRTC

Question

is it possible broadcast audio with screensharing with WebRTC? Simple calling getUserMedia with audio: true fails by permission denied error. Is there

Answer 1

In Firefox, you can use getUserMedia to grab a screenshare/etc and mic audio in the same request, and can attach it to a PeerConnection. You can combine it with other streams -- multiple audio or video tracks in a single PeerConnection in Firefox requires Firefox 38 or later. Currently 38 is Developer Edition (formerly termed Aurora). 38 should go to release in around 9 weeks or so.
