Live stream a session via RTMP

BigBlueButton implements the core conferencing capabilities you would expect in a commercial web conferencing system (and gives them to you under an open source license). The focus of the project is engagement with users. It does this by extending these core capabilities to give the presenter: multi-user whiteboard, shared notes, polling, breakout rooms. This works well for small to medium-sized sessions, and we currently recommend using BigBlueButton for sessions of 100 users or less. There are times, however, when you want to broadcast a session to much larger numbers of users. One way of achieving this would be to join a BigBlueButton session with a headless browser, capture the video and audio, and stream it to a CDN using RTMP. If we give the instructor the ability to initiate such a broadcast and provide the CDN endpoint, then the presenter could still have engagement with the users that join via the BigBlueButton client, but also reach the users that are watching live on the CDN stream.
