BigBlueButton HTML5 client test server

BigBlueButton is an open source web conferencing system for on-line learning. This is a public test server for the BigBlueButton HTML5 client currently under development.

Our goal for the upcoming release of the HTML5 client is to implement all the viewer capabilities of the Flash client. Students join online classes as a viewer. The HTML5 client will give remote students the ability to join from their Android and Apple (iOS 11+) devices. Users using the Flash and HTML5 clients can join the same meeting (hence the two choices above). We built the HTML5 client using web real-time communication (WebRTC), React, and MongoDB.

What can this developer build of the HTML5 client do right now? Pretty much everything the Flash client can do for viewers except (a) view a desktop sharing stream from the presenter and (b) send/receive webcam streams. We're working on (a) and (b). For now, we are really happy to share with you our progress and get your feedback on what has been implemeted so far. Enjoy!
