Video of features coming in BigBlueButton 0.81

We’ve uploaded a short video highlighting the new capabilities in the upcoming BigBlueButton 0.81 (this will be our eleventh release).  This video was done using a development build of 0.81.

 This video details our efforts to advance the usability, features, and modularity of BigBlueButton for our community.

Specifically, the video shows for users

  • unified users and listeners
  • text tool for whiteboard
  • layout manager
  • record and playback of webcams and whiteboard

and for developers

  • JavaScript interface
  • changing the client settings on a per-user basis
We’re looking forward to releasing a beta of BigBlueButton 0.81 soon.

9:00 AM – 9:45 AM – BigBlueButton Project Update

Fred Dixon, BigBlueButton Project Manager, will give an update on the achievements this year, our progress towards the release of BigBlueButton 0.81 (our eleventh release), the upcoming work to support HTML5 and WebRTC, and an overview of the road map for 2013.

9:45 AM – 10:30 AM – Improving BigBlueButton’s User Interface

Tyler Copeland, independent designer, who has been responsible for evolving and improving BigBlueButton’s interface since the project’s beginning. In this presentation, Tyler will give an overview of the user interface evolution, the design challenges faced during the evolution, and a closer look at the ongoing work to design an HTML5-based interface for BigBlueButton.

(15 minute break)

10:45 – 11:30 – Evolving BigBlueButtons Architecture to Support HTML5

Richard Alam, Chief Architect for BigBlueButton, will describe the plans to modify and enhance the current BigBlueButton architecture to provided a unified support for a HTML5-based client and Flash-based client.

11:30 – 1:00 PM Break for Lunch

1:00 – 1:45 PM – Building upon BigBlueButton: The Mconf Project

Felipe Cecagno, BigBlueButton committer, and Leonardo Daronco, Mconf Developer, will describe how the Mconf team adapted and enhanced a fork of BigBlueButton (called Mconf Live) at the Federal University of Rio Grande do Sul (UFRGS), in Porto Alegre, Brazil. This presentation will also include their efforts to build a mobile version of BigBlueButton (Mconf Mobile), a Web Portal (Mconf Web), and a global network of BigBlueButton servers.

2:00 – 2:45 PM — Improving BigBlueButton’s Accessibility
Chad Pilkey and Justin Robinson, two developers at the Center for Development of Open Source Technologies, Seneca College, will present their efforts to improve BigBlueButton’s accessibility for students who are hearing or visually impaired, as well as prototype the addition of a polling module for BigBlueButton.

3:00 PM — 4:00 PM — General Feedback
In this wrap-up session, we invite anyone interested in the project to give us their feedback and suggestions for improving BigBlueButton for their use.

Docebo integrates BigBlueButton

Docebo, the company behind the Docebo Learning Management System, announced yesterday that they now offer integrated web conferencing using BigBlueButton.   According to their web site, over 12,000 organizations now use the Docebo LMS.

You can see their blog post announcing the integration.  The blog post links to their integration manual (pdf) showing how BigBlueButton works within their system.  Here’s a screen shot from the manual.

It’s great to see another LMS vendor offering integration support for BigBlueButton!

Kansas City Gig Fest

Over the weekend of March 22-24th, three members from the BigBlueButton team (Chad Pilkey, Fred Dixon, Calvin Walton) journeyed to Kansas City, MO, to participate in the Kansas City Gig Fest.

Our goal was to figure out how to hack WebRTC into BigBlueButton.

We took two approaches.  The first hack was to modify the HTML5 client so that the WebRTC video/audio appeared within a fixed region of the HTML5 client.  As WebRTC creates P2P connections with other browsers, there was transmission of audio/video to the BigBlueButton server.  While good for small group collaboration, the downside of this approach is there are no recordings of the sessions.

For the second hack we used the WebRTC2SIP gateway to transmit voice from WebRTC to FreeSWITCH.  However, as FreeSWITCH does not (yet) support the encrypted data from WebRTC, we used Asterisk 11 and an intermediary server. The diagram below shows an overview of the hack.

These were true hacks.   We actually had to work on these two hacks weeks in advance of the event to get everything ready for the final sprint.  

We were able to demo two users using latest Chrome browser to join a BigBlueButton session using the BigBlueButton Flash client.  However, instead of using the built-in audio in Flash (which is TCP/IP), the users clicked a ‘Join’ button in Javascript that triggered the WebRTC call that eventually reached FreeSWITCH.

The result was what you would expect: lower latency audio (WebRTC uses UDP).  The WebRTC support for audio will enable us to start prototyping the HTML5 client: Phase II.

Just to calibrate expectations: none of these hacks are planned for inclusion in 0.81.  There is enough on our plate to finish 0.81 for now, but we’re pushing hard in parallel to make progress on the WebRTC + HTML5 client for BigBlueButton.

Thank to Google, Mozilla, and Kansas City for putting on a first-rate hackathon.
