We're using BigBlueButton and opencast here, so looking forward to this
integration.
We'll try to make so time to test this integration.

The BigBlueButton project announces integration of BigBlueButton with
Matterhorn (1.1 and 1.2), providing an software-based lecture capture
solution for Matterhorn.
Background:
BigBlueButton is an open source web conferencing system for distance
education. It can broadcast the presenter's desktop, webcam, slides,
chat, and audio. The goal of the project is to provide remote
students a high-quality learning experience.
On September 12th we recently released BigBlueButton 0.8-beta with
integrated record and playback. As part of the development of
BigBlueButton 0.8, with the support of Boise State, Adam Hochman, and
others from the Matterhorn team, we added integration with Matterhorn
1.1 and 1.2, enabling the BigBlueButton server to package a recorded
lecture into a format that is readable by Matterhorn for ingest and
processing.
What is required to run BigBlueButton client?
The BigButtonButton client runs in Flash and works on Mac, Unix,
and PC web browsers. To capture the desktop requires the presenter's
browser to also run a Java applet.
How does BigBlueButton capture the lecture?
The BigBlueButton server receives the presenter's desktop,
webcam, and audio and, in turn, broadcasts them to other students.
As the server is broadcasting media, it's also recording it. The
recorded media comprises two video files (FLV), one for the webcam
and one for the desktop, and an audio file (WAV) for the voice
conference.
How does the BigBlueButton server package the captured lecture for
Matterhorn?
After the lecture finishes (everyone leaves the session), scripts
within the BigBlueButton server process the captured audio file,
video file, and desktop file into two FLV files: (1) webcam + audio,
(2) deskshare. The scripts also extract the meta data from the
presentation to create the Dublin Core.
How does the BigBlueButton server transmit the captured lecture to
Matterhorn?
Using public/private keys, the BigBlueButton server automatically
sends the packaged lecture to Matterhorn in the
/opt/matterhorn/felix/inbox/ just inbox directory directory. From
there, the regular Matterhorn ingest and processing process takes
over.
We invite anyone who is using Matterhorn 1.1 or 1.2 to try using
BigBlueButton for lecture capture and give us feedback. We're in our
beta testing for BigBlueButton 0.8 and we would like to get feedback
from some sites using BigBlueButton with Matterhorn before the final
release of BigBlueButton 0.8.
To setup a BigBlueButton 0.8-beta server, see

If you need help with the setup and integration of BigBlueButton or
with integration with Matterhron, please feel free to contact me
directly or post a follow-up message to this list.

P.S. I want again thank Brian Bolt (Boise State) and Adam Hochman
for their support in making this integration possible.
