If I am understanding you right, Matterhorn lets me use a Capture device that I build or buy, to capture the room/speaker? The file is then processed by Matterhorn and housed on the Matterhorn server so students can go into that room/lecture/series and watch? I am not seeing where the advantage is to just recording via a digital cam, making it a wmv or mp4 and throwing it on our file server as a link inside the Moodle classroom. Please tell me what I am missing.
As for BBB, seem can send its recordings to Matterhorn to be processed and put into the system. (from BBB wiki) OverviewMatterhorn is an open source lecture capture and video management system for education. When integrated with Matterhorn (see instructions below), BigBlueButton can record video, desktop, and audio and send the files to Matterhorn for processing and playback. >From a technical point of view, in the BigBlueButton API, when you pass the >parameter 'record=true' with create, BigBlueButton will create a session and >record the slides, chat, audio, desktop, and webcam for later processing. After the session finishes, the BigBlueButton server will run one (or more) ingest and processing scripts that will process the captured data into a format for playback. The instructions below show you how to install and configure the Matterhorn ingest and processing scripts. When called by BigBlueButton, these scripts will create two video files: one with webcam + audio, the other for desktop sharing, along with an XML file (called dublin core) and bundle everything into a single zip file. It will then scp the zip file to your Matterhorn server for processing. The Matterhorn ingest and processing will scale the resolution of the desktop video to 640x480 before sending to Matterhorn. >>> Christopher Brooks 05/18/12 4:07 PM >>> Hi Roger, > My confusion: > > If i integrate BBButton into Matterhorn then I can use BBB as a > capture device to get vids into matterhorn. > What's the advantage to having matterhorn over just using BBB to > capture and linking the vids inside of my moodle classroom? If you want to capture using a physical device in the classroom you can't do this with BBB. With a Matterhorn capture agent you can, so you don't have to be using BBB at all, and you can capture input from VGA devices. As far as the Matterhorn processing chain versus the BBB processing chain or the quality of the output videos I'm not sure; I don't know BBB well enough.
