The Norwegian Unix User Group is +recording our montly presentation on video, and recently we have +worked on improving the quality of the recordings by mixing the slides +directly with the video stream. For this, we use the +dvswitch package from +the Debian video team. As this require quite one computer per video +source, and NUUG do not have enough laptops available, we need to +borrow laptops. And to avoid having to install extra software on +these borrwed laptops, I have wrapped up all the programs needed on a +bootable USB stick. The software required is dvswitch with assosiated +source, sink and mixer applications and +dvgrab. To allow this setup to +work without any configuration, I've patched dvswitch to use +avahi to connect the various parts +together. And to allow us to use laptops without firewire plugs, I +upgraded dvgrab to the one from Debian/unstable to get one that work +with USB sources. We have not yet tested this setup in a production +setup, but I hope it will work properly, and allow us to set up a +video mixer in a very short time frame. We will need it for +Go Open 2009.
+ +The +USB image is for a 1 GB memory stick, but can be used on any +larger stick as well.
