  34 <p>The <a href="http://www.nuug.no/">Norwegian Unix User Group</a> is
  35 recording our montly presentation on video, and recently we have
  36 worked on improving the quality of the recordings by mixing the slides
  37 directly with the video stream.  For this, we use the
  38 <a href="http://dvswitch.alioth.debian.org/">dvswitch</a> package from
  39 the Debian video team.  As this require quite one computer per video
  40 source, and NUUG do not have enough laptops available, we need to
  41 borrow laptops.  And to avoid having to install extra software on
  42 these borrwed laptops, I have wrapped up all the programs needed on a
  43 bootable USB stick.  The software required is dvswitch with assosiated
  44 source, sink and mixer applications and
  45 <a href="http://www.kinodv.org/">dvgrab</a>.  To allow this setup to
  46 work without any configuration, I've patched dvswitch to use
  47 <a href="http://www.avahi.org/">avahi</a> to connect the various parts
  48 together.  And to allow us to use laptops without firewire plugs, I
  49 upgraded dvgrab to the one from Debian/unstable to get one that work
  50 with USB sources.  We have not yet tested this setup in a production
  51 setup, but I hope it will work properly, and allow us to set up a
  52 video mixer in a very short time frame.  We will need it for
  53 <a href="http://www.goopen.no/">Go Open 2009</a>.</p>

  55 <p><a href="http://www.nuug.no/pub/video/bin/usbstick-dvswitch.img.gz">The
  56 USB image</a> is for a 1 GB memory stick, but can be used on any
  57 larger stick as well.</p>
