  24       <div class="date">28th December 2008</div>
  25       <div class="body"><p>The <a href="http://www.nuug.no/">Norwegian Unix User Group</a> is
  26 recording our montly presentation on video, and recently we have
  27 worked on improving the quality of the recordings by mixing the slides
  28 directly with the video stream.  For this, we use the
  29 <a href="http://dvswitch.alioth.debian.org/">dvswitch</a> package from
  30 the Debian video team.  As this require quite one computer per video
  31 source, and NUUG do not have enough laptops available, we need to
  32 borrow laptops.  And to avoid having to install extra software on
  33 these borrwed laptops, I have wrapped up all the programs needed on a
  34 bootable USB stick.  The software required is dvswitch with assosiated
  35 source, sink and mixer applications and
  36 <a href="http://www.kinodv.org/">dvgrab</a>.  To allow this setup to
  37 work without any configuration, I've patched dvswitch to use
  38 <a href="http://www.avahi.org/">avahi</a> to connect the various parts
  39 together.  And to allow us to use laptops without firewire plugs, I
  40 upgraded dvgrab to the one from Debian/unstable to get one that work
  41 with USB sources.  We have not yet tested this setup in a production
  42 setup, but I hope it will work properly, and allow us to set up a
  43 video mixer in a very short time frame.  We will need it for
  44 <a href="http://www.goopen.no/">Go Open 2009</a>.</p>
  45
  46 <p><a href="http://www.nuug.no/pub/video/bin/usbstick-dvswitch.img.gz">The
  47 USB image</a> is for a 1 GB memory stick, but can be used on any
  48 larger stick as well.</p>
