[tech] webcams

[James Andrewartha]

The EE workship very kindly repaired the cable on the colour webcam,
however as you can see there's something not quite right about it. I
changed the structure of the archives slightly they're now divided by
yearmonth/day/hour, and I've update the archive webpage. I also installed
mencoder on mussel and played around with it to create movies from the
image archives - currently I'm using

mencoder -info name="Colour Webcam $date":subject="UCC Colour Webcam
archive for $date":srcform="UCC Colour webcam jpegs" -noskip -o
colour-$date.avi -of avi -ovc lavc -lavcopts vcodec=mpeg4 mf://\*/\*.jpg
-mf type=jpeg

but there's a whole bundle of options to tweak.
