The webcam-movie.avi video was built from a lot of static jpeg images
that were previously in /nfs/media/images/webcam-realtime/ (deleted now).
I was getting a bit annoyed that xscreensaver kept using these, so I
decided to turn them into a video.  After much reading of MPlayer/MEncoder's
incredibly verbose manual, I found an example at the end of the file: use the
'mf://' method.  I did this:

  mencoder "mf://*.jpg" -mf fps=5 -o ~/output.avi -ovc lavc -lavcopts \
  vcodec=mpeg4

The output file is a 5 fps MPEG4 video.
