The directory /home/bnode/baltimorenode.org/public/images/webcam-backup is symbolically linked to /home/bnode/webcam-backup.
When executed from the directory containing the webcam still, this command will create a time lapse video.
mencoder -nosound mf://*.jpg -mf w=640:h=480:type=jpg:fps=5 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=1000000 -o time_lapse-test.avi
