My web cams are pretty old, fairly low res, but have been running for quite a few years. They need to be power-cycled now and again, which the Pis handle most of the time, detecting when they appear to be hung for the most part. There are two web cam pages, a "top" one showing the current (within 5 minutes) image from both cams... (when everything works):
At the bottom of that page is a link to a "calender" of vids of the daily sets of images collected into time lapse mp4s. The North-facing one sometimes shows some interesting cloud movements. Occaisionally the South-facing one of our garden and shed (and weather station) will pick up a critter (sometimes the 2-legged variety) walking through the yard.
The calendars are chained so one can navigate back in time. I still get a kick out of the time lapse. I keep thinking I should do an annual one, but never found the time. (I think the light and dark days might render it less than fluid to view.)
Yeah, I know ... Terrible siting for an anemometer, but we're surrounded by very tall trees - so it's a lost cause!
The mp4s are generated on a Raspberry Pi which does a suprisingly good job. As I understand it, ffmpeg leverages some hardware - and they build considerably faster than they used to on my web server host.
