Hi,
I have been trying to photograph the Perseids (shooting stars). I got some on my SLR camera. Not good quality, but hey, it is the first time I do it.
Just for kicks I set up another camera doing a video of the sky for as long as it would go, which turned to be till the video file was 2 GB (FAT memory card). At 15 frames per second.
It appears to be 45 minutes of full black, which is not a surprise. However, I wonder if there is some software in Linux to scan a video and signal somehow when the scene changes. The sort used for security, when a person comes into focus, perhaps. I can not view 45 minutes of black, I will get bored within a minute ;-)

I second the recommendation of 'motion'. The project is undergoing something of a rebirth, so start at http://www.lavrsen.dk/foswiki/bin/view/Motion/WebHome and follow it to https://github.com/Motion-Project/motion for actual code. As a result of the project restructuring, up-to-date source and binaries should eventually make it into distro repositories. Do join the mailing list for any queries and to keep up to date. It will sort out whatever video/photo format you have and want, once you understand its quirks.
