try using "motion", I've only used it with a webcam, it generates jpeg images at a speed you set. It's a bit tricky to set up, needs lots of trial and error. Dave P
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.
Ok, I had a quick look, it seems the thing. Thanks :-) "motion detector" seems to be the key word. Now I found some articles: https://en.wikipedia.org/wiki/Motion_detection https://en.wikipedia.org/wiki/Motion_estimation https://en.wikipedia.org/wiki/Motion_detector What I don't see there is a list of software. It appears that it is mostly done by electronic detectors, software methods are just only mentioned. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
