Does anyone know where I can get some software that will analyze a video stream for changes between two frames? What I’m looking for is an application that will watch a video stream for changes and then highlight those changes. Bonus points for something open-source or that runs under some Linux variant.
Thanks and regards

I found this on sourceforge if it helps. Not sure if it is what you need but it does run on Linux and is open source.
Search on www.sourceforge.net for more, maybe.

Thank you. I’ll check this to see if I can get it to work.

ZipperJJ That’s just an encoding library, no?
You’re kinda vague there Testy, but it sounds to me like you’re looking for more of a webcam motion detection/security camera package, which would be something like motion or gspy.
This site has instructions on how to use a Windows app called Dorgem that also seems fairly decent.

Thank you. Yeah, motion detection was what I was looking for although I hadn’t thought of it in those terms. I’ll give these a try. What I wanted to do was experiment with the various parameters of comparing two images. How big a spot to compare? Black and white or color? etc. I don’t have a serious need for this or anything, just experimenting.
Thanks again

Thanks again for pointing me in the right direction. The Motion software was almost exactly what I was looking for. Now I have to pick some cameras. I would like to use D-Link as I can get those locally but they don’t seem to support LINUX/UNIX at all. X-10 was another one but they seem entirely too hokey. The web site is like a used-car advertisement on late-night TV. 
Thanks again
