Hello,
I have a dream. I want my software, connected to a webcam, be able to draw a pixel on the window when something, say a red led, is moving in front of it. So that I could draw moving this led.
I suspect it is not difficult in principle but several library are necessary among which a motion detection one.
Does anybody have a suggestion?
Thanks,
Luigi

Hi Luigi,
I use a GPL software called simply motion. It is a simple, but very powerful tool.
I'm not sure if it can work on windows or if it can be used as library, but perhaps you can get at least some ideas... The sources are just a few files. As far as I can tell it uses v4l and sdl.

Sorry, I never tried with more than one camera, so I can't really help you...
