thanks for your reply tonfilm,
my problem with Trautner and the freeframe library is that I need to make a 64 bit aplication and they only work in 32 bits. So that’s why I was interested in this solution that kalle proposed - webcam (watchdog) - because it gives me an array of 2304 values after the node FrameDifference that I imagine might be the differences for every pixel.
This array comes from the Pipet node, and there’s is no reference or help to understand what this node does. I understand that the 2304 are RGB values, so in the end you would be handling only 768 values. And also 768 comes from multiplying the 32 value array and the 24 value array. So I understand this 2 ioboxes are to set the pixel definition maybe?
But I’m guessing, so it might be something else… Also I would need to know how are this values seen on the screen ( where is pixel 0;0 and so on).
So if I somehow understand this data I can develop myself a patch to detect movement in every region of the webcam.
So all input is welcome.
