i need to analyze a video input signal very roughly, like brightness/luminosity of black/white in low resolution an framerate (some frames per second). actually i want to detect changes or movement through the picture/screen.
I made a very simple brightness analyzer for PDP a couple of days ago. It outputs the average of the red, green and blue components as fkoats in each frame. Haven't published it yet, because it was a quick and dirty hack on a late night. I expect to rush it out in a couple of days...
btw some objects of pdp cannot be created (pdp_blur, pdp_motion_phase). should i change to a newer version? now i am using 0.10.1.
Add the abstractions directory of PDP to your pd -path ... (best done in your ~/.pdrc file).
and last question: pdp_xv shows an error: no xv port available. is this a software problem, or does my tv-card not support this?
XV is an extension to X, and has nothing to do with your tv card. Check your XFree86 configuration.
