DIY Ambilight clone with Hyperion and Openelec. : raspberry_pi

The guides I've read take the hdmi signal, [1] split (duplicate) it, [2] convert it to composite video, [3] run that through a "grabber" that plugs into USB on the pi, and then hyperion does the rest, basically. So, anything you would plug into the grabber would be what the software used for the LED colors. In theory, yeah, it seems plausible to point a camera at a screen and run the AV output into the grabber.
