Any info available on the overlay in win32?

I want to be able to pull rgb information out of the overlay on the fly. Any information available on the code needed in c++ to accomplish this? I thought I would check here first since I have no doubt a few of you have done something similar.

The goal is to be able to calculate the relative intensity of each frame on the fly as you play back any video file (it should be independent of codec if I use the overlay, right?). I've built the functions for calculating the intensity, I just don't know how to access the overlay/frame buffer.
