usage of GPU in Raspberry pi

How can I process video using the Videocore IV GPU in Raspberry pi?

Please define "process video".

omxplayer uses GPU to display video.

I need to detect the motion of a human being using a web camera, analyze it and move the camera according to his motion. When I've used the processor for the implementation of the algorithm, it lags. That's why, I've planned to use the dedicated GPU in the Pi.
How can I acces the GPU according to my use?

Check the comments , especially those from Dom.

If this isn't useful for you , i guess your only remaining option is
to write custom GPU assembly , which will be very complicated.

First :
http://www.broadcom.com/support/
Check both links under "VideoCore Graphics Resources"

Second :
www.github.com/hermanhermitage/videocoreiv
Lots of information , code , and links (mostly based on
reverse engineering).

Look at all the resources and see for yourself which approach
makes the most sense for your application.
