Screen recording and Nvidia acceleration

is there a screen grabber that uses NVFBC?

Currently I'm using DXGI with this:

./gst-launch-1.0 dxgiscreencapsrc ! videoscale method=0 ! videoconvert ! 

but it consume a bit of CPU, I want to lower the CPU utilization.

I don't need big quality or sync, I only need to record the screen to 
get colors on an X,Y point of the screen.
So I don't really need to capture all the screen. I only need to get the 
color of the screen in some X,Y points of the screen.

Any suggestions on how to do it and lower the CPU usage?
Is there some options to lower the cpu usage by reducing the quality of 
the screen capture or with some other tricks?
