Ambilight (newbie here)

Hello Everyone!
Complete newbie here so any help will be greatly appreciated!

I have a Raspberry pi 2 running osmc, and am currently starting my ambilight project.
I have attached ws2811 leds to the rear of my television, and have uploaded code to my arduino to run the Leds.

Is there any chance boblight will be able to read video footage provided to it via a rca to usb adaptor? (video to usb)
And then output via serial still?
Any help would be awesome!

Thanks you all!
