openCV output video for use in 3rd party application

I am working on a openCV based robotic video camera.
What I can’t seem to find is any information on how to make the video feed available to the system.

So currently my ofApp attaches the usb video camera, I run some openCV and serial operations… now I would like to release the original video feed as a system output (wdm or such) so that My video mixing software can pick it up as an input.

I’m a bit of a newbie, so please excuse me if this is clearly listed int the api (I did look). I am posting to this thread here because I suspect this is beyond the average video usage.
