Sharing image data with OpenCV on the same pi as Hyperion?

Is there a way to access the hyperion captured image data from a separate application on the same pi running Hyperion. With HyperionNG running I cannot access the capture device. My goal is to use openCV to analyze the image and react to items that appear. I could split the signal and run it all on a separate pi, but was hoping I could just stay all on my pi4 or at the very least somehow connect openCV on another pi to the forwarder of the Hyperion pi.
