Accessing camera feed from PX2 via VideoCapture in OpenCV

I’m trying to process feed from the a-1 port with an ar-0231 camera using the Python bindings for OpenCV 3.1 module installed on the PX2 as per the instructions at

I noticed on other messages on this forum:

a string of arguments related to the camera properties was being passed to the VideoCapture function in C++ for the Jetson.

I was wondering if a similar procedure could be applied for accessing PX2 camera output I have and if so what the corresponding string I pass to VideoCapture should be?
