Constant camera grabbing with OpenCV & Python multiprocessing

Capturing video from two cameras in OpenCV at once
How do you capture video from two or more cameras at once (or nearly) with OpenCV, using the Python API? I have three webcams, all capable of video streaming, located at /dev/video0, /dev/video1, and /dev/video2. Using the tutorial as an example, capturing images from a single camera is simply: And this works…
