I’ve been trying to use my mac’s internal webcam with OpenCV C++ VideoCapture class by VideoCapture cap(0) =\> I’ve been told 0 means the default internal camera, but i keep getting errors.  
I’ve given both terminal and iTerm access to the Camera on my Mac’s Preferences, but vscode still throws me this error.
