Hi all,

When I try to run:

cv::VideoCapture cap;;

I get the error:


OpenCV: not authorized to capture video (status 0), requesting...
OpenCV: camera failed to properly initialize!

It's my first time using OpenCV4 (4.1.0) with C++11 and Xcode.

Any help is appreciated.

Thanks, Tiger

Go to System Preferences->Privacy->Camera and check your privacy permissions.

Hi eshirima, I have done that and all that requested camera access are granted camera permission. I think the issue is that my xcode commandline tool project is not requesting camera access properly.
