Hello. Is there any way to check if my camera is enabled (I don't mean available and I know that the light of computer is on when camera is on),but I'm writing a program with many files and functions and I want to check if camera is enabled -> do this ,if not -> do that ? So, I want to have a function to tell me if camera is enabled or not and use it to check other things in my program, but I want to know if can be happen.

Ubuntu 18 , Python 3 Thanks.

what do you mean, "enabled"? OpenCV can't know if any video device in your system is currently being used. that's not OpenCV's purpose.

the only way to check is to try it out:

VideoCapture cap;
bool ok = cap.open(0);
