Face detection example fails on Mac OSX with built-in iSight

The face detection example fails on Mac OSX, since the camera parameter must be set 0 instead of 1 like in the other examples.
I don't know if it is just me or it is a common issue, but I'm writing this here to support people that could face the same problem.

@zankich can you look at this please?

@pasine Did you ever figure this out?

@stewart, @zankich, @rafmagana, @solojavier could any of you guys with macs try this out?

I just tested and it's true that face example is not working, if I run as it is I get this error:

Warning, camera failed to properly initialize!
Cleaned up camera.

If I change to use camera = 0, then I get this:

The camera is ready!

I was missing a file.... Changing camera: 0, makes the example work... Fixed here: 95fe379

edgarsilva commented

What file?

solojavier commented

haarcascade_frontalface_alt.xml

edgarsilva commented

But it is included in the example and referenced in the docs right? that it should be included...

FreeEye commented

if macOS set like this "cap = cv2.VideoCapture(0)"
