Only grayscale image is shown

It seems that only gray image is displayed in the camera view.

I am using Swift 4.

Yes. you can rewrite the codes converting camera image into gray with anything you want.

And sorry, this project is old and I didn’t have time to migrate to Swift 4...

I mean I didn't really change to code, with

output.videoSettings = @{(NSString *)kCVPixelBufferPixelFormatTypeKey : @(kCVPixelFormatType_32BGRA)};

and

Mat mat = Mat(height, width, CV_8UC4, base);

but it still displays grayscale outputs :(

even using the official demo
