Javacv: Black Sidebars appear on the captured image

[ahmedaomda]

I'm using OpenCVFrameGrabber to grabbe frames from my USB cam but the grabbed image has black bars appears on each side but when i try Windows Camera app it doesn't have these bars ,Is there is some configs I'm missing ?

OpenCVFrameGrabber grabber = new OpenCVFrameGrabber(0);
grabber.setImageWidth(captureWidth);
grabber.setImageHeight(captureHeight);
grabber.start();

Frame capturedFrame = grabber.grab();
Java2DFrameConverter converter = new Java2DFrameConverter();
converter.convert(capturedFrame);

Could you try VideoInputFrameGrabber instead? It usually works better than OpenCV on Windows...

How did you solve it?

I just replaced the OpenCVFrameGrabber with VideoInputFrameGrabber and it did the trick I think it handles the aspect ration internally
