setFrame not working properly for AVCaptureVideoPreviewLayer

I am trying to add a AVCaptureVideoPreviewLayer into my view like this

[captureVideoPreviewLayer setFrame:CGRectMake(10.0f,10.0f,300.0f,300.0f)];
[self.view.layer addSublayer:captureVideoPreviewLayer];

but it doesnt seem to follow the CGRectMake, the layer is 300 in height but not in width, I am not sure why!

The solution was simple, I just had to add captureVideoPreviewLayer.videoGravity = AVLayerVideoGravityResizeAspectFill; and that fixed the problem.

Make sure you are assigning a view outlet to captureVideoPreviewLayer, better to access like self.captureVideoPreviewLayer. If you are doing things in order then setting the frame should work using CGRectMake. I have been using it to change the size of preview layer like this.

  self.captureVideoPreviewLayer.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);

It seems, as if your view has the wrong dimension for the layer. For this update the size of the view at least to the desired rect:

[self.view setBounds:CGRectMake(10.0f,10.0f,300.0f,300.0f)];
