Apply filter to live camera on button???

Hello,
I am trying to apply filter to live camera on pressing button.
IBOutlet UIView *camImageView;
GPUImageVideoCamera *videoCamera;
if (button.selected == NO)
{
button.selected = YES;
[videoCamera removeTarget:(GPUImageView *)self.camImageView];
if (filter == nil)
filter = [[GPUImageSepiaFilter alloc] init];
[filter addTarget:(GPUImageView *)self.camImageView];
[videoCamera addTarget:filter];
videoCamera.outputImageOrientation = UIInterfaceOrientationPortrait;
}
else
{
button.selected = NO;
[filter removeTarget:(GPUImageView *)self.camImageView];
[videoCamera removeTarget:filter];
[videoCamera addTarget:(GPUImageView *)self.camImageView];
videoCamera.outputImageOrientation = UIInterfaceOrientationPortrait;
}Filter GPUImageSepiaFilter applied but camera rotates to landscape position and videoCamera.outputImageOrientation = UIInterfaceOrientationPortrait; doesn't help.
And sometimes after pressing button, it is showing black screen.
It it possible to apply filter by pressing button or I should start/stop camera?
I would be interested in a solution for this as well. Anyone managed to achieve this?
