Custom Video Cropping

[baseljd]

Is there a way to change the crop to crop from the top instead of from the center ?

I tried changing

- (SCIOPixelBuffers *)renderIOPixelBuffersWithCI:(SCIOPixelBuffers *)pixelBuffers {
....
                result = [result imageByCroppingToRect:CGRectMake(result.extent.origin.x, frame.origin.y, _outputBufferSize.width, _outputBufferSize.height)];

//changed to

                result = [result imageByCroppingToRect:CGRectMake(result.extent.origin.x, frame.origin.y - 200, _outputBufferSize.width, _outputBufferSize.height)];

....
}

I also tried changed

- (CIImage *)renderedCIImageInRect:(CGRect)rect {
....

filteredImage = [filteredImage imageByCroppingToRect:CGRectMake(extent.origin.x + xImage, extent.origin.y, extent.size.width, extent.size.height)];

//changed to

filteredImage = [filteredImage imageByCroppingToRect:CGRectMake(extent.origin.x + xImage, extent.origin.y -200, extent.size.width, extent.size.height)];

....
}

But it's not working
