How to [window setAspectRatio:size] to a x,y+92 format

I'm creating an OS X application, and I have a video player in a web view that covers 100% of the height and width of a window The player has 16:9 format, plus 92px in height for ads and player controls.

So I want to set the window's aspect ratio, so that when a user resizes the window, the aspect ratio of the video is maintained, including the extra 92px in height.

at the moment, I used;

[window setAspectRatio:window.frame.size];

But obviously that also proportionally adds to the 92px constant and thus alters the video player's aspect ratio.

Can someone help me out here?

This is as simple as setting an object to be the window's delegate and implementing windowWillResize:toSize:. The window passes its proposed new size; the delegate can return a different size and the window will use that.

- (NSSize)windowWillResize:(NSWindow *)sender toSize:(NSSize)frameSize 
{
    CGFloat newWidth = frameSize.width;
    CGFloat newHeight = ((newWidth / 16) * 9) + 92;

    return (NSSize){newWidth, newHeight};
}
