macOS How to change the Aspect ratio of a QTMovie

[sabharwal81]

I have a QTMovie (added as a layer to NSView) like this

QTMovie *mMovie = [QTMovie movieWithFileathName error: &myErr];
QTMovieLayer *movieLayer = [QTMovieLayer layerWithMovie:mMovie];
[basketView setLayer:movieLayer]; // basketView is an NSView.

Now how do i change the aspect ratio to say 5:3, 16:9, 16:10 etc.

You could try playing with the layer's contentsGravity property and adjusting the frame to be of the ratio you want.
