AVPlayer layer inside a view does not resize when UIView frame changes

Question

I have a UIView which contains an AVPlayer to show a video. When changing orientation, I need to change the size and location of the video.

I'm not very experienced with resizing layers, so I'm having problems making the video resize.

I start by creating the AVPlayer and adding its player to my videoHolderView's layer:

NSURL *videoURL = [NSURL fileURLWithPath:videoPath];
self.avPlayer = [AVPlayer playerWithURL:videoURL];

AVPlayerLayer* playerLayer = [AVPlayerLayer playerLayerWithPlayer:self.avPlayer];
playerLayer.frame = videoHolderView.bounds;
playerLayer.videoGravity = AVLayerVideoGravityResizeAspect;
playerLayer.needsDisplayOnBoundsChange = YES;

[videoHolderView.layer addSublayer:playerLayer];
videoHolderView.layer.needsDisplayOnBoundsChange = YES;

Then, at a later point, I change the size and location of the videoHolderView's frame:

[videoHolderView setFrame:CGRectMake(0, 0, 768, 502)];

At this point, I need the avPlayer to resize to these same dimension. This doesn't happen automatically - the avPlayer stays at it's small size within the videoHolderView.

If anyone can help, I'd really appreciate any advice.

Thanks guys.
