Video AVPlayerLayer not filling PlayerView

[CristianoCastro]

I have a video with 360x480 and am playing it on an iPhone4S, but I can see a bit of the underlying imageview image (mainImageView from ASMediaFocusController). Through debug I removed the image and painted the imageview's background red so you can see better what is happening (notice the vertical red near the edges):

The PlayerView has the correct frame, but it's layer isn't filling it, we need to set videoGravity = AVLayerVideoGravityResizeAspectFillfor it to fill completely the PlayerView. Something like:

- (void)showPlayerWithURL:(NSURL *)url
{
    self.playerView = [[PlayerView alloc] initWithFrame:self.mainImageView.bounds];
    ((AVPlayerLayer *)(self.playerView.layer)).videoGravity = AVLayerVideoGravityResizeAspectFill;
   ...

Doing that the video fills the entire PlayerView as expected.
