Can Aspect Ratio be used with AVPlayer video player? about pinlayout

[lucdion]

Yes, you should layout your views either from UIView. layoutSubviews() or UIViewController.viewDidLayoutSubviews(). This way when the size of your parent view change your subviews layout will be adjusted. This will also handle device orientation change.

Hi @netgfx, aspectRatio (and all other PinLayout's methods) can be applied to any view that inherits from UIView.

PinLayout's don't use constraints, whenever you want to change the size/position of a view, you have to re-layout your view to update either its position, size or both.

So the flow would go like this: load video > get width&height > set dimensions to playerViewControler view > call view.layoutSubviews()
?

Sorry, I've never used the AVPlayerViewController, but most UIViewController inherited class comes with their own UIView (UITableViewController, UICollectionViewController, ...). So it is not really easily possible to control how they layout their view (and subviews), I'm surprise that it don't correctly handle its movie aspectRatio.

If you want to have more control you should probably use AVPlayer. See https://stackoverflow.com/a/31277658

Even in the example that you send it uses let playerViewController = AVPlayerViewController() to contain the AVPlayer which is the underlying player.

In terms of PinLayout I'm mostly interested on how to change width and height dynamically. Since I found that after the movie is loaded I can get its width and height via self.player.view.layer.visibleRect.width & self.player.view.layer.visibleRect.height

So is there away to dynamically change the .pin.height() of that self.player.view? (Initially I set it to .pin.height(50%)

You can use any PinLayout's sizing method https://github.com/mirego/PinLayout#width-height-and-size on any view, including the player.view.

You can also use the aspectRatio method to force the aspect ratio (https://github.com/mirego/PinLayout#aspect-ratio)

let movieAspectRatio = self.player.view.layer.visibleRect.width / self.player.view.layer.visibleRect.height
self.player.view.pin.width(100%).aspectRatio(movieAspectRatio)

ok good to know, that helps.

Can I call self.player.view.pin.width(100%).aspectRatio(movieAspectRatio) from any part in the class or does it have to be inside the layoutSubviews() function?
