AVPlayer Aspect Ratio - ios

Question

Ok so in my iOS app there is a screen with an AVPlayerViewController that takes care of playing videos. When this video is played it fills the entire screen however on some videos they video seems stretched as if it is being forced to fit. Is there any way to make the video fit the entire screen without losing the aspect ratio.
The code below is what I use to lay out the AVPlayerController. I figured some error here is the cause of this flaw in aspect ratio.

// Setup the view for stories
private func setupViews() {
view.backgroundColor = .clear
// Setup the blur view for loading
blurView = UIVisualEffectView(frame: view.frame)
blurView.effect = UIBlurEffect(style: .regular)
self.view.addSubview(blurView)
// Indicator for loading
let indicatorFrame = CGRect(x: view.center.x - 20, y: view.center.y - 20, width: 40, height: 40)
indicator = UIActivityIndicatorView(frame: indicatorFrame)
indicator.hidesWhenStopped = true
indicator.activityIndicatorViewStyle = .whiteLarge
blurView.contentView.addSubview(indicator)
// Setup the Progress bar
// spb = SegmentedProgressBar(numberOfSegments: allStories.count)
//// spb.frame = CGRect(x: 0, y: 1, width: self.view.frame.width, height: 9)
// self.view.addSubview(spb)
// spb.snp.makeConstraints { (make) in
// make.left.right.equalTo(view.safeAreaLayoutGuide)
// make.top.equalTo(view.safeAreaLayoutGuide.snp.top).offset(1)

// spb.delegate = self
// Player Controller
playerController = AVPlayerViewController()
playerController.showsPlaybackControls = false
self.addChildViewController(playerController)
// Image view for the story
imageView = UIImageView(frame: self.view.frame)
infoView = UIView(frame: self.view.frame)
infoView.backgroundColor = UIColor.clear
// The image view for the user of the current story
infoImageView = UIImageView()
self.view.addSubview(imageView)
self.view.addSubview(playerController.view)
// self.view.bringSubview(toFront: spb)
self.view.addSubview(infoView)
self.infoView.addSubview(infoImageView)
infoImageView.snp.makeConstraints { (make) in

}
infoImageView.layer.cornerRadius = 15
infoImageView.layer.masksToBounds = true
// The name for the user of the current story
infoNameLabel = UILabel()
infoNameLabel.backgroundColor = UIColor.black.withAlphaComponent(0.1)
infoNameLabel.textColor = UIColor.white
infoNameLabel.font = UIFont.boldSystemFont(ofSize: 18)
infoNameLabel.adjustsFontSizeToFitWidth = true
self.infoView.addSubview(infoNameLabel)
infoNameLabel.snp.makeConstraints { (make) in
make.left.equalTo(infoImageView.snp.right).offset(5)

make.width.equalTo(80)
}
// Time label for long ago the story was posted
infoTimeLabel = UILabel()
infoTimeLabel.backgroundColor = UIColor.black.withAlphaComponent(0.1)
infoTimeLabel.textColor = UIColor.white
self.infoView.addSubview(infoTimeLabel)
infoTimeLabel.snp.makeConstraints { (make) in
make.left.equalTo(infoNameLabel.snp.right).offset(5)

}
infoView.isUserInteractionEnabled = true
infoView.addGestureRecognizer(tapInfoView)
infoView.addGestureRecognizer(swipeInfoView)
infoTimeLabel.layer.cornerRadius = 10
infoTimeLabel.layer.masksToBounds = true
infoTimeLabel.textAlignment = .center
infoNameLabel.layer.cornerRadius = 10
infoNameLabel.layer.masksToBounds = true
infoNameLabel.textAlignment = .center
playerController.videoGravity = AVLayerVideoGravity.resizeAspectFill.rawValue
playerController.view.frame = view.frame
// spb.durations = durations
}
Any help is greatly appreciated

Answer 1

to keep the video aspect ratio in the defined view frame use
AVLayerVideoGravity.resizeAspect.
For the current case replace
playerController.videoGravity = AVLayerVideoGravity.resizeAspectFill.rawValue
to
playerController.videoGravity = AVLayerVideoGravity.resizeAspect

Answer 2

I am not sure about it but use this :
playerController.view.frame = view.bounds
Instead of this:
playerController.view.frame = view.frame
The AVLayerVideoGravity.resizeAspectFill.rawValue should do what is says and I never had a problem with it. However, I use the bounds instead of the frame and I remember getting problem when using the frame.
You also have AVLayerVideoGravity.resizeAspect.rawValue that will fit the video instead of filling it.
You can also try setting the frame before the video gravity.
