AVPlayer get rid of black bars/background at top & bottom (Swift)

Question

Quick question, does anybody know how i can get rid of the black bars at the top and bottom of my video? I just started using AVPlayer and i'm just removing codes here and there in attempt to remove the black layers. Appreciate those who can help me, Thanks!

UIViewController

import UIKit
import AVKit
import AVFoundation
private var looper: AVPlayerLooper?

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        let path = Bundle.main.path(forResource: "Innie-Kiss", ofType:"mp4")
        let player = AVQueuePlayer(url: URL(fileURLWithPath: path!))
        looper = AVPlayerLooper(player: player, templateItem: AVPlayerItem(asset: AVAsset(url: URL(fileURLWithPath: path!))))
        let controller = AVPlayerViewController()
        controller.player = player
        let screenSize = UIScreen.main.bounds.size
        let videoFrame = CGRect(x: 0, y: 200, width: screenSize.width, height: (screenSize.height - 130) / 2)
        controller.view.frame = videoFrame
        self.view.addSubview(controller.view)
        player.play()
    }

}

Answer 1

You need to set the videoGravity of the AVLayer. The default value is .resizeAspect which will preserve the aspect ratio with black bars on top/bottom or left/right. What you want is .resize

The AVLayer you need to set the videoGravity on is the layer property of your AVPlayer.

Answer 2

#import AVKit

var playerController = AVPlayerViewController()
playerController.videoGravity = .resizeAspect
 /*playerController.videoGravity = .resizeAspectFill*/
playerController.view.backgroundColor = UIColor.white //set color as per super or custom view.

Note: If you set the videoGravity of the AVPlayerViewController. The default value is .resizeAspect then it is possible to visibility of black color(default) in background if you wants this color would similar to your super view's color then you must set superview's or custom view's color to your playercontroller's view background color.

*Example:Suppose super view's or custom view's background color is white then playerController view's background color must be set as playerController.view.backgroundColor = UIColor.white *

Note :playerController's backgroundColor should not be set as UIColor.white ,always. It must me set as super view' background color.

If you set playerController.videoGravity = .resizeAspectFill then it will fill the player content to super view or custom view, here also no black color would be shown. So choose either .resizeAspect  or resizeAspectFill as per your requirements.
