iOS swift，視頻輸出不在 UIView 內居中

Question

所以我讓這個視頻在視圖的子層內播放，但視頻一直在UIView下方彈出，而不是在它里面有什么解決方案嗎？

import UIKit
import AVKit
import AVFoundation
import MediaPlayer

class ViewController: UIViewController {

    var player : AVPlayer? = nil
    var playerLayer : AVPlayerLayer? = nil
    var asset : AVAsset? = nil
    var playerItem: AVPlayerItem? = nil

    @IBOutlet weak var videoView: UIView!

    override func viewDidLoad() {
        super.viewDidLoad()

        let videoURLWithPath = "http://selevision9890-i.akamaihd.net/hls/live/219323/98906/1.m3u8"
        let videoURL = NSURL(string: videoURLWithPath)
        asset = AVAsset(URL: videoURL!) as AVAsset
        playerItem = AVPlayerItem(asset: asset!)
        videoView.frame = self.view.frame
        player = AVPlayer(playerItem: self.playerItem!)
        playerLayer = AVPlayerLayer(player: self.player)
        playerLayer!.frame = videoView.frame
        videoView.layer.addSublayer(self.playerLayer!)

        player!.play()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
}

正常視圖：

Answer 1

將此代碼移到viewDidAppear或viewWillAppear -在viewDidLoad ，框架尚不正確。 在viewDidLoad之后，將視圖調整為適合屏幕尺寸。

Answer 2

我不得不拋棄avplayer並使用avplayerviewcontroller，它很好用，謝謝大家

import UIKit
import AVFoundation
import AVKit

class ViewController: UIViewController {

    let avPlayerViewController = AVPlayerViewController()
    var avPlayer:AVPlayer?

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        let movieUrl:NSURL? = NSURL( string :"http://selevision9890-i.akamaihd.net/hls/live/219323/98906/1.m3u8")

        if let url = movieUrl{
            self.avPlayer = AVPlayer(URL : url )
            self.avPlayerViewController.player = self.avPlayer
        }
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    @IBAction func play(sender: AnyObject) {
        self.presentViewController(self.avPlayerViewController, animated: true) { 
            self.avPlayerViewController.player?.play()
        }
    }
}

我的解決方案是讓您的視圖像畫布一樣，基本上在其上繪制 AVPlayerViewController：

@IBOutlet weak var layerVideoView: UIImageView!
guard let url = Bundle.main.path(forResource: "santana", ofType: "mp4") else { return debugPrint("video not found") }
let path = URL(fileURLWithPath: url)

let player = AVPlayer(url: path)
let playerController = AVPlayerViewController()
playerController.player = player
playerController.view.frame = CGRect(x: layerVideoView.frame.origin.x, y: layerVideoView.frame.origin.y, width: layerVideoView.frame.width, height: layerVideoView.frame.height)
self.addChild(playerController)
self.view.addSubview(playerController.view)

LayerVideoView 是一個圖像視圖，但如果適合，您可以只使用 UIView。 將 Storyboard 中的約束添加到您的視圖中很重要，因為您的視頻播放器將模仿您的視圖的形狀。

設置PlayerLayer視頻重力

let videoURLWithPath = "http://selevision9890-i.akamaihd.net/hls/live/219323/98906/1.m3u8"
let videoURL = NSURL(string: videoURLWithPath)
playerItem = AVPlayerItem(url: videoURL! as URL)
player = AVPlayer(playerItem: self.playerItem!)
playerLayer = AVPlayerLayer(player: self.player)
playerLayer.frame =  videoView.frame
playerLayer.backgroundColor = UIColor.black.cgColor
playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill
videoView.layer.addSublayer(self.playerLayer!)
player!.play()

Answer 5

我有類似的問題。 我去像這樣子類化UIView：

import UIKit

class VideoPlayerView: UIView {
var playerLayer: CALayer?

override func layoutSublayersOfLayer(layer: CALayer) {
    super.layoutSublayersOfLayer(layer)
    playerLayer?.frame = self.bounds
  }
}

並用它來設置這樣的視頻：

@IBOutlet weak var videoPlayer: VideoPlayerView!

func setupVideoOnView() {
    var player = AVPlayer(URL: mediaURL! as NSURL)
    let playerLayer = AVPlayerLayer(player: player)

    playerLayer.frame = self.videoPlayer.bounds
    playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill
    self.videoPlayer.layer.addSublayer(playerLayer)
    self.videoPlayer.playerLayer = playerLayer

}

那是用錯誤的框架欺騙了。
