如何在 Swift 中使用 AVPlayerViewController (AVKit) 播放視頻

Question

如何在 Swift 中使用 AV Kit Player View Controller 播放視頻？

override func viewDidLoad() {
        super.viewDidLoad()
        let videoURLWithPath = "http://****/5.m3u8"
        let videoURL = NSURL(string: videoURLWithPath)
        playerViewController = AVPlayerViewController()

        dispatch_async(dispatch_get_main_queue()) {
            self.playerViewController?.player = AVPlayer.playerWithURL(videoURL) as AVPlayer
        }
    }

Answer 1

斯威夫特 3.x - 5.x

必需：導入 AVKit ，導入 AVFoundation

即使使用 AVPlayer 也需要 AVFoundation 框架

如果你想使用AVPlayerViewController ：

let videoURL = URL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")
let player = AVPlayer(url: videoURL!)
let playerViewController = AVPlayerViewController()
playerViewController.player = player
self.present(playerViewController, animated: true) {
    playerViewController.player!.play()
}

或只是AVPlayer ：

let videoURL = URL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")
let player = AVPlayer(url: videoURL!)
let playerLayer = AVPlayerLayer(player: player)
playerLayer.frame = self.view.bounds
self.view.layer.addSublayer(playerLayer)
player.play()

最好將此代碼放入方法中： override func viewDidAppear(_animated: Bool)或之后的某處。

目標-C

AVPlayerViewController :

NSURL *videoURL = [NSURL URLWithString:@"https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"];
AVPlayer *player = [AVPlayer playerWithURL:videoURL];
AVPlayerViewController *playerViewController = [AVPlayerViewController new];
playerViewController.player = player;
[self presentViewController:playerViewController animated:YES completion:^{
  [playerViewController.player play];
}];

或只是AVPlayer ：

NSURL *videoURL = [NSURL URLWithString:@"https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"];
AVPlayer *player = [AVPlayer playerWithURL:videoURL];
AVPlayerLayer *playerLayer = [AVPlayerLayer playerLayerWithPlayer:player];
playerLayer.frame = self.view.bounds;
[self.view.layer addSublayer:playerLayer];
[player play];

Answer 2

試試這個，絕對適用於Swift 2.0

 let player = AVPlayer(URL: url)
    let playerController = AVPlayerViewController()

    playerController.player = player
    self.addChildViewController(playerController)
    self.view.addSubview(playerController.view)
    playerController.view.frame = self.view.frame

    player.play()  

Answer 3

嘗試這個

var player:AVPlayer!
var avPlayerLayer:AVPlayerLayer = AVPlayerLayer(player: player)
avPlayerLayer.frame = CGRectMake(your frame)
self.view.layer .addSublayer(avPlayerLayer)
var steamingURL:NSURL = NSURL(string:playerURL)
player = AVPlayer(URL: steamingURL)
player.play()

Swift 3.0 完整源代碼：

import UIKit
    import AVKit
    import AVFoundation

    class ViewController: UIViewController,AVPlayerViewControllerDelegate
    {
        var playerController = AVPlayerViewController()


        @IBAction func Play(_ sender: Any)
        {
            let path = Bundle.main.path(forResource: "video", ofType: "mp4")

            let url = NSURL(fileURLWithPath: path!)

            let player = AVPlayer(url:url as URL)

            playerController = AVPlayerViewController()


            NotificationCenter.default.addObserver(self, selector: #selector(ViewController.didfinishplaying(note:)),name:NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: player.currentItem)

            playerController.player = player

            playerController.allowsPictureInPicturePlayback = true

            playerController.delegate = self

            playerController.player?.play()

            self.present(playerController,animated:true,completion:nil)
        }

        func didfinishplaying(note : NSNotification)
        {
            playerController.dismiss(animated: true,completion: nil)
            let alertview = UIAlertController(title:"finished",message:"video finished",preferredStyle: .alert)
            alertview.addAction(UIAlertAction(title:"Ok",style: .default, handler: nil))
            self.present(alertview,animated:true,completion: nil)
        }


        func playerViewController(_ playerViewController: AVPlayerViewController, restoreUserInterfaceForPictureInPictureStopWithCompletionHandler completionHandler: @escaping (Bool) -> Void) {
                let currentviewController =  navigationController?.visibleViewController

                if currentviewController != playerViewController
                {
                    currentviewController?.present(playerViewController,animated: true,completion:nil)
                }


            }
    }

這僅適用於Xcode 7

轉到.h文件並導入AVKit/AVKit.h和AVFoundation/AVFoundation.h 。 然后轉到.m文件並添加以下代碼：

NSURL *url=[[NSBundle mainBundle]URLForResource:@"arreg" withExtension:@"mp4"];
AVPlayer *video=[AVPlayer playerWithURL:url];
AVPlayerViewController *controller=[[AVPlayerViewController alloc]init];
controller.player=video;
[self.view addSubview:controller.view];
controller.view.frame=self.view.frame;
[self addChildViewController:controller];
[video play];

首先，您必須在視圖控制器中全局定義 2 個變量。

var player: AVPlayer!
var playerViewController: AVPlayerViewController!

在這里，我將播放器添加到所需的視圖中。

@IBOutlet weak var playerView: UIView!

然后將以下代碼添加到viewDidLoad方法中。

let videoURL = URL(string: "videoUrl")
self.player = AVPlayer(url: videoURL!)
self.playerViewController = AVPlayerViewController()
playerViewController.player = self.player
playerViewController.view.frame = self.playerView.frame
playerViewController.player?.pause()
self.playerView.addSubview(playerViewController.view)

如果您沒有全局定義player和playerViewController ，您將無法嵌入播放器。

Answer 7

使用 MPMoviePlayerController ：

 import UIKit
 import MediaPlayer

 class ViewController: UIViewController {

     var streamPlayer : MPMoviePlayerController =  MPMoviePlayerController(contentURL: NSURL(string:"video url here"))
     override func viewDidLoad() {
         super.viewDidLoad()
         streamPlayer.view.frame = self.view.bounds
         self.view.addSubview(streamPlayer.view)

         streamPlayer.fullscreen = true
         // Play the movie!
         streamPlayer.play()
}
}

使用 AVPlayer ：

import AVFoundation

var playerItem:AVPlayerItem?
var player:AVPlayer?

override func viewDidLoad() {
        super.viewDidLoad() 
      let url = NSURL(string: "url of the audio or video") 
      playerItem = AVPlayerItem(URL: url!)
      player=AVPlayer(playerItem: playerItem!)
      let playerLayer=AVPlayerLayer(player: player!)
      playerLayer.frame=CGRectMake(0, 0, 300, 50)
      self.view.layer.addSublayer(playerLayer)
}

我有一個播放按鈕來處理按鈕點擊。

playButton.addTarget(self, action: "playButtonTapped:", forControlEvents: .TouchUpInside)

func playButtonTapped(sender: AnyObject) {
        if player?.rate == 0
        {
            player!.play()
            playButton.setImage(UIImage(named: "player_control_pause_50px.png"), forState: UIControlState.Normal)
        } else {
            player!.pause()
            playButton.setImage(UIImage(named: "player_control_play_50px.png"), forState: UIControlState.Normal)
        }
    }

我添加了一個監聽 AVPlayerItemDidPlayToEndTimeNotification 的觀察者。

override func viewWillAppear(animated: Bool) {
        NSNotificationCenter.defaultCenter().addObserver(self, selector: "finishedPlaying:", name: AVPlayerItemDidPlayToEndTimeNotification, object: playerItem)
    }

override func viewWillDisappear(animated: Bool) {
        NSNotificationCenter.defaultCenter().removeObserver(self)
    }

視頻/音頻播放完成后，重置按鈕圖像和通知

  func finishedPlaying(myNotification:NSNotification) {
        playButton.setImage(UIImage(named: "player_control_play_50px.png"), forState: UIControlState.Normal)

        let stopedPlayerItem: AVPlayerItem = myNotification.object as! AVPlayerItem
        stopedPlayerItem.seekToTime(kCMTimeZero)
    }

iOS10/Swift3/Xcode 8 中的錯誤（？！）？

if let url = URL(string: "http://devstreaming.apple.com/videos/wwdc/2016/102w0bsn0ge83qfv7za/102/hls_vod_mvp.m3u8"){
    let playerItem = AVPlayerItem(url: url)
    let player = AVPlayer(playerItem: playerItem)
    let playerLayer = AVPlayerLayer(player: player)
    playerLayer.frame=CGRect(x: 10, y: 10, width: 300, height: 300)
    self.view.layer.addSublayer(playerLayer)
}

不起作用（空矩形...）

這有效：

if let url = URL(string: "http://devstreaming.apple.com/videos/wwdc/2016/102w0bsn0ge83qfv7za/102/hls_vod_mvp.m3u8"){

            let player = AVPlayer(url: url)
            let controller=AVPlayerViewController()
            controller.player=player
            controller.view.frame = self.view.frame
            self.view.addSubview(controller.view)
            self.addChildViewController(controller)
            player.play()
        }

這在Swift 5 中對我有用

剛剛從Sample Videos向項目添加了示例視頻

使用以下 swift 代碼示例添加了用於播放來自網站和本地的視頻的操作按鈕

import UIKit
import AVKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        //TODO : Make Sure Add and copy "SampleVideo.mp4" file in project before play
    }

    @IBAction func playWebVideo(_ sender: Any) {

        guard let url = URL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4") else {
            return
        }
        // Create an AVPlayer, passing it the HTTP Live Streaming URL.
        let player = AVPlayer(url: url)
        let controller = AVPlayerViewController()
        controller.player = player
        present(controller, animated: true) {
            player.play()
        }
    }

    @IBAction func playLocalVideo(_ sender: Any) {

        guard let path = Bundle.main.path(forResource: "SampleVideo", ofType: "mp4") else {
            return
        }
        let videoURL = NSURL(fileURLWithPath: path)

        // Create an AVPlayer, passing it the local video url path
        let player = AVPlayer(url: videoURL as URL)
        let controller = AVPlayerViewController()
        controller.player = player
        present(controller, animated: true) {
            player.play()
        }
    }

}

Answer 11

let videoUrl = //URL: Your Video URL

//Create player first using your URL
let yourplayer = AVPlayer(url: videoUrl)

//Create player controller and set it’s player
let playerController = AVPlayerViewController()
playerController.player = yourplayer


//Final step To present controller  with player in your view controller
present(playerController, animated: true, completion: {
   playerController.player!.play()
})

  @IBAction func buttonPressed(_ sender: Any) {
    let videoURL = course.introductionVideoURL
    let player = AVPlayer(url: videoURL)
    let playerViewController = AVPlayerViewController()
    playerViewController.player = player

    present(playerViewController, animated: true, completion: {

        playerViewController.player!.play()
    })

// 這里的課程包含一個模型文件，在里面我已經給出了 url，所以我使用 course 函數從模型調用函數。

// 也是 IntroductionVideoUrl 是我在 model 中聲明的 URL。

 var introductionVideoURL: URL

或者，您可以使用以下代碼而不是從模型調用函數

替換此代碼

  let videoURL = course.introductionVideoURL

和

  guard let videoURL = URL(string: "https://something.mp4) else {
        return

從@ingconti answer 改進。 這對我有用。

 if let url = URL(string: "urUrlString"){
            let player = AVPlayer(url: url)
            let avController = AVPlayerViewController()
            avController.player = player
            // your desired frame
            avController.view.frame = self.view.frame
            self.view.addSubview(avController.view)
            self.addChild(avController)
            player.play()
        }
