如何在 UIView swift 中播放视频？

Question

我有一个视频，我想从服务器下载并以固定视图流式传输。 我在故事板中设置了一个具有固定约束的 UIView，这是我在代码中所做的：

@IBOutlet weak var videoView: UIView!
var player: AVPlayer!
var avpController = AVPlayerViewController()

在我的

viewDidLoad

中我做到了：

let url = URL(string:myURL)
player = AVPlayer(url: url!)

avpController.player = player
avpController.videoGravity = AVLayerVideoGravity.resizeAspect.rawValue
self.addChildViewController(avpController)
avpController.view.frame = videoView.frame
self.containerView.addSubview(avpController.view)
videoView.layer.masksToBounds = true

我的问题是我的视频不是我设置的大小

videoView

并且在每台设备上我的视频都是不同的大小。在某些设备中，视频高度大于我设置的高度，它覆盖了我在

videoView

下面的项目。如何以正确的方式在视图中播放视频？

Answer 1

如果要使用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()
}

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()

Answer 2

在故事板中使用固定约束将视频添加到 UIView 的唯一方法是：

let url = URL(string:myURL)

player = AVPlayer(url: url!)

avpController.player = player

avpController.view.frame.size.height = videoView.frame.size.height

avpController.view.frame.size.width = videoView.frame.size.width

self.videoView.addSubview(avpController.view)

我希望其他人可以使用这个！ :)

您可以尝试在

AVPlayerLayer

中使用

AVPlayer

。

      let player = AVPlayer(url: video) // your video url
      let playerLayer = AVPlayerLayer(player: player)
      playerLayer.frame = videoView.bounds
      videoView.layer.addSublayer(playerLayer)
      player.play()

这是在 uiview 中添加和删除播放器的方法。

var player: AVPlayer?
var playerController: AVPlayerViewController?
func removePlayer() {
    player?.pause()
    player = nil
    playerController?.player?.pause()
    playerController?.player = nil
    if let view = playerController?.view {
        videoView.willRemoveSubview(view)
    }
    playerController?.view.removeFromSuperview()
    playerController = nil
}

func setVideo(url: URL) {
    removePlayer()
    player = AVPlayer(url: url)
    playerController = AVPlayerViewController()
    playerController?.player = player
    self.videoView.addSubview((playerController?.view)!)
    playerController?.view.frame = CGRect(x: 0, y: 0, width: self.videoView.bounds.width, height: self.videoView.bounds.height)
   // player.play()
}

import AVKit
import AVFoundation
import UIKit
class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

    }

    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        let player = AVPlayer(url: URL(fileURLWithPath: Bundle.main.path(forResource: "shiv", ofType: "mp4")!))
    
        let vc = AVPlayerViewController()
        vc.player = player
        present(vc, animated: true)
    }
}
