本地视频文件循环 tvOS

Question

我正在尝试使用 Swift 为 tvOS 在 Xcode7 中播放一个简单的本地剪辑。我想要的只是让视频在视图和循环中加载全屏。我看到的每个教程都有旧的 MPMoviePlayerController 或从 URL 加载。在 tvOS 上执行此操作的最佳方法是什么？

更新 2：这使视频循环播放，但中间有一个停顿。现在研究它，看看如何无缝地做到这一点。

import UIKit
import AVKit
import AVFoundation



class ViewController: UIViewController {



var videoPlayer: AVPlayer!
var playerLayer: AVPlayerLayer?



override func viewDidLoad() {
    super.viewDidLoad()

    let path = NSBundle.mainBundle().pathForResource("video", ofType:"mp4")
    let url = NSURL(fileURLWithPath: path!)
    let playerItem = AVPlayerItem(URL: url)

    self.videoPlayer = AVPlayer(playerItem: playerItem)
    self.playerLayer = AVPlayerLayer(player: self.videoPlayer)
    self.playerLayer!.frame = self.view.frame
    self.videoPlayer!.play()

    self.view.layer.addSublayer(self.playerLayer!)






    NSNotificationCenter.defaultCenter().addObserver(self, selector: Selector("playerDidReachEnd:"), name: AVPlayerItemDidPlayToEndTimeNotification, object:nil)
    }






    func playerDidReachEnd(notification: NSNotification) {
        self.videoPlayer.seekToTime(kCMTimeZero)
        self.videoPlayer.play()
    }




}

Answer 1

假设您的文件名为 video.m4v 并存储在设备本地（不要忘记在构建阶段将其添加到复制捆绑资源）。创建一个存储的属性以便您可以访问 AVPlayer-instance:

var videoPlayer: AVPlayer?

设置视频播放器并将 AVPlayerLayer 添加到您的视图层次结构。

if let path = NSBundle.mainBundle().pathForResource("video", ofType:"m4v") {
    let url = NSURL(fileURLWithPath: path)
    let playerItem = AVPlayerItem(URL: url)

    self.videoPlayer = AVPlayer(playerItem: playerItem)
    self.playerLayer = AVPlayerLayer(player: self.videoPlayer)
    self.playerLayer!.frame = self.view.frame

    self.view.layer.addSublayer(self.playerLayer!)
    NSNotificationCenter.defaultCenter().addObserver(self, selector: Selector("playerDidReachEnd:"), name: AVPlayerItemDidPlayToEndTimeNotification, object:nil)
}

您现在已经订阅了我在该视频结束时发送的通知。实施处理程序并告诉播放器重播视频。

func playerDidReachEnd(notification: NSNotification) {
    self.videoPlayer.seekToTime(kCMTimeZero)
    self.videoPlayer.play()
}
