如何使用 AVPlayer 播放视频？

Question

Apple Swift 版本 3.0.2 (swiftlang-800.0.63 clang-800.0.42.1)

我想使用 AVPlayer 播放来自互联网的视频。 但是，在下面源列表的 AVPlayer.swift 中发生了错误“super.init(frame:frame)”。

线程 1：EXC_BAD_ACCESS（代码=2，地址=0x16fc07fe0）

如何使用 AVPlayer 播放视频？ 如果除了错误点之外还有错误点，也请告诉我。

AVPlayerView.swift

import Foundation
import UIKit

final class AVPlayerView : UIView {
    required init(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)!
    }
    override init(frame: CGRect) {
        super.init(frame: frame)
    }
    override public class var layerClass: Swift.AnyClass {
        get {
            return AVPlayerView.self
        }
    }

}

ViewController.swift

import UIKit
import AVFoundation
import CoreMedia

class ViewController: UIViewController {
    var playerItem : AVPlayerItem!
    var videoPlayer : AVPlayer!

    override func viewDidLoad() {
        super.viewDidLoad()
        let url:NSURL = NSURL(string: "https://aaa.com/test.m3u8")!
        let avAsset = AVURLAsset(url: url as URL, options: nil)

        playerItem = AVPlayerItem(asset: avAsset)

        videoPlayer = AVPlayer(playerItem: playerItem)

        print(self.view.bounds)
        let videoPlayerView = AVPlayerView(frame: self.view.bounds)

        let layer = videoPlayerView.layer as! AVPlayerLayer
        layer.videoGravity = AVLayerVideoGravityResizeAspect
        layer.player = videoPlayer

        self.view.layer.addSublayer(layer)
        videoPlayer.play()
    }

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

Answer 1

这是播放视频的代码：

let videoURL = NSURL(string: "PUT_YOUR_PROPER_URL")
let playerAV = AVPlayer(url: videoURL! as URL)
let playerLayerAV = AVPlayerLayer(player: playerAV)
playerLayerAV.frame = self.view.bounds
self.view.layer.addSublayer(playerLayerAV)
playerAV.play()

AVPlayer 支持以下扩展：

public.mpeg
public.mpeg-2-video
public.avi
public.aifc-audio
public.aac-audio
public.mpeg-4
public.au-audio
public.aiff-audio
public.mp2
public.3gpp2
public.ac3-audio
public.mp3
public.mpeg-2-transport-stream
public.3gpp
public.mpeg-4-audio

确保您可以在 AVPlayer 中使用支持的视频。
