Question

我是ios编程的新手，实际上我需要流视频网址，但我无法使用avplayer流式传输视频网址，但使用avplayer下载的文件我能够播放。实际问题是我的文件格式不同例如我的文件名就像这首歌.apa但它是song.mp4

代码：

let avplayerController = AVPlayerViewController()
var avPlayer:AVPlayer?

override func viewDidLoad()
{
    super.viewDidLoad()
    let movieUrl = URL.init(string: "http://techslides.com/demos/sample-videos/small.3gp")
    self.avPlayer = AVPlayer.init(url: movieUrl!)
    self.avplayerController.player = self.avPlayer
}

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

@IBAction func playVideo(_ sender: Any)
{
    self.present(self.avplayerController, animated: true) { 
     self.avplayerController.player?.play()
    }
}

在Swift 3中

import Foundation
import AVFoundation
import MediaPlayer
import AVKit


func play()
    {
        let player = AVPlayer(url: "Your Url")
        let playerViewController = AVPlayerViewController()
        playerViewController.player = player
        self.present(playerViewController, animated: true)
        {
            playerViewController.player!.play()
        }


    }

您无法使用AVPlayer或AVPlayerViewController播放此特定链接（http://techslides.com/demos/sample-videos/small.3gp），因为该文件采用AMR（自适应多速率，一种语音格式） - 自iOS 4.3起不受支持可以播放一些3gp文件，但只能播放Apple支持的视频和音频流。

import UIKit
import AVKit
import AVFoundation
import MediaPlayer
import MobileCoreServices

class VideoPlayerViewController: UIViewController,AVPlayerViewControllerDelegate {

    //MARK: - Outlet -
    @IBOutlet weak var viewVidioPlayer: UIView!
    //MARK: - Variable

    //MARK: - View Life Cycle -
    override func viewDidLoad() {
        super.viewDidLoad()        
    }
    //MARK: - Action -
    //for Playing Video
    @IBAction func btnvideoPlayClicked(_ sender: UIButton) {
         self.videoPlay()
    }

    func videoPlay()
    {
        let playerController = AVPlayerViewController()
        playerController.delegate = self

        let bundle = Bundle.main
        let moviePath: String? = "http://techslides.com/demos/sample-videos/small.3gp"
        let movieURL = URL(fileURLWithPath: moviePath!)

        let player = AVPlayer(url: movieURL)
        playerController.player = player
        self.addChildViewController(playerController)
        self.view.addSubview(playerController.view)
        playerController.view.frame = self.view.frame

        player.play()

    }
    //MARK: - other Function -

    func playerViewControllerWillStartPictureInPicture(_ playerViewController: AVPlayerViewController){
        print("playerViewControllerWillStartPictureInPicture")
    }

    func playerViewControllerDidStartPictureInPicture(_ playerViewController: AVPlayerViewController)
    {
        print("playerViewControllerDidStartPictureInPicture")

    }
    func playerViewController(_ playerViewController: AVPlayerViewController, failedToStartPictureInPictureWithError error: Error)
    {
        print("failedToStartPictureInPictureWithError")
    }
    func playerViewControllerWillStopPictureInPicture(_ playerViewController: AVPlayerViewController)
    {
        print("playerViewControllerWillStopPictureInPicture")
    }
    func playerViewControllerDidStopPictureInPicture(_ playerViewController: AVPlayerViewController)
    {
        print("playerViewControllerDidStopPictureInPicture")
    }
    func playerViewControllerShouldAutomaticallyDismissAtPictureInPictureStart(_ playerViewController: AVPlayerViewController) -> Bool
    {
        print("playerViewControllerShouldAutomaticallyDismissAtPictureInPictureStart")
        return true
    }
}

        super.viewDidLoad()
        let player = AVPlayer(url: URL(string: "http://techslides.com/demos/sample-videos/small.mp4")!)
        let controller = AVPlayerViewController()
        present(controller, animated: true) { _ in }
        controller.player = player
        addChildViewController(controller)
        view.addSubview(controller.view)
        controller.view.frame = CGRect(x: 50, y: 50, width: 300, height: 300)
        controller.player = player
        controller.showsPlaybackControls = true
        player.isClosedCaptionDisplayEnabled = false
        player.play()
    }

您可以使用YoutubePlayerView来播放YouTube视频，而对于其他格式，您可以使用UIWebView。为此，只需使用if-else块，

if movieUrl.contains("youtube.com/") {
    var videoId: String = extractYoutubeId(fromLink: movieUrl)
    youtubePlayerView.load(withVideoId: videoId)
} else {  
    webView = UIWebView(frame: CGRect(x: 0, y: 0, width: 288, height: 277))  
    webView.delegate = self
    webView.backgroundColor = UIColor.black  
    webView?.loadRequest(movieUrl)
}
