如何在ios swift中播放视频答案

【问题标题】：How to play video in ios swift如何在ios swift中播放视频

【问题描述】：

我是 ios 编程新手，实际上我需要流式传输视频 URL，但我无法使用 avplayer 流式传输视频 URL，但使用 avplayer 下载的文件我可以播放。实际问题是我的文件格式不同例如我的文件名就像这 song.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()
    }
}

【问题讨论】：

AVPlayer 无法流式传输 Youtube 视频，请参阅此答案 stackoverflow.com/a/34709948/1518174
在 youtube 中是基于在 iframe 中工作的，你不能在 avplayer 中播放。使用 webview 或 youtubeplayer
不仅 youtube 视频其他视频链接我也无法播放，我更改了链接
你可以举一些例子，检查你的应用程序传输安全是否被阻止

【解决方案1】：

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，但只有那些具有 Apple 支持的视频和音频流的文件。

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()
        }


    }

在 Swift 3 中，尝试使用此代码在项目中播放视频

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
    }
}

我希望它对你有用，谢谢你

我可以播放的本地文件，但我的流媒体网址有不同的扩展名，例如 192.179.10.11/content/song1.apa 但实际文件是 song1.mp4

【解决方案4】：

这里有一个流式视频的例子..

override func viewDidLoad() {
        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()
    }

我的流媒体视频 url 链接扩展名不同，例如 song1.apa 但实际格式是 song1.mp4
song1.apa ??从未听说过 .apa 扩展名
song1.app 但我的文件只有在我将该链接提供给正在运行的 android 播放器时才是 mp4
文件格式是否与ios中的实际mime类型匹配有任何限制
如果你的文件是 mp4 为什么 url 返回 song.apa

【解决方案5】：

您可以使用 YoutubePlayerView 播放 youtube 视频，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)
}

对于 Swift 3，从 URL 播放视频

//AVPlayerViewControllerDelegate // example : class TestAudioVideoVC: UIViewController,AVPlayerViewControllerDelegate

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

        let videoURL = NSURL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")

        let player = AVPlayer(url: videoURL! as URL)
        playerController.player = player
        self.addChildViewController(playerController)
        self.view.addSubview(playerController.view)
        playerController.view.frame = CGRect(x: 0, y: 64, width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.height - 64)
        playerController.showsPlaybackControls = true
        player.play()
    }

//MARK: - AVPlayerViewController Delegate -

    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
    }

在 swift 5 中播放视频

类视图控制器：UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()
}

@IBAction func playVideoUsingURL(_ sender: Any) {
    playGlobalVideo()
}

@IBAction func playVideoFromLocalDrive(_ sender: Any) {
    playLocalVideo()
}

func playGlobalVideo() {
    guard let videoURL = URL(string: "http://static.videokart.ir/clip/100/480.mp4") else {
        return
    }
    let player = AVPlayer(url: videoURL)
    let vc = AVPlayerViewController()
    vc.player = player
    present(vc, animated: true) {
        player.play()
    }
}

func playLocalVideo() {
    guard let videoPath = Bundle.main.path(forResource: "movie", ofType: "mov") else {
        return
    }
    let player = AVPlayer(url: URL.init(fileURLWithPath: videoPath))
    let playCtr = AVPlayerViewController()
    playCtr.player = player
    present(playCtr, animated: true) {
        player.play()
    }
}

}
