如何播放本地视频文件？

Question

我已经使用屏幕（桌面）捕获软件创建了 .mov 视频文件，我希望该视频在 UIWebview 的应用程序中播放。有没有办法播放该视频或任何其他方式，以便我可以为我的本地视频创建 URL ???

现在我使用默认视频链接在 UIWebview 中播放视频。

这是代码：

- (void)applicationDidBecomeActive:(UIApplication *)application 
{

    self.viewVideoDisplay.frame = CGRectMake(0, 0, 1024, 1024);
    [self.window addSubview:self.viewVideoDisplay];
    [self.window bringSubviewToFront:self.viewVideoDisplay];
    NSString *urlAddress = @"https://response.questback.com/pricewaterhousecoopersas/zit1rutygm/";
    //Create a URL object.
    NSURL *url = [NSURL URLWithString:urlAddress];            
    //URL Requst Object
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];            
    //Load the request in the UIWebView.
    [self.webViewVideo loadRequest:requestObj];

    IsLoadingSelf = YES;
}

但是我没有我想播放的视频的网址..

请帮忙！！

编辑：

MPMoviePlayerController

现已弃用。所以我用了

AVPlayerViewController

。并编写了以下代码：

    NSURL *videoURL = [NSURL fileURLWithPath:filePath];
//filePath may be from the Bundle or from the Saved file Directory, it is just the path for the video
    AVPlayer *player = [AVPlayer playerWithURL:videoURL];
    AVPlayerViewController *playerViewController = [AVPlayerViewController new];
    playerViewController.player = player;
    //[playerViewController.player play];//Used to Play On start
    [self presentViewController:playerViewController animated:YES completion:nil];

请不要忘记导入以下框架：

#import <AVFoundation/AVFoundation.h>
#import <AVKit/AVKit.h>

您可以使用

MPMoviePlayerController

播放本地文件。

1. 添加

Mediaplayer

框架并在 viewController 中执行

#import <MediaPlayer/MediaPlayer.h>

。

2. 将您在桌面上创建的视频文件拖放到 xcode 中。

3.获取本地视频的路径。

NSString*thePath=[[NSBundle mainBundle] pathForResource:@"yourVideo" ofType:@"MOV"];
NSURL*theurl=[NSURL fileURLWithPath:thePath];

4. 使用您的路径初始化 moviePlayer。

self.moviePlayer=[[MPMoviePlayerController alloc] initWithContentURL:theurl];
[self.moviePlayer.view setFrame:CGRectMake(40, 197, 240, 160)];
[self.moviePlayer prepareToPlay];
[self.moviePlayer setShouldAutoplay:NO]; // And other options you can look through the documentation.
[self.view addSubview:self.moviePlayer.view];

5. 控制播放后要执行的操作：

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playBackFinished:) name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayer]; 
//playBackFinished will be your own method.

编辑 2：要处理

AVPlayerViewController

而不是

MPMoviePlayerController

的完成，请使用以下...

AVPlayerItem *playerItem = player.currentItem;

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playBackFinished:) name:AVPlayerItemDidPlayToEndTimeNotification object:playerItem];

在此示例中，我在完成后忽略

AVPlayerViewController

：

-(void)playBackFinished:(NSNotification *) notification {
    // Will be called when AVPlayer finishes playing playerItem

    [playerViewController dismissViewControllerAnimated:false completion:nil];
}

只需将您的网址替换为以下代码即可

NSString *filepath   =   [[NSBundle mainBundle] pathForResource:@"videoFileName" ofType:@"m4v"];  

NSURL *fileURL    =   [NSURL fileURLWithPath:filepath];

上述解决方案解释了如何使用 NSBundle 播放 Xcode 中存在的视频。我的答案将对那些正在寻找从设备动态选择视频并播放的人有所帮助。

class ViewController: UIViewController,UIImagePickerControllerDelegate, UINavigationControllerDelegate

import AVFoundation
import AVKit
import MobileCoreServices 

（不要忘记在构建阶段添加 MobileCoreServicesFramework）

设置视频属性。例如

@IBAction func buttonClick(sender: AnyObject)
{
    imagePicker.delegate = self
    imagePicker.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
    imagePicker.mediaTypes = [kUTTypeMovie as String]
    imagePicker.allowsEditing = true
    self.presentViewController(imagePicker, animated: true,
        completion: nil)
}

然后实现UIImagePickerControllerDelegate函数

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject])
    {
        var filename = ""
        let mediaType = info[UIImagePickerControllerMediaType] as! NSString
        if mediaType.isEqualToString(kUTTypeMovie as String)
        {
            let url = info[UIImagePickerControllerMediaURL] as! NSURL
            filename = url.pathComponents!.last!
        }
        self.dismissViewControllerAnimated(true, completion: nil)
        self.playVideo(filename)
    }

并使用上面的文件名，您可以播放视频:)

    func playVideo(fileName : String)
    {
        let filePath = NSURL(fileURLWithPath: NSTemporaryDirectory()).URLByAppendingPathComponent(fileName)
        let player = AVPlayer(URL: filePath)
        let playerViewController = AVPlayerViewController()
        playerViewController.player = player
        self.presentViewController(playerViewController, animated: true)
        {
            player.play()
        }
    }

这里有一些很好的播放视频的库：

• 基于AVPlaer
• 基于 AVPlaer + VLC 套件
