Question

我正在尝试从远程网址播放视频。但它没有用。我的代码是：

- (void)viewDidLoad {
    [super viewDidLoad];

    NSLog(@"start playing");

    NSURL *nsURL= [[NSURL alloc]initWithString:@"http://my_server_path:8080/content-service/v1/video/12/RGl1Nm1ib1VLMitFUmM5bEZzYVpxVGllM2RrWUw3Y09yMzdVZ0pzYlEvYjNaYUI5bEQvZERhTUhNTjBOaW5lY1hqYlZSRUM5anAvL3FsUTA2NzEwN2NMM2dnUnkxR0s4QUVyMnV2MlBLMjA9?thumb=false"];

    videoPlayer =  [[MPMoviePlayerController alloc]
                    initWithContentURL:nsURL];

    [videoPlayer.view setFrame:CGRectMake(0, 0,self.view.frame.size.width, self.view.frame.size.height)];
    videoPlayer.controlStyle = MPMovieControlStyleDefault;
    videoPlayer.movieSourceType = MPMovieSourceTypeStreaming;//MPMovieSourceTypeFile/MPMovieSourceTypeUnknown ;
    [self.view addSubview:videoPlayer.view];
    [videoPlayer prepareToPlay];
    [videoPlayer play];

    [[NSNotificationCenter defaultCenter] addObserver:self
                                                      selector:@selector(moviePlayBackDidFinish:)
                                                          name:MPMoviePlayerPlaybackDidFinishNotification
                                                        object:videoPlayer];

    videoPlayer.shouldAutoplay = YES;
}

- (void) moviePlayBackDidFinish:(NSNotification*)notification {

    NSError *error = [[notification userInfo] objectForKey:@"error"];
    if (error) {
        NSLog(@"Did finish with error: %@", error);
    }
}

我收到此消息

完成错误：错误Domain = MediaPlayerErrorDomain Code = -11850“Operation Stopped”UserInfo = 0x15e77b20 {NSLocalizedDescription =操作已停止}

当我在浏览器中复制/粘贴我的视频URL时，它会成功下载（甚至不是浏览器中的缓冲区），完成下载后，它在笔记本电脑中播放正常。我很沮丧，请帮助，任何建议都会很棒，提前致谢

Answer 1

如果视频未在设备上播放，则您的HTTP服务器不支持字节范围请求。

托管iOS媒体文件的HTTP服务器必须支持字节范围请求，iOS用于在媒体播放中执行随机访问。（字节范围支持也称为内容范围或部分范围支持。）大多数（但不是全部）HTTP 1.1服务器已经支持字节范围请求。

使用此代码：

其中fileURL是服务器上视频的网址

    MPMoviePlayerViewController* tmpMoviePlayViewController=[[MPMoviePlayerViewController alloc] initWithContentURL:fileURL];

    if (tmpMoviePlayViewController) {
        tmpMoviePlayViewController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
        [self presentViewController:tmpMoviePlayViewController animated:YES completion:nil];
        [tmpMoviePlayViewController.moviePlayer prepareToPlay];
//        tmpMoviePlayViewController.moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
        tmpMoviePlayViewController.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
        [tmpMoviePlayViewController.moviePlayer play];

    }

Answer 3

使用fileUrl

替换此代码中的网址

    MPMoviePlayerViewController *mpvc = [[MPMoviePlayerViewController alloc] init];
    mpvc.moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
    [mpvc.moviePlayer setContentURL:fileURL];
    [self presentMoviePlayerViewControllerAnimated:mpvc];

iOS- MPMoviePlayerController可以播放来自远程URL的视频
