Question

我正在使用iphone中的视频应用。当用户点击按钮时，它将进入第二个视图，然后从那里我正在播放来自网址的视频。

但是当用户从该视图返回并且agin转到该视频没有播放时。

连续显示以下2行

     [MPAVController] Autoplay: Likely to keep up or full buffer: 0
     [MPAVController] Autoplay: Skipping autoplay, not enough buffered to keep up.

这是我的代码

  - (void)viewDidLoad
  {
[super viewDidLoad];


 self.moviePlayerController = [[MPMoviePlayerController alloc] init];
[self.moviePlayerController prepareToPlay];
self.moviePlayerController.shouldAutoplay = YES;
[[self.moviePlayerController view] setFrame:CGRectMake(-30, 72, 360,140)];


[[self view] addSubview: [self.moviePlayerController view]];


  NSString *strng = [NSString stringWithFormat:@"http://quickemee_videos.s3.amazonaws.com/videoStream_1352395870143_616.mp4"];

NSLog(@"strng %@",strng);
NSURL * adurl = [NSURL URLWithString:strng];

 [self playVideo:adurl];

 }

。。。

 -(IBAction)back:(id)sender{


 [moviePlayerController stop];
[self.navigationController popViewControllerAnimated:YES];

   }

Answer 1

使用此代码

    NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"video_name" ofType:@"m4v"]];

    moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];

    [moviePlayer prepareToPlay];
    moviePlayer.view.frame = self.view.bounds;
    [self.view addSubview:moviePlayer.view];
    [moviePlayer play];
    [moviePlayer setFullscreen:FALSE];
// if you want no control.
    [moviePlayer setControlStyle:MPMovieControlStyleNone];

Answer 2

首先尝试拨打[self prepareToPlay]。

Apple说：

如果电话播放器在您拨打电话时尚未准备好播放 play方法，该方法自动调用此方法。但是，要最小化播放延迟，请在调用播放前调用此方法。

确保该文件可用。我无法在浏览器中访问它。

Answer 3

viewDidLoad只被调用一次。因此，当您弹出viewController然后返回它时，不会再次调用viewDidLoad。因此，请尝试在self.moviePlayerController = [[MPMoviePlayerController alloc] init];

中实施- (void)viewWillAppear:(BOOL)animated

MPMoviePlayer无法正常工作
