问题采摘视频和玩它

我正在试图从lib中播放视频，但我不能弄清楚做什么我错了我已经尝试了许多东西，它没有显示任何类型的错误我的代码如下问题采摘视频和玩它

- (void) imagePickerController: (UIImagePickerController *) picker 
didFinishPickingMediaWithInfo: (NSDictionary *) info { 

    NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType]; 

    NSURL *url = [[NSURL alloc]initWithString:mediaType]; 

    NSLog(@"%@",url); 

    [self dismissModalViewControllerAnimated:NO]; 


    /* Create a new movie player object. */ 
    MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:url]; 

    if (player) 
    { 
       /* Specify the URL that points to the movie file. */ 
     [player setContentURL:url]; 





     /* Add a background view as a subview to hide our other view controls 
     underneath during movie playback. */ 


     CGRect viewInsetRect = CGRectInset ([self.view bounds], 
              kMovieViewOffsetX, 
              kMovieViewOffsetY); 
     /* Inset the movie frame in the parent view frame. */ 
     [[player view] setFrame:viewInsetRect]; 

     [player view].backgroundColor = [UIColor lightGrayColor]; 

     /* To present a movie in your application, incorporate the view contained 
     in a movie player’s view property into your application’s view hierarchy. 
     Be sure to size the frame correctly. */ 
     [self.view addSubview: [player view]]; 


     [player setCurrentPlaybackRate:0.5]; 
     [player play]; 
    } 







     // Register for the playback finished notification 
     [[NSNotificationCenter defaultCenter] 
     addObserver: self 
     selector: @selector(myMovieFinishedCallback:) 
     name: MPMoviePlayerPlaybackDidFinishNotification 
     object: player]; 



} 



// When the movie is done, release the controller. 
-(void) myMovieFinishedCallback: (NSNotification*) aNotification 
{ 
    MPMoviePlayerController *playerr = [aNotification object]; 
    [[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification 
                object:playerr]; 
    [playerr stop]; 
    [self.view removeFromSuperview]; 
    [playerr autorelease]; 
}

发生了什么是第一presetModelViewController越来越显示，然后我可以显示在我的lib中的视频，我可以选择其中之一，但是当我选择视频，然后它显示我的灰色视图，没有别的，我的视频没有播放。

如果你可以在我的代码中发现任何错误，并可以帮助我，那么这将是很大的帮助。

     NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType]; 


     [self dismissModalViewControllerAnimated:NO]; 

     // Handle a movie capture 
     if (CFStringCompare ((__bridge_retained CFStringRef)mediaType, kUTTypeMovie, 0) 
      == kCFCompareEqualTo) { 

      NSString *moviePath = [[info objectForKey: 
            UIImagePickerControllerMediaURL] path];
