iphone - MPMoviePlayerViewController Generating lots of errors

Question

I am having issues to get MPMoviePlayerViewController to work. I have a new project that after viewDidLoad I try to play the movie in a moviePlayerViewController as below. I get the movie to play put I get lots and lots of error messages as below. Can someone explain what I am doing wrong to get these errors

- (void)viewDidLoad
{
    [super viewDidLoad];
    [ self play ];
}

- (void) play {
    NSURL *filmURL = [ NSURL URLWithString:@"http://www.ud-ltd.com/ipmt/Film16.mp4" ];
    self.mvc = [[MPMoviePlayerViewController alloc] initWithContentURL:filmURL ];
    [ self presentMoviePlayerViewControllerAnimated:self.mvc ];
    [ self.view addSubview:self.mvc.view ];
    [ self.mvc.moviePlayer play];
}

The error messages

Answer 1

I am also using MPMoviePlayerViewController to play live video in one of my App & I also

getting these errors but besides these errors my video is playing fine with this player.

I think there is no solution for it. If your video is working fine then ignore these warnings

or errors.
