I'm running the following code. The video plays fine but after it finishes it just goes to a black srcreen, my original view never comes back. When I tap on the black screen i just see the message "loading....." Can someone please explain what I'm doing wrong. Thanks

{
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]
pathForResource:#"IMG_0973" ofType:#"MOV"]];
moviePlayer=[[MPMoviePlayerController alloc] initWithContentURL:url];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayer];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayBackDonePressed:) name:MPMoviePlayerDidExitFullscreenNotification object:moviePlayer];
moviePlayer.controlStyle=MPMovieControlStyleDefault;
//moviePlayer.shouldAutoplay=NO;
[moviePlayer play];
[self.view addSubview:moviePlayer.view];
[moviePlayer setFullscreen:YES animated:YES];
}
}
- (void) moviePlayBackDonePressed:(NSNotification*)notification
{
[moviePlayer stop];
[[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerDidExitFullscreenNotification object:moviePlayer];
if ([moviePlayer respondsToSelector:#selector(setFullscreen:animated:)])
{
[moviePlayer.view removeFromSuperview];
}
moviePlayer=nil;
}

{
[moviePlayer stop];

[moviePlayer.view removeFromSuperview];
}
}

Answer 1

Add this notification Method
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePreloadDidFinish:) name:MPMoviePlayerLoadStateDidChangeNotification
object:player];
This method is called after your movie is loaded and in this method you add your moviePlayer view.
-(void)moviePreloadDidFinish:(NSNotification*)notification
{
moviePlayer.controlStyle=MPMovieControlStyleDefault;
[self.view addSubview:moviePlayer.view];
[moviePlayer play];
[moviePlayer setFullscreen:YES animated:YES];
}

Answer 2

In your video IBAction, you need to add the subview before you tell it to play. Switch the lines [moviePlayer play] and [self.view addSubview:moviePlayer.view]. Let us know it it works! Actually you may need to place moviePlayer play even after the full screen line.

i think this will help you .....
-(void)playVideo
{
NSString *contentURL = [[NSBundle mainBundle] pathForResource:#"xyz" ofType:#"mp4"];
MPMoviePlayerViewController *moviePlayerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL fileURLWithPath:contentURL]];
if (moviePlayerViewController)
{
[moviePlayerViewController.moviePlayer setMovieSourceType:MPMovieSourceTypeFile];
[moviePlayerViewController.moviePlayer setFullscreen:YES];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(MovieFinished:) name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayerViewController.moviePlayer];
[moviePlayerViewController.moviePlayer play];
[navi presentModalViewController:moviePlayerViewController animated:NO];
[moviePlayerViewController release];
moviePlayerViewController = nil;
}
}
-(void)MovieFinished:(NSNotification *)notification
{
MPMoviePlayerController *player = (MPMoviePlayerController *)notification.object;
[player stop];
[[NSNotificationCenter defaultCenter] removeObserver:self];
//do rest of the stuff
}
