MPMoviePlayerController only playing audio

[kieran12]

As the title says my MPMoviePlayerController should display on the button press but instead only the audio plays. I know it's not a problem with my video file as I have tried several including a sample video of the .mp4 format from apple.

Here is my code:

-(IBAction)playVideo:(id)sender {
	NSBundle *bundle = [NSBundle mainBundle];
	NSString *moviePath = [bundle pathForResource:@"movie" ofType:@"mp4"];
	
	NSURL *movieURL;
	
	if (moviePath)
	{
		movieURL = [NSURL fileURLWithPath:moviePath];
	}
	
	if (movieURL != nil) {
		moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
		
		[[NSNotificationCenter defaultCenter] addObserver:self
												 selector:@selector(moviePlayBackDidFinish:) 
													 name:MPMoviePlayerPlaybackDidFinishNotification 
												   object:moviePlayer];
		moviePlayer.fullscreen = YES;
		moviePlayer.scalingMode = MPMovieScalingModeAspectFill; 
		
		[moviePlayer play]; 
		
	}
	
}

-(void)moviePlayBackDidFinish: (NSNotification*)notification
{
	moviePlayer = [notification object];
	[moviePlayer stop];
}

Can you see any issues? I'm using iOS4.0 and SDK 4.0.

Thanks

If you want it to be this simple on iOS 4.0, look up MPMoviePlayerViewController.

Thanks, didn't realise they changed to a new class.

I had the exact same problem. Except, when I tried to use the MPMoviePlayerViewController as I've seen in different examples out there I get an error:

MPMoviePlayerViewController undeclared (first use in function)

from this line of code:

MPMoviePlayerViewController *playerViewController =
[[MPMoviePlayerViewController alloc]
initWithContentURL:[NSURL fileURLWithPath:url]];

I have SDK 3.2, and I've included the MediaPlayer.h file. I'm not sure what I'm doing wrong. Any ideas?

If you look at the docs for MPMoviePlayerViewController, you'll see you also have to include MPMoviePlayerViewController.h

I had tried the include earlier but was getting an error even with that. I went and started digging around in the framework folder and realized that file wasn't even there! I had the iPhone 3.2 SDK, which should include it. I'm not sure what happened there. I reinstalled xcode and deleted / relinked that framework and now I can at least build it....doesn't work yet...but that is progress.

Thanks!
