Rotating a video with iPhone Simulator

Hi.

I used this youtube video (http://www.youtube.com/watch?v=j6922mZ0WUU) to make an application where an iPhone shows a video.
However, starting at 4:25, I used another code (the code of the video does not work with the current sdk).

Here's the code that i used:

- (IBAction)playMovie {
	
	NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"MOVIE001" ofType:@"mov"]];  
	MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];  
	
	// Register to receive a notification when the movie has finished playing.  
	[[NSNotificationCenter defaultCenter] addObserver:self  
											 selector:@selector(moviePlayBackDidFinish:)  
												 name:MPMoviePlayerPlaybackDidFinishNotification  
											   object:moviePlayer];  
	
	if ([moviePlayer respondsToSelector:@selector(setFullscreen:animated:)]) {  
		// Use the new 3.2 style API  
		moviePlayer.controlStyle = MPMovieControlStyleNone;  
		moviePlayer.shouldAutoplay = YES;  
		[self.view addSubview:moviePlayer.view];  
		[moviePlayer setFullscreen:YES animated:YES];  
	} else {  
		// Use the old 2.0 style API  
		moviePlayer.movieControlMode = MPMovieControlModeHidden;  
		[moviePlayer play];  
	}  
	 

}

Open in new window


The application is running ok but when I turn the iPhone simulator the video doesn't rotate.

What changes should I do in my code?

Thanks and sorry for my bad english!

Just found a nice article:
Play iPhone Movies in Portrait Mode with MPMoviePlayerController using Public API’s
http://iphonedevelopertips.com/video/play-movies-in-portrait-mode-with-mpmovieplayercontroller-using-public-apis.html
You can download the source code - in the bottom of the article. It looks very nice.

The answer on your question is here:
http://stackoverflow.com/questions/3019200/how-to-rotate-an-mpmovieplayercontroller
http://stackoverflow.com/questions/2852872/mpmovieplayercontroller-fullscreen-quirk-in-ipad/3026039#3026039

You will see - people proposes to make new class derived from the movie controller and add method:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
    return UIInterfaceOrientationIsLandscape(toInterfaceOrientation);
}

Then use this class instead of the  MPMoviePlayerController.

BTW, please pay attention on movieFinishedCallback - that's answer on your question how to know when the show finished (if you are still looking for it).

MPMoviePlayerViewController - that's the point. It's a night here already. Maybe because of that, I missed that before.
Here you will find full program: http://www.devx.com/wireless/Article/44642/1954
It has movieFinishedCallback (you asked in your first question about the subject).
It shows how to switch to the portrait mode:
[player setOrientation:UIDeviceOrientationPortrait animated:NO];

This app, when you will have it working, will be a base for other improvements.
Sorry, I just started from the code you proposed - MoviePlayer sample.

all right but i follow the steps of this link http://www.devx.com/wireless/Article/44642/1954
but when i debug it, i can hear the sound but i cant see the video images.
i believe that is a sdk problem, because he made it with a older version than the mine.

Because this part changed in iOS 4. Compare with other examples you have and see them working.
