Seamless looping video issue

[pr0fess0r]

Hi
I'm trying to seamlessly loop a video in two ways - using the MediaPlayer framework (which fades in at the start and out at the end, which is no good - even if you load a still frame into the main view as a background, the MP seems to fade to and from black), or by animating the frames (which kills the phone if you use to many).

Framework example:

-(void)awakeFromNib {
	
	NSBundle *bundle = [NSBundle mainBundle];
	NSString *moviePath = [bundle pathForResource:@"MyMovie" ofType:@"m4v"];
	
	NSURL *movieURL;
	
	if (moviePath)
	{
		movieURL = [NSURL fileURLWithPath:moviePath];
	}
	
	if (movieURL != nil) {
		moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
		
		// Register to receive a notification when the movie has finished playing. 
		[[NSNotificationCenter defaultCenter] addObserver:self
												 selector:@selector(moviePlayBackDidFinish:) 
													 name:MPMoviePlayerPlaybackDidFinishNotification 
												   object:moviePlayer];
		
		moviePlayer.scalingMode = MPMovieScalingModeAspectFill; 
		moviePlayer.movieControlMode = MPMovieControlModeHidden;
		//moviePlayer.backgroundColor = [UIColor blackColor];
		
		[moviePlayer play];
	}
	
}

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

The animation example

- (void)viewDidLoad {
	
	// create the view that will execute our animation
	UIImageView* exampleView = [[UIImageView alloc] initWithFrame:self.view.frame];
	
	// load all the frames of our animation
	exampleView.animationImages = [NSArray arrayWithObjects:	
	[UIImage imageNamed:@"e001.jpg"],
								   
...

	[UIImage imageNamed:@"e451.jpg"],nil];
	
	// all frames will execute in 1.75 seconds
	exampleView.animationDuration = 15;
	// repeat the annimation forever
	exampleView.animationRepeatCount = 0;
	// start animating
	[exampleView startAnimating];
	// add the animation view to the main window 
	[self.view addSubview:exampleView];
	[exampleView release]; 
	
}

Can anyone suggest a better way to seamlessly loop a 15 second video?

Cheers

avoid imageNamed, try imageWithContentsOfFile instead

Thanks for that - I decided to go with the MediaPlayer method because you can set the background color to be clear, which means the still frame shows through while the video fades in/out. Oddly if I have my phone plugged in to XCode and Run the app it works great, but if I run the app on the phone with it untethered I get a moment of black between each run of the video (this is my first iPhone app by the way) - why would that be? Do I need to put a release version on my phone to make it play smoothly?

i've tried the same thing - but my video fickers when I re-play it... It seem the background is showing every several ms. - the problem doubles every time i replay the movie.

does anyone have a solution for this ?

Hey, I know it's been a long time, but did you ever figure this out?? I desperately, need to do the same thing. I have two different clips. Once one finished, the other plays, but there is a clear pause between the two.

PLZ help..did any one got it????

myMoviePlayer.repeatMode = MPMovieRepeatModeOne; /// LOOPS MOVIE FOREVER

[charlesmwray]

To get it to loop forever I used the following code:

playercontroller.moviePlayer.repeatMode = MPMovieRepeatModeOne;

Where

playercontroller

is the name of my MPMoviePlayerViewController. The rest is just part of the class.
