Smooth video looping in iOS
Solution 1
I can concur @SamBrodkin's findings.
[[NSNotificationCenter defaultCenter]
addObserver: self
selector: @selector(myMovieFinishedCallback:)
name: MPMoviePlayerPlaybackStateDidChangeNotification
object: m_player];
and
-(void) myMovieFinishedCallback: (NSNotification*) aNotification
{
NSLog( @"myMovieFinishedCallback: %@", aNotification );
MPMoviePlayerController *movieController = aNotification.object;
NSLog( @"player.playbackState = %d", movieController.playbackState );
}
fixed the non-looping issue on iOS 5 for me too.
Solution 2
I just got this working on my iPad 3 running iOS 5.1.1, base SDK iOS 5.1
When setting up the movie player, set the repeat mode to MPMovieRepeatModeNone then add the notification
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(moviePlayerDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:self.moviePlayer];
Then set up your selector to filter when the movie finishes playing
- (void)moviePlayerDidFinish:(NSNotification *)note {
if (note.object == self.moviePlayer) {
NSInteger reason = [[note.userInfo objectForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey] integerValue];
if (reason == MPMovieFinishReasonPlaybackEnded) {
[self.moviePlayer play];
}
}
}
Apple made some large changes to how the MPMoviePlayerController handles loading movie files when they changed from iOS 4 to iOS 5, so I do not know if this method will work when they release iOS 6

To see an example that shows seamless looping of a background video (from an animated GIF) and switching between a pair of foreground character animations (with alpha channel), have a look at seamless-video-looping-on-ios. I tried to use AVPlayer in the past and had to give up on AVPlayer related solutions as they did not work well enough. See this SO question also iphone-smooth-transition-from-one-video-to-another.

Can anyone suggest a method by which you can achieve a completely smooth and seamless looping of a video clip in iOS? I have tried two methods, both of which produce a small pause when the video loops
1) AVPlayerLayer with the playerItemDidReachEnd notification setting off seekToTime:kCMTimeZero
I prefer to use an AVPlayerLayer (for other reasons), but this method produces a noticeable pause of around a second between loops.
2) MPMoviePlayerController with setRepeatMode:MPMovieRepeatModeOne
This results in a smaller pause, but it is still not perfect.
I'm not sure where to go from here. Can anyone suggest a soultion?

MoDJ over 8 yearsLink broken, also suggested solution does not work for truly seamless looping.
