Approval error: player has invalid activation state (1)

I play video (m4v) in the iPad app on one page, then it goes to another view controller that plays another video. It works fine, but when the second video ends, it gives an approval message.

Error:

Does anyone know why I am getting this error?

I found a problem. The first video did not remove the MPMoviePlayerPlaybackDidFinishNotification notification, and therefore the second video was downloaded several times.

If you have multiple MoviePlayers, make sure that you only register with this exact player for notifications. eg:.

 NSNotificationCenter *center = [NSNotificationCenter defaultCenter]; [center addObserver:self selector:@selector(moviePlaybackStateChanged:) name:MPMoviePlayerPlaybackDidFinishNotification object:self.movieController];

This ensures that you only receive notifications from the right player.
This fixed it for me, at least.

Just stop the player before initializing it again.

[Stop Player],
