Playing two videos after another causes short black screen - iphone

Question

I have an app where I play a movie after a touch on the view and then when the movie is finished. I place a button on the view. On clicking the button a second movie plays. But it seems that it is only then loaded and a short black screen appears. I want to avoid the black screen now...
Heres the code:
Initialization in viewDidLoad
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
NSString *movpath = [[NSBundle mainBundle]
pathForResource:#"movie1"
ofType:#"m4v"];
mpviewController =
[[MPMoviePlayerViewController alloc]
initWithContentURL:[NSURL fileURLWithPath:movpath]];
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:#selector(movieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:nil];
mp = [mpviewController moviePlayer];
// [mp setMovieControlMode:MPMovieControlModeHidden];
// [mp.view setFrame:CGRectMake(0, 0, 250, 263)];
mp.controlStyle = MPMovieControlStyleNone;
mp.shouldAutoplay = NO;
[mp prepareToPlay];
[mp pause];
then on a storyboard touch I call startAnimation
- (IBAction)startAnimation:(id)sender {
NSLog(#"Animation 1");
[self.view addSubview:mpviewController.view];
[mp play];
}
after this movie finishes I set the button
- (void) movieFinishedCallback:(NSNotification*) aNotification {
NSLog(#"...movie done");
// generate start button for animation 2
startAnimation2Button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
startAnimation2Button.tag = 1;
[startAnimation2Button addTarget:self action:#selector(startAnimation2:) forControlEvents:UIControlEventTouchUpInside];
startAnimation2Button.frame = CGRectMake(130, 230, 070, 070);
startAnimation2Button.userInteractionEnabled = YES;
startAnimation2Button.alpha = 0.1;
[self.view addSubview:startAnimation2Button];
}
then after a touch on the button, the second animation starts
- (IBAction)startAnimation2:(id)sender {
NSLog(#"Animation 2");
NSString *movpath = [[NSBundle mainBundle]
pathForResource:#"movie2"
ofType:#"m4v"];
[mp setContentURL:[NSURL fileURLWithPath:movpath]];
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:#selector(movieFinishedCallback2:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:nil];
[mp play];
}
but here a short black screen appears, probably while movie2 is loaded and is then playing.
How can I avoid the black screen?

You will not be able to entirely get rid of the pre buffering delay (black phase) between the videos when using MPMoviePlayerController.
Use AVQueuePlayer instead.
AVQueuePlayer is a subclass of AVPlayer you use to play a number of items in sequence.
See other questions and issues on that matter.
