Why isn't the scalingMode of my MPMoviePlayerController being respected when coming back from Full Screen?

Question

I have an instance of MPMoviePlayerController that is correctly displaying a HLS video stream on Portrait mode and also on Full Screen when I rotate my iPhone to the Landscape mode for the first time. The issue happens when I come back from Full Screen: the scalingMode property of my MPMoviePlayerController is still set to MPMovieScalingModeAspectFill but the video is displayed as it is set to MPMovieScalingModeAspectFit.

Before adding its view as a Subview (self.moviePlayer.view) of my View (self.movieView) I set its scalingMode to MPMovieScalingModeAspectFill and everything works fine untill I exit Full Screen.

- (void) play
{
    self.moviePlayer = [[MPMoviePlayerController alloc] init];

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayBackDidStart:) name:MPMoviePlayerLoadStateDidChangeNotification object:self.moviePlayer];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:self.moviePlayer];

    self.moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
    self.moviePlayer.contentURL = videoURL;
    self.moviePlayer.controlStyle = MPMovieControlStyleNone;
    self.moviePlayer.shouldAutoplay = YES;
    self.moviePlayer.scalingMode = MPMovieScalingModeAspectFill;
    NSLog(@"%ld", (long) self.moviePlayer.scalingMode);

    self.moviePlayer.view.frame = CGRectMake(0, 0, 320, 180);

    [self.movieView addSubview:self.moviePlayer.view];

    [self.moviePlayer setFullscreen:NO animated:NO];
}

When I return from Full Screen it is set to the default value (MPMovieScalingModeAspectFit) and I can't change it back to MPMovieScalingModeAspectFill even if I explicity try to when I receive the MPMoviePlayerScalingModeDidChangeNotification.

- (void)movieScalingModeDidChange:(NSNotification *)notification
{
    self.moviePlayer.scalingMode = MPMovieScalingModeAspectFill;
    NSLog(@"%ld", (long) self.moviePlayer.scalingMode);
}

The weird thing is that that this NSLog gives me:

-[CameraViewController play]:2

Which according to the Documentation is the enum for MPMovieScalinModeAspectFill, but the video is not it this aspect mode.

typedef enum {
   MPMovieScalingModeNone,
   MPMovieScalingModeAspectFit,
   MPMovieScalingModeAspectFill,
   MPMovieScalingModeFill
} MPMovieScalingMode;

Has anyone experienced this same issue? Thanks in advance!

You need change scalingMode to any value other than MPMovieScalingModeAspectFill and set aspect fit again on receiving MPMoviePlayerScalingModeDidChangeNotification

- (void)playerDidExitFullscreen:(NSNotification *)notification
{
    self.moviePlayer.scalingMode = MPMovieScalingModeNone;
    self.moviePlayer.scalingMode = MPMovieScalingModeAspectFill;
}

It works with tiny animation issue.
