I have been trying to get a video to play using MPMoviePlayerController for about a week with very little success! I have finally got it to the stage where it loads the video (or at least I presume it does as it can tell me the video duration).
However, my video never becomes playable therefore I am just presented with a black square.
My code is as follows:
- (void)loadMovieWithURL:(NSURL *)movieURL
{
NSLog( @"Video URL = '%@'", [movieURL path]);
NSData *data = [NSData dataWithContentsOfURL:movieURL];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayerPlaybackStateDidChange:) name:MPMoviePlayerPlaybackStateDidChangeNotification object:nil];
MPMoviePlayerController *mp = [[MPMoviePlayerController alloc] init];
self.moviePlayer = mp;
[self.moviePlayer.view setFrame:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
[self addSubview:self.moviePlayer.view];
[self.moviePlayer setContentURL:movieURL];
self.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
[self.moviePlayer setFullscreen:NO];
[self.moviePlayer setScalingMode:MPMovieScalingModeFill];
[self.moviePlayer setControlStyle:MPMovieControlStyleNone];
//[self.moviePlayer setShouldAutoplay:YES];
[self.moviePlayer prepareToPlay];
[self.moviePlayer play];
}
I am printing out a lot of the values to NSLog just to check them, so thought I should provide them below too just to give a better idea of what I'm seeing:

I did setup a notification to check for MPMoviePlayerLoadStateDidChangeNotification but it never changes. Has anyone had a similar issue, or know what could be wrong with my code? If you need anymore information feel free to ask.
EDIT 1 (Testing danh's code)
When using the following:
NSLog( @"Video URL = '%@'", [movieURL path]);
self.moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
self.moviePlayer.view.frame = self.bounds;
[self addSubview:self.moviePlayer.view];
[self.moviePlayer prepareToPlay];
//NSData *data = [NSData dataWithContentsOfURL:movieURL];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayerPlaybackStateDidChange:) name:MPMoviePlayerPlaybackStateDidChangeNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(moviePlayerLoadStateChanged:)
name:MPMoviePlayerLoadStateDidChangeNotification object:nil];
My logs are:

So it seems to be the same as the original code where moviePlayerLoadStateChanged is never called. However, I'm still confused as to how the MPMoviePlayerController can pick up the duration of the video if it is unable to load it? Could this be a codec issue? Is there any way to check whether or not the video will work at all after downloaded?
EDIT 2:
Okay this looks like a possible codec issue. I have now tried it with 2 similar URLs, 1 mov / 1 3gp, and the mov one will play with sound but no video whilst the 3gp briefly shows "loading" on the video screen but never changes to the loaded state when this disappears. Can anyone suggest a way of getting this working, or another movie player with more types supported?
