MPMoviePlayerViewController play movie from Documents directory - objective-c

Question

I have subfolder called "Video" in Documents folder. And there is somevideo.mp4 file. I have full path to this file but MPMoviePlayerViewController doesn't want to play video from local. Here is code:

NSString *path = [[self getVideoFolderPath] stringByAppendingPathComponent:@"somevideo.mp4"];
NSURL *fURL = [NSURL fileURLWithPath:path];
MPMoviePlayerViewController *videoPlayerView = [[MPMoviePlayerViewController alloc] initWithContentURL:fURL];
[self presentMoviePlayerViewControllerAnimated:videoPlayerView];
[videoPlayerView.moviePlayer play];

It doesn't play. Appears white screen and nothing else. This code works with remote video, when i put URL to website with video file, but local doesn't play. How to get correct file path to video file?

Are you using iOS prior to 4.3? If so, you need to do this

[videoPlayerView setContentURL: fURL];

Here is a snippet of code from where I play video from the documents folder. One of the things I would recommend is to avoid some of the autorelease objects. Especially on NSURL when you have viewcontrollers. I know it should be safe but I've never found it to be 100%

if ( [[NSFileManager defaultManager] fileExistsAtPath:fullpathVideoFile] == NO )
    {
    NSLog(@"No video file found");
    return self;
    }

playbackURL = [[NSURL alloc] initFileURLWithPath:fullpathVideoFile isDirectory:NO];

if ( playbackURL == nil )
    {
    NSLog(@"playbackURL == nil");
    return self;
    }

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayerLoadedMovie:) name:@"MPMoviePlayerLoadStateDidChangeNotification" object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayerStartedMovie:) name:@"MPMoviePlayerNowPlayingMovieDidChangeNotification" object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayerFinishedMovie:) name:@"MPMoviePlayerPlaybackDidFinishNotification" object:nil];

[self setContentURL:playbackURL];

In my case, I created a subclass of MPMoviePlayerController (as I generally do with all view controllers) so the references to 'self' would be to the MPMoviePlayerController object instance

Strange. The code you put seems to be correct. Make sure the path to the audio you are trying to retrieve isn't broken.
