MPMoviePlayerViewController plays a movie from the Documents directory - objective-c

Question

I have a subfolder called "Video" in the "Documents" folder. And there is somevideo.mp4 file. I have the full path to this file, but MPMoviePlayerViewController does not want to play the video from local. Here is the 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 does not play. A white screen appears and nothing else. This code works with the remote video when I put the URL on the website with the video file, but the local one does not play. How to get the correct path to the video file?

Answer 1

Do you use iOS prior to 4.3? If so, you need to do it.

 [videoPlayerView setContentURL: fURL]; 

Here is a snippet of code from which I am playing a video from a document folder. One of the things I would recommend is to avoid some auto-ad objects. Especially in NSURL when you have viewcontrollers. I know this should be safe, but I did not find it 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 usually do with all view controllers), so the references to the self will be associated with an instance of the MPMoviePlayerController object

It’s strange. The code you supplied seems to be correct. Make sure that the path to the audio you are trying to extract is not broken.
