Developing iPhone Application, How do i get video "length" from a video saved to my app docs folder?

Question

Basically i record / import video , it saves to the docs folder and im trying to figure out how to get the length (time) so i can display it for each individual video..

I have a column in the database for it and the neccessary code to display it, just not sure how to get it..

Any help is greatly appreciated

You can get the path to the document and pass it as a file URL into the MediaPlayer framework to get info about the video file. Here's code to get the duration in seconds of a movie file:

NSArray *docsPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsFolder = [docsPaths objectAtIndex:0];
NSString *movieFilePath = [documentsFolder stringByAppendingPathComponent:@"Movie.mov"];
MPMoviePlayerController *player = [[[MPMoviePlayerController alloc] initWithContentURL] autorelease];
NSTimeInterval duration = player.duration; // in seconds
