The other answers to this question using AVPlayerItem didn't work for me, but this did using AVURLAsset:

#import <AVFoundation/AVFoundation.h>

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    NSURL *videoURL=[info objectForKey:@"UIImagePickerControllerMediaURL"];
    AVURLAsset *asset = [[AVURLAsset alloc] initWithURL:videoURL options:nil];

    NSTimeInterval durationInSeconds = 0.0;
    if (asset)
        durationInSeconds = CMTimeGetSeconds(asset.duration);
}

1) just add the AVFoundation framwork in your app

2) then import the header file to your controller

#import <AVFoundation/AVFoundation.h>

3) then add the above code written by victor.

NSURL *recordedTmpFile = [info objectForKey:UIImagePickerControllerMediaURL];

AVPlayerItem *playerItem = [AVPlayerItem playerItemWithURL:recordedTmpFile];

CMTime duration = playerItem.duration;
float seconds = CMTimeGetSeconds(duration);

MPMoviePlayerController has a property duration. 

@property (nonatomic, readonly) NSTimeInterval duration

Please note that this property is read-only.

As per documentation

If the duration of the movie is not known, the value in this property is 0.0. If the duration is subsequently determined, this property is updated and a MPMovieDurationAvailableNotification notification is posted.

But why you are preferring MPMoviewPlayerController? AVFoundation is much faster for this type of operation. And you don't need to wait for any notification like in MPMoviewPlayerController.

if you would like to go through AVAsset. Here is a exact answer : MPMoviePlayerController - Duration always 0

NSURL *recordedTmpFile = [info objectForKey:UIImagePickerControllerMediaURL];

AVPlayerItem *playerItem = [AVPlayerItem playerItemWithURL:recordedTmpFile];

CMTime duration = playerItem.duration;
float seconds = CMTimeGetSeconds(duration);
