iPhone :How to get duration of video selected from library?

Question

I am using UIImagePickerController to choose video file from library. And user can upload the video.

Also I am using videoMaximumDuration p

Answer 1

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

#import 

-(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);
}
