Title Body

I am trying to get the thumbnail of the video which is pick up from library using the UIImagePickerController. Here is my code. I can get the the thumbnail of video if I using the camera to record a video. But I can not get the thumbnail if I pick up a video from the library. Anybody know why? -(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType]; if ([mediaType isEqualToString:(NSString *)kUTTypeMovie]) { NSURL *mediaUrl = [info objectForKey:UIImagePickerControllerMediaURL]; MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:mediaUrl]; moviePlayer.shouldAutoplay = NO; UIImage *thumbnail = [[moviePlayer thumbnailImageAtTime:0.0 timeOption:MPMovieTimeOptionNearestKeyFrame] retain]; [imageView setImage:thumbnail]; //imageView is a UIImageView [moviePlayer release]; [thumbnail release]; [self dismissModalViewControllerAnimated:YES]; } }
