From what i have read apple doesnt expose the api to allow developers to get a thumbnail of a movie using the current sdk.
Can any one share some code as to how the
NSString *videoLink=[info objectForKey:@"UIImagePickerControllerMediaURL"];
MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:(NSURL*)videoLink];
UIImage *imageSel = [player thumbnailImageAtTime:1.0 timeOption:MPMovieTimeOptionNearestKeyFrame];
[player stop];
[player release];
