movie orientation
<p>How can I detect a movie orientation (portrait or landscape) or width and height of it?
For example, when using UIImagePickerController:</p>

<pre><code>- (void)imagePickerController:(UIImagePickerController*)picker didFinishPickingMediaWithInfo:(NSDictionary*)info {
    if ([[info valueForKey:UIImagePickerControllerMediaType] isEqualToString:(NSString*)kUTTypeMovie]) {
        NSURL *videoURL = [info valueForKey:UIImagePickerControllerMediaURL];
    }
}
</code></pre>

<p>how can I get this information from videoURL?</p>

<p>Now I'm trying to locate a video thumbnail images in /tmp directory and work with them but this method is not stable.</p>

<p>Thanks in advance.</p>
