Is this a qualified OOP script in PHP?

class Youtube
{
    private $url = null;
    private $id;

    public function __construct($url)
    {
        $this->url = $url;
        $this->parseUrl($url);
    }

    protected function parseUrl($url)
    {

        if (preg_match('%(?:youtube(?:-nocookie)?\.com/(?:[^/]+/.+/|(?:v|e(?:mbed)?)/|.*[?&]v=)|youtu\.be/)([^"&?/ ]{11})%i', $url, $match)) {
            $this->id = $match[1];
        }
        else
        {
            throw new exception('Cannot find an ID!');
        }

    }

    public function getVideo($width='560', $height='315')
    {
        $video = id" frameborder="0" allowfullscreen>
EOF;

        return $video;
    }

}

$sistar = new Youtube('http://www.youtube.com/watch?v=JtVhwsACgTw');
print $sistar->getVideo();

$twoneone = new Youtube('http://www.youtube.com/watch?v=LUrUPzLm5SI');
print $twoneone->getVideo();

This is my first object-oriented script in PHP (I hope it's not too bad in general). I know I should do more validation and commenting within the code. Do you have any suggestions for improving the quality of the code?

Pinoniq has the right idea, which can be taken a bit further:

VideoFactory $vf = new VideoFactory();
Video $video = $vf->createVideo( "http://youtube.com/..." );
$video->setDimensions( 640, 480 );
$video->embed();

Here, the VideoFactory can parse a URL. The createVideo method would return a subclass of Video, which is a YouTubeVideo. However, the implementation need not be dependent on YouTube. This allows you to also write:

VideoFactory $vf = new VideoFactory();
Video $video = $vf->createVideo( "http://vimeo.com/..." );
$video->setDimensions( 640, 480 );
$video->embed();

You'll note that the only item that changed is the URL, but both video formats can be embedded.
