How to use oembed to stretch your thumbs with youtube

I show a lot of thumbs on my homepage from a YouTube video. I used this function below to grab a thumb from a youtube url, which is fast, but it doesn’t work for url in short form like youtu.be/JSHDLSKL.

function get_youtube_screen_link( $url = '', $type = 'default', $echo = true ) {
if( empty( $url ) )
    return false;

if( !isset( $type ) )
    $type = '';

$url = esc_url( $url );

preg_match("|[\\?&]v=([^&#]*)|",$url,$vid_id);

if( !isset( $vid_id[1] ) )
    return false;

$img_server_num =  'i'. rand(1,4);

switch( $type ) {
    case 'large':
        $img_link = "http://{$img_server_num}.ytimg.com/vi/{$vid_id[1]}/0.jpg";
        break;
    case 'first':
        // Thumbnail of the first frame
        $img_link = "http://{$img_server_num}.ytimg.com/vi/{$vid_id[1]}/1.jpg";
        break;
    case 'small':
        // Thumbnail of a later frame(i'm not sure how they determine this)
        $img_link = "http://{$img_server_num}.ytimg.com/vi/{$vid_id[1]}/2.jpg";
        break;
    case 'default':
    case '':
    default:
        $img_link = "http://{$img_server_num}.ytimg.com/vi/{$vid_id[1]}/default.jpg";
        break;
}
if( $echo )
    echo $img_link;
else
    return $img_link;

}

So, I tried using Oembed to get thumbs instead, which works for all variations of the youtube url, but it extracts a finger of 480px / 360px, which causes a lot of cropping to get it to the size of 120px / 90px, which I use to show their. Another problem was that my page speed increased by 4 seconds, and I think that this is a problem with how I implement it. This is what I call the thumb inside the loop.

<?php 
 require_once(ABSPATH.'wp-includes/class-oembed.php');
 $oembed= new WP_oEmbed;
 $name = get_post_meta($post->ID,'video_code',true);
 $url = $name;
//As noted in the comments below, you can auto-detect the video provider with the following
 $provider = $oembed->discover($name);
//$provider = 'http://www.youtube.com/oembed';
 $video = $oembed->fetch($provider, $url, array('width' => 300, 'height' => 175));
 $thumb = $video->thumbnail_url; if ($thumb) { ?>
   <img src="<?php echo $thumb; ?>" width="120px" height="90px" />
<?php } ?>
