Check YouTube video before embedding

I’m embedding those video’s with the shortcode and youtube url, but some url’s where not valid (anymore). I’ve build a check before I use your shortcode. It should be nice if this is implemented in your shortcode.

function yt_exists($videoID) {
  $theURL = "https://www.youtube.com/oembed?url=http://www.youtube.com/watch?v=$videoID&format=json";

  $curl = curl_init($theURL);
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

  $body = curl_exec($curl);
  curl_close($curl);

  $result = json_decode($body, true);

  if ($result['title']){
    return true;
  } else {
    return false;
  }
}

if (!get_field('youtube_url')) { continue;}

$url = get_field('youtube_url');
parse_str( parse_url( $url, PHP_URL_QUERY ), $my_array_of_vars );
if ($my_array_of_vars['v']){
  $youtubeid = $my_array_of_vars['v'];
} else {
  $youtubeid = str_replace("https://youtu.be/","",$url);
}

if ($youtubeid){
  if (!yt_exists($youtubeid)) { 
  echo do_shortcode('[fvplayer src="'.get_field('youtube_url').'" lightbox="true;250;150" caption="'.get_the_title().'"]');}
}
