Video filter is a highly flexible and easy extendable filter module to embed any type of video in your site using a simple tag.

Code

function video_filter_get_classes($video) {
  $classes = array(
    'video-filter',
    
    // Add codec name.
    'video-' . $video['codec']['codec_name'],
  );

  // Add alignment.
  if (isset($video['align'])) {
    $classes[] = 'video-' . $video['align'];
  }

  // First match is the URL, we don't want that as a class.
  unset($video['codec']['matches'][0]);
  foreach ($video['codec']['matches'] as $match) {
    $classes[] = 'vf-' . strtolower(preg_replace('/[^a-zA-Z0-9]/', '', $match));
  }

  return $classes;
}
