  // We use these defaults to filter arrays for their height and width, and assign a fallback value
  $defaults = array(
    'height' => '100%',
    'width' => '100%',
  );

  // If height and width are already set then just return
  if (count(array_intersect_key($options['othervars'], $defaults)) == 2) {
    return;
  }

  // See if we can get height and width from flashvars
  $try = array_intersect_key($options['flashvars'], $defaults);
  $options['othervars'] += $try;

  // See if we can get height and width from player
  $try = array_intersect_key($options['resolved_methods']['player'], $defaults);
  $options['othervars'] += $try;

  // If we have a height and width now then return
  if (count(array_intersect_key($options['othervars'], $defaults)) == 2) {
    return;
  }

  // Try and get size from the file to be embedded, but preserve height or width if just one was set
  $info = swftools_get_info($options['othervars']['filepath']);

  // If sizes were retrieved then use them
  if ($info) {
    $try = array_intersect_key($info, $defaults);
    $options['othervars'] += $try;
  }

  // And if all else fails, assign 100%
  $options['othervars'] += $defaults;
