   Can be used to wrap oEmbed response in html, depending on type and size of oEmbed.

   function wrap_oembed_dataparse($return, $data, $url) {
   
   	$mod = '';
   
   	if  (   ( $data->type == 'video' ) &&
   			( isset($data->width) ) && ( isset($data->height) ) &&
   			( round($data->height/$data->width, 2) == round( 3/4, 2) )
   		)
   	{
   		$mod = 'embed-responsive--4-3';
   	}
   
   	return '<div class="embed-responsive ' . $mod . '">' . $return . '</div>';
   }
   
   add_filter( 'oembed_dataparse', 'wrap_oembed_dataparse', 99, 4 );

   To use ‘oembed_dataparse’ for the first time, you might have to clear oEmbed post-meta cache:

   add_filter( 'oembed_ttl', function($ttl) {
   	  $GLOBALS['wp_embed']->usecache = 0;
               $ttl = 0;
               // House-cleanoing
               do_action( 'wpse_do_cleanup' );
   	return $ttl;
   });
   
   add_filter( 'embed_oembed_discover', function( $discover )
   {
       if( 1 === did_action( 'wpse_do_cleanup' ) )
           $GLOBALS['wp_embed']->usecache = 1;
       return $discover;
   } );
