Remove Title of youtube video

Update: Try this one.. it works for youtube url in your post which is converted to iframe by wordpress.

   function remove_youtube_controls($code){
    if(strpos($code, 'youtu.be') !== false || strpos($code, 'youtube.com') !== false){
        $return = preg_replace("@src=(['\"])?([^'\">]*)@", "src=$1$2&showinfo=0&rel=0", $code);
        return $return;
    }
    return $code;
}

add_filter('embed_handler_html', 'remove_youtube_controls');
add_filter('embed_oembed_html', 'remove_youtube_controls');
