http://wiki.codeigniter.ch/wiki/ci-wiki/OEmbed-Library

Библиотеку OEMBED для codeigniter.

ставим ее в папку /application/libraries/

и юзаем так: Либо делаем автолоад библиотеки в

/application/config/autoload.php

либо в самом коде делаем так

1 $this->load->library('oembed');

а там 


1 $params = array('type' => 'xml', 'cache' => TRUE);
2 $this->load->library('oembed', $params);

Имейте ввиду что не все провайдера дают возможность параметров. 

потом можно инфо про видеофайле узнать таким способом


1 $this->oembed->call('vimeo', 'http://vimeo.com/6972240');
2 $this->oembed->call('hulu', 'http://www.hulu.com/watch/105905/the-daily-show-with-jon-stewart-recap-week-of-oct-26-2009');
