You can try setting up your include path, and then calling Gdata clases from inside the controller

Copy the Zend Directory inside your library directory

Code:

set_include_path(get_include_path().PATH_SEPARATOR.FCPATH.'/application/libraries');

require_once 'Zend/Loader.php';
Zend_Loader::loadClass('Zend_Gdata_YouTube');
$yt = new Zend_Gdata_YouTube();

BTW, this code is not complete/validated, keep trying.
