  $params['secret'] = $this->config->item('google_consumer_secret');
  $params['algorithm'] = "HMAC-SHA1";    

  $this->load->library('google_oauth', $params);

  $token_secret = $this->session->userdata('token_secret'); //pseudo code for retrieving the stored value

  $oauth = $this->google_oauth->get_access_token(false, $token_secret);
  $this->session->set_userdata('youtube_token', $oauth['oauth_token']); //pseudo code for permanently storing this value
  $this->session->set_userdata('youtube_secret', $oauth['oauth_token_secret']); //pseudo code for permanently storing this value
    
  redirect('video/ytu');

function ytu() {
  $params['apikey'] = $this->config->item('ytApi');
  $params['oauth']['key'] = $this->config->item('ytClientId');
  $params['oauth']['secret'] = $this->config->item('ytClientSecret');
  $params['oauth']['algorithm'] = "HMAC-SHA1";
  $params['oauth']['access_token'] = array('oauth_token'=>urlencode($this->session->userdata('youtube_token')), 'oauth_token_secret'=>urlencode($this->session->userdata('youtube_secret')));

         ';
  if(!$this->youtube->getFormUploadToken($metadata)){
   echo 'nothing';
  }
  
}

EDIT:
woops!! solution to my code was
replacing

Code:

$params['oauth']['key'] = $this->config->item('ytClientId');
  $params['oauth']['secret'] = $this->config->item('ytClientSecret');

by

Code:

$params['oauth']['key'] =  $this->config->item('google_consumer_key');
  $params['oauth']['secret'] = $this->config->item('google_consumer_secret');
