Как загрузить на Youtube API v.3 видео через php скрипт по крону?

Третий день ищу ответа по гуглу, но так и не могу найти как сделать загрузку видео на ютуб без oauth авторизации. Т.е. есть веб сервер. Нужно, чтобы с него можно было загрузить видео в любой момент. Через авторизацию доступ дается на 3600 секунд. Дальше нужно обновлять доступ. Нашел в интернете следующее.
1. Нужно использовать oauthplayground . Но не понятно как его использовать через стандартную библиотеку гугла https://github.com/google/google-api-php-client

2. Написал (точнее нашел) рабочий код к этой библиотеке. Видео загружается нормально. Но опять вопрос с обновлением токена остался открытым.

3. Блоки кода с текстом "// added manualy" добавил только сейчас. До этого не использовал еще.

<?php

// Call set_include_path() as needed to point to your client library.
require_once '../yaVoice.ru/vendor/autoload.php';
session_start();

Что, где подправить, чтобы этот же код можно было выполнить еще раз, но без авторизации через веб страничку гугла после того, как токен умрет?
