我正在使用 Youtube API 从我在 Youtube 中的应用程序创建事件以进行实时流式传输。通过以下代码成功完成。但我的要求：
1) 我需要使用 youtube API 从我的应用程序界面开始直播。可以吗？
2）当我使用 youtube API 从应用程序创建事件时，它会自动进入Custom (more encoding options)类型。我需要在类型中创建实时流事件。Quick (using Google+ Hangouts On Air) 这可能吗？
我的代码：
<?php
// Call set_include_path() as needed to point to your client library.
require_once 'Google/autoload.php';
require_once 'Google/Client.php';
require_once 'Google/Service/YouTube.php';
session_start();
//'2015-08-28T00:00:00.000Z'
