Youtube - viewing private videos when 'logged in' via API with owner's account

Is it possible to view your own private videos on a web page by logging in via the youtube API?

So if I have an authenticated session of some kind on the page, I can play my private video by doing something like: http://www.youtube.com/em开发者_如何学Gobed/gYD0lKSIwxY ?

This is how I change the status of a video. This allows me to change the private video to unlisted so I can view it from my site. I use a javascript timer and ajax to change it back to private AFTER it has started to play.

<?php
/**
 * Change the status of a video on youtube
 */
if (isset($_POST['video_id'])) {

    $video_id = stripslashes(strip_tags($_POST['video_id']));
    $status = (isset($_POST['status'])) ? stripslashes(strip_tags($_POST['status'])) : 'private';
    $sessionToken = 'your_session_token';
    define('YT_DEVELOPER_KEY', 'your_developer_key');

    $uploadURL = $uploadToken = null;

    try {
    $hCurl = curl_init();

    if (!$hCurl)
        throw new Exception('Failed to create cURL object');

    $videoPrivate = <<<mof
