Update video with YOUTUBE google-api-php-client - api

Question

I'm trying update the video metadata with Youtube API. The API which I'm using is google-api-php-client.
That API works perfectly in upload and delete processes, but when I want update the video info I don't know what parameters I have to use.
This is the code:
try
{
// Build the Needed Video Information
$snippet = new Google_VideoSnippet();
$snippet->setTitle($_POST['videoTitle']);
$snippet->setDescription($_POST['videoDescription']);
$snippet->setTags(array($_POST['videoTags']));
$snippet->setCategoryId(22);
// Set the Video Info and Status in the Main Tag
$video = new Google_Video();
$video->setSnippet($snippet);
// Send the video to the Google Youtube API
$created_file = $youtube->videos->update('snippet', $video, array(
WHAT PARAMETERS!!!???!!
));
// Get the information of the uploaded video
print_r($createdFile);
}
catch (Exception $ex)
{
echo $ex;
}
Someone knows this? ? i'd like keep using this API because all my aplication use it.
Thank you in advanced.

To update a video, first you need to use videos->list with id=video_id, then update the part intended, wrap all subparts till to the video itself into google objects, and send an update request. (We will work to make this simpler)
Here's an update tags sample which ultimately updates the video, you can use it.
/**
* This sample adds new tags to a YouTube video by:
*
* 1. Retrieving the video with "youtube.videos.list" method setting the "id" parameter
* 2. Appending new tags to Video Resource's snippet.tags[] list
* 3. Updating the video itself via youtube.videos.update API call, supplying a new video via a
* binary upload to replace the old one.
