YouTube Data API v3 Direct Form Upload - youtube

Question

I had a system setup with the YouTube Data API v2 that would let a user upload a video directly to MY YouTube account via a form on my site (I understand the implications of this, please keep in mind that I am just giving a bare bones description of what the tool did). I have so far been unable to figure out how to setup this same system with the v3 API now that v2 is deprecated. Another quick note, I would like to be able to do this without sending the user to the OAuth page since I have no need to access their YouTube account.
Here is a slimmed down version of PHP code that made this work for v2:
<?php
if ($_GET['op'] == "yt") {
if ($_GET['status'] == "200") {
// video upload was successful, $_GET['id'] contains the YouTube video ID for the upload
} else {
// video upload failed
}
} else {
require_once("Zend/Loader.php");
Zend_Loader::loadClass("Zend_Gdata_ClientLogin");
Zend_Loader::loadClass("Zend_Gdata_YouTube");
$httpClient = Zend_Gdata_ClientLogin::getHttpClient(
$username = "YOUTUBE_USERNAME",
$password = "YOUTUBE_PASSWORD",
$service = "youtube",
$client = null,
$source = "My Video Upload Bla Bla Bla",
$loginToken = null,
$loginCaptcha = null,
"https://www.google.com/accounts/ClientLogin"
);
$yt = new Zend_Gdata_YouTube($httpClient, "My Video Upload Bla Bla Bla", "My Video Upload Bla Bla Bla", "YOUTUBE_DEVELOPER_KEY");
$yt->setMajorProtocolVersion(2);
$myVideoEntry = new Zend_Gdata_YouTube_VideoEntry();
$myVideoEntry->setVideoTitle("Video Title");
$myVideoEntry->setVideoDescription("Video Description");
$myVideoEntry->setVideoCategory("People");
$accessControlElement = new Zend_Gdata_App_Extension_Element("yt:accessControl", "yt", "http://gdata.youtube.com/schemas/2007", "");
$accessControlElement->setExtensionAttributes(array(
array("namespaceUri" => "", "name" => "action", "value" => "list"),
array("namespaceUri" => "", "name" => "permission", "value" => "denied")
));
$myVideoEntry->setExtensionElements(array($accessControlElement));
$tokenArray = $yt->getFormUploadToken($myVideoEntry, "http://gdata.youtube.com/action/GetUploadToken");
$nextUrl = urlencode("http://{$_SERVER['HTTP_HOST']}{$_SERVER['PHP_SELF']}?op=yt");
print "<form action=\"{$tokenArray['url']}?nexturl={$nextUrl}\" method=\"POST\" enctype=\"multipart/form-data\">\n";
print " <input name=\"file\" type=\"file\" />\n";
print " <input name=\"token\" type=\"hidden\" value=\"{$tokenArray['token']}\" />\n";
print " <input value=\"Upload Video File\" type=\"submit\" />\n";
print "</form>\n";
}
?>

I found an excellent article that helped me with this:

A couple of things to point out if you use this article to help you with the same problem. The CURL call to http://gdata.youtube.com/action/GetUploadToken needs to be to HTTPS not HTTP and the form action="{{post_url}}?next={{next_url}} needs to be action="{{post_url}}?nexturl={{next_url}}.
