Retrieving progress of Direct Upload using youtube gdata API

问题

I'm following along with the documentation about using the gData Youtube API for doing direct uploads with PHP. I can successfully upload videos, so thats all well and good. The part I'm having trouble figuring out, if its even possible is getting some upload progress status as in percent complete or number of bytes uploaded.

Here is the snippet of code where the upload happens.

 <?php 
try {
      $newEntry = $yt->insertEntry($myVideoEntry, $uploadUrl, 'Zend_Gdata_YouTube_VideoEntry');
    } catch (Zend_Gdata_App_HttpException $httpException) {
      echo $httpException->getRawResponseBody();
    } catch (Zend_Gdata_App_Exception $e) {
        echo $e->getMessage();
    }
?>

Anyone have any ideas how to update a $progess variable or something as this is uploading?
