Post large video to youtube via google php client

Question

I am trying to upload large videos to youtube via the latest version of the google client api (v3, latest checked out source)

I have it posting the videos, but the only way I can get it to work is by reading the entire video into a string, and then passing it via the data parameter.

I certainly do not want to read gigantic files into memory, but the api seems to offer no other way to do this. It seems to expect a string as the data parameter. Below is the code I'm using to post the video.

$snippet = new Google_VideoSnippet();
$snippet->setTitle("Test title2");
$snippet->setDescription("Test descrition");
$snippet->setTags(array("tag1", "tag2"));
$snippet->setCategoryId("22");

$status = new Google_VideoStatus();
$status->privacyStatus = "private";

$video = new Google_Video();
$video->setSnippet($snippet);
$video->setStatus($status);

$videoData = file_get_contents($pathToMyFile);
$youtubeService->videos->insert("status,snippet", $video, array("data" => $videoData, "mimeType" => "video/mp4"));

Is there any way to post the data in chunks, or stream the data in some way so as to avoid reading the entire file into memory?

It looks like this use case wasn't supported before. Here's a sample that works with the very latest version of the Google APIs PHP client (from https://code.google.com/p/google-api-php-client/source/checkout).

if ($client->getAccessToken()) {
  $videoPath = "path/to/foo.mp4";
  $snippet = new Google_VideoSnippet();
  $snippet->setTitle("Test title2");
  $snippet->setDescription("Test descrition");
  $snippet->setTags(array("tag1", "tag2"));
  $snippet->setCategoryId("22");

  $status = new Google_VideoStatus();
  $status->privacyStatus = "private";

  $video = new Google_Video();
  $video->setSnippet($snippet);
  $video->setStatus($status);

  $chunkSizeBytes = 1 * 1024 * 1024;
  $media = new Google_MediaFileUpload('video/mp4', null, true, $chunkSizeBytes);
  $media->setFileSize(filesize($videoPath));

  $result = $youtube->videos->insert("status,snippet", $video,
      array('mediaUpload' => $media));

  $status = false;
  $handle = fopen($videoPath, "rb");
  while (!$status && !feof($handle)) {
    $chunk = fread($handle, $chunkSizeBytes);
    $uploadStatus = $media->nextChunk($result, $chunk);
  }

  fclose($handle);
}
