使用 Youtube API v3 可恢复上传（在 AWS EC2 上）上传较大的视频时出错

Question

在我的 AWS EC2 实例上，我可以使用 Youtube API (PHP) 上传视频。我的视频文件存储在 AWS S3 上，所以当上传到 Youtube 时，我的 PHP 脚本会将文件下载到 EC2，然后使用 Youtube API 上传到 Youtube。

这似乎适用于小于 100MB 的视频，但不适用于大于 100MB 的文件。

有人知道问题可能是什么吗？以下是用于执行上传的库代码的 sn-p：

$snippet = new \Google_Service_YouTube_VideoSnippet();
if (array_key_exists('title', $data))
{
    $snippet->setTitle($data['title']);
}
if (array_key_exists('description', $data))
{
    $snippet->setDescription($data['description']);
}
if (array_key_exists('tags', $data))
{
    $snippet->setTags($data['tags']);
}
if (array_key_exists('category_id', $data))
{
    $snippet->setCategoryId($data['category_id']);
}


/* ------------------------------------
#. Set the Privacy Status
------------------------------------ */
$status = new \Google_Service_YouTube_VideoStatus();
$status->privacyStatus = $privacyStatus;

/* ------------------------------------
#. Set the Snippet & Status
------------------------------------ */
$video = new \Google_Service_YouTube_Video();
$video->setSnippet($snippet);
$video->setStatus($status);

/* ------------------------------------
#. Set the Chunk Size
------------------------------------ */
$chunkSize = 1 * 1024 * 1024;

/* ------------------------------------
#. Set the defer to true
------------------------------------ */
$this->client->setDefer(true);

/* ------------------------------------
#. Build the request
------------------------------------ */
$insert = $this->youtube->videos->insert('status,snippet', $video);

/* ------------------------------------
#. Upload
------------------------------------ */
$media = new \Google_Http_MediaFileUpload(
    $this->client,
    $insert,
    'video/*',
    null,
    true,
    $chunkSize
);

/* ------------------------------------
#. Set the Filesize
------------------------------------ */
$media->setFileSize(filesize($path));

/* ------------------------------------
#. Read the file and upload in chunks
------------------------------------ */
$status = false;
$handle = fopen($path, "rb");

while (!$status && !feof($handle)) {
    $chunk = fread($handle, $chunkSize);
    $status = $media->nextChunk($chunk);
}

fclose($handle);

/* ------------------------------------
#. Set the defer to false again
------------------------------------ */
$this->client->setDefer(true);

我打开 CURLOPT_VERBOSE 来查看上传过程中的输出，下面是它的摘录：

好像上传了一段时间后，上传会突然停止。我以为可能是服务器内存限制，所以我升级了EC2实例类型，解决了这个视频文件的问题，但是当上传另一个更大的文件时，同样的事情又发生了。

在这里回答我自己的问题，以防它可以帮助其他人：

诀窍是增加块大小，以便一次将更大的块发送到 YouTube。解决方案来自这里：
