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，因此当上传到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。
对于小于100MB的视频似乎可以正常工作，但对于大于100MB的文件则不行。
任何人都知道可能是什么问题吗？以下是用于执行上传的库代码的片段:
$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);
我打开了CURLOPT_VERBOSE以查看上传期间的输出，以下是该内容的摘录:

上传一段时间后，上传似乎会突然停止。我认为可能是由于服务器的内存限制所致，所以我升级了EC2实例类型，从而解决了此视频文件的问题，但是当上传另一个更大的文件时，同样的事情再次发生。
最佳答案
在这里回答我自己的问题，以防其他问题:
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:
