使用YOUTUBE谷歌api php客户端更新视频

Question

我正在尝试使用Youtube API更新视频元数据。我使用的API是google-API-php-client。API在上传和删除过程中非常有效，但当我想要更新视频信息时，我不知道我必须使用什么参数

这是代码：

try
        {
            // Build the Needed Video Information
            $snippet = new Google_VideoSnippet();
            $snippet->setTitle($_POST['videoTitle']);
            $snippet->setDescription($_POST['videoDescription']);
            $snippet->setTags(array($_POST['videoTags']));
            $snippet->setCategoryId(22);
            // Set the Video Info and Status in the Main Tag
            $video = new Google_Video();
            $video->setSnippet($snippet);
            // Send the video to the Google Youtube API
            $created_file = $youtube->videos->update('snippet', $video, array(
                WHAT PARAMETERS!!!???!!
            ));
            // Get the information of the uploaded video
            print_r($createdFile);
        }
        catch (Exception $ex)
        {
            echo $ex;
        }

有人知道吗？我想继续使用这个API，因为我所有的应用程序都使用它。

提前谢谢。

要更新视频，首先需要使用id=video_id的videos->list，然后更新想要的部分，将视频本身的所有子部分包装到谷歌对象中，并发送更新请求。（我们将努力使其更简单）

这里有一个更新标签的例子，它最终会更新视频，你可以使用它

/**
 * This sample adds new tags to a YouTube video by:
 *
 * 1. Retrieving the video with "youtube.videos.list" method setting the "id" parameter
 * 2. Appending new tags to Video Resource's snippet.tags[] list
 * 3. Updating the video itself via youtube.videos.update API call, supplying a new video via a
 * binary upload to replace the old one.
