通过YouTube API上传时,视频文件停留在0%

Question

如标题所示,可以通过YouTube的上传功能上传和处理视频文件.但是,当我尝试以编程方式(通过OAuth2和YouTube API v3)上传时,它始终处于0%处理状态.在SO上有任何youtubers吗？是否有一些特殊的上传问题论坛？(PS,有一个类似的问题没有结果.)

更新错误:深入挖掘,似乎与视频元数据有关.偶尔会出现以下错误:

无法启动可恢复上传(HTTP 400:youtube.video,请求元数据指定无效的视频标题.)

不幸的是,YouTube的API v3的错误页面并没有真正遭受logorrhoea ...有谁知道这个错误意味着什么？

更新的代码: 目前文件是按块块上传的(通常效果很好,但不是所有时间):

    function uploadFile($dbfile) {
        $client = $this->client;
        $youtube = new Google_Service_YouTube($client);
        $htmlBody = "";
        try {

            // Create a snippet with title, description, tags and category ID
            // Create an asset resource and set its snippet metadata and type.
            // This example sets the video's title, description, keyword tags, and
            // video category.
            $snippet = new Google_Service_YouTube_VideoSnippet();
            $snippet->setTitle($dbfile->displayname);
            // Numeric video category. See
            // https://developers.google.com/youtube/v3/docs/videoCategories/list 
            $snippet->setCategoryId("22");

            // Set the video's status to "private"
            $status = new Google_Service_YouTube_VideoStatus();
            $status->privacyStatus = "private";

            // Associate the snippet and status objects with a new video resource.
            $video = new Google_Service_YouTube_Video();
            $video->setSnippet($snippet);
            $video->setStatus($status);

            $chunkSizeBytes = 1 * 1024 * 1024;
            $client->setDefer(true);

            $insertRequest = $youtube->videos->insert("status,snippet", $video);

            // Create a MediaFileUpload object for resumable uploads.
            $media = new Google_Http_MediaFileUpload(
                $client,
                $insertRequest,
                'video/*',
                null,
                true,
                $chunkSizeBytes
            );
            $media->setFileSize(filesize($dbfile->localfile));

            // Read the media file and upload it chunk by chunk.
            $status = false;
            $handle = fopen($dbfile->localfile, "rb");
            while (!$status && !feof($handle)) {
              $chunk = fread($handle, $chunkSizeBytes);
              $status = $media->nextChunk($chunk);
            }

            fclose($handle);
            $client->setDefer(false);

            $log = array("success" => true, "snippet_id" => $status["id"]);
        } catch (Google_ServiceException $e) {
            $log = array("success" => false, "errormsg" => $e->getMessage());
        } catch (Google_Exception $e) {
            $log = array("success" => false, "errormsg" => $e->getMessage());
        }
        return $log;
    }

那么，视频未处理可能还有其他问题，但我的问题是要插入的视频标题太长。YouTube 的字符数限制为不超过 100 个。如果您尝试插入更长的视频标题，则会引发上述异常。也许他们应该在 API 文档中的某个地方注明这一点。
