我可以同时上传youtube视频和缩略图吗

Question

我使用c#，我可以成功上传视频到youtube我的频道。现在我想上传包含缩略图的视频。我在调试中没有出错，但缩略图没有上传，这是我的代码：

    private static async Task Upload(FileInfo Vidf)
    {
        //2.1 Get credentials
        UserCredential credentials;
        //2.1.1 Use https://console.developers.google.com/ to get the json file (Credential section)
        using (var stream = new FileStream(APIjson, FileMode.Open, FileAccess.Read))
        {
            credentials = await GoogleWebAuthorizationBroker.AuthorizeAsync(
                GoogleClientSecrets.Load(stream).Secrets,
                new[] { YouTubeService.Scope.YoutubeUpload },
                "user",
                CancellationToken.None);
        }
        //2.2 Create a YoutubeService instance using our credentials
        var youtubeService = new YouTubeService(new BaseClientService.Initializer()
        {
            HttpClientInitializer = credentials,
            ApplicationName = Assembly.GetExecutingAssembly().GetName().Name
        });

        //2.3 Create a video object
        var video = new Video()
        {
            Id = Vidf.Name,
            Status = new VideoStatus
            {
                PrivacyStatus = "private"
            },
            Snippet = new VideoSnippet
            {
                Title = "...",
                Description = "...",
            }
        };
        var filePath = Vidf.FullName;
        filesize = Vidf.Length;
        //2.4 Read and insert the video in youtubeService
        using (var fileStream = new FileStream(filePath, FileMode.Open))
        {
            var videosInsertRequest = youtubeService.Videos.Insert(video, "snippet,status", fileStream, "video/*");
            videosInsertRequest.ProgressChanged += ProgressChanged;
            videosInsertRequest.ResponseReceived += ResponseReceived;
            //2.4.1 Wait for the upload process
            await videosInsertRequest.UploadAsync();
        }

        var tpath = Vidf.FullName.Replace("mp4", "jpg");
        using (var tStream = new FileStream(tpath, FileMode.Open))
        {
            var tInsertRequest = youtubeService.Thumbnails.Set(video.Id, tStream, "image/jpeg");
            tInsertRequest.ProgressChanged += ProgressChanged;
            await tInsertRequest.UploadAsync();
        }
    }

我必须先上传视频，然后等待youtube处理完视频。然后上传缩略图，如此链接中的示例代码https://developers.google.com/youtube/v3/docs/thumbnails/set#examples

Answer 1

创建一个全局var"VidID"并在ResponseReceived函数中设置值

static void ResponseReceived(Video video)
    {
        VidID = video.Id;
    }

应该获取视频ID，然后发布带有该视频ID的缩略图。
