Java 如何让Youtube API自动同步我的视频标题？

我正试图上传字幕到我的youtube视频，但失败了。请帮忙。谢谢

我的代码：

{

    // This OAuth 2.0 access scope allows for full read/write access to the
    // authenticated user's account and requires requests to use an SSL connection.
    List<String> scopes = Lists.newArrayList("https://www.googleapis.com/auth/youtube.force-ssl");
    // Authorize the request.
    Credential credential = Auth.authorize(scopes, "captions");

    youtube = new YouTube.Builder(Auth.HTTP_TRANSPORT, Auth.JSON_FACTORY, credential)
        .setApplicationName("youtube-cmdline-captions-sample").build();

    Caption captionObjectDefiningMetadata = new Caption();

    CaptionSnippet snippet = new CaptionSnippet();

    snippet.setVideoId(videoId);
    snippet.setLanguage("en");
    snippet.setName("caption");

    snippet.setIsAutoSynced(true);

    captionObjectDefiningMetadata.setSnippet(snippet);

    InputStreamContent mediaContent = new InputStreamContent(
        CAPTION_FILE_FORMAT,
        new BufferedInputStream(new FileInputStream(captionFile)));
    mediaContent.setLength(captionFile.length());

    Insert captionInsert = youtube.captions().insert("snippet",
        captionObjectDefiningMetadata, mediaContent);

    MediaHttpUploader uploader = captionInsert.getMediaHttpUploader();

    uploader.setDirectUploadEnabled(false);

    // Upload the caption track.
    Caption uploadedCaption = captionInsert.execute();
}

我注意到，如果我删除setIsAutoSync行，它将上载，但它不会自动同步我的标题。非常感谢您的帮助。谢谢。

您不应该设置“自动同步”选项，请尝试设置“同步”选项。 这对我有用。 或者在插入标题后更新标题
