我想从视频列表中获取视频标题。
--flat-playlist选项返回视频ID，但我找不到返回视频标题的选项。
youtube-dl --flat-playlist "https://app.pluralsight.com/library/courses/openid-and-oauth2-securing-angular-apps"
[pluralsight:course] openid-and-oauth2-securing-angular-apps: Downloading JSON metadata

--get-filename选项和--get-title选项仅打印第一个视频的名称，然后他们抛出ExtractorError('No video formats found')：
youtube-dl --get-title "https://app.pluralsight.com/library/courses/openid-and-oauth2-securing-angular-apps" --verbose
