 *
 * #GDataYouTubeVideo is a subclass of #GDataEntry to represent a single video on YouTube, either when uploading or querying.
 *
 * #GDataYouTubeVideo implements #GDataCommentable, allowing comments on videos
 * to be queried and added. However, the initial version of the v3 YouTube API
 * does not currently support comments, so all #GDataCommentable calls will
 * fail. It is hoped that the YouTube API will regain support for comments in
 * future.
 *
 * For more details of YouTube’s GData API, see the
 * <ulink type="http" url="https://developers.google.com/youtube/v3/docs/">
 * online documentation</ulink>.
