文档:

Allows showing or hiding the "Create Video Playlist" button in the media library.

By default, the "Create Video Playlist" button will always be shown in the media library. If this filter returns `null`, a query will be run to determine whether the media library contains any video items. This was the default behavior prior to version 4.8.0, but this query is expensive for large media libraries.
