(Floe) Video Player Wordpress Plugin

Overview

The Floe Video Player Wordpress Plugin allows a Wordpress editor to bring together video content, captions, and transcripts into a single experience.

Is any other information required? i.e. author, description / summary, primary language, etc?
Are any of the fields mandatory? I assume Video URL and format are required.
How common is the Amara use case for either Transcript or Captions?
Can JSONcc or VTT resources be loaded from an URL?
Can the type of caption / transcript be detected given an URL?
Can an Amara transcript or Amara caption be uploaded locally or must it always
