/**
* Videojs "Autoplay Next" button.
*
* --- How to use ---
* Apply `useAutoplayNext` in your React component. It registers an effect that
* listens to the given Redux state, and returns a callback for you to mount the
* custom videojs component.
*
* --- Notes ---
* Usually, custom videojs components can just listen to videojs events, query
* states from `player` (e.g. player.paused()) and update accordingly. But since
* the state comes from Redux, there will be a need to listen and pass the info
* to videojs somehow.
*
* Instead of going through an 'effect->css->videojs' trip, we'll just listen to
* the Redux state through a normal effect to update the component.
*
* This file aims to encapsulate both the React and Videojs side of things
* through a single `useAutoplayNext` call.
