/**
|
||
|
|
* 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.
