Methods

apply_()

Reapply the effects of |this.rate_| and |this.active_| to the media element. This will only update the rate via the harness if the desired rate has changed.
Source:

applyRate_(newRate) → {boolean}

If the new rate is different than the media element's playback rate, this will change the playback rate. If the rate does not need to change, it will not be set. This will avoid unnecessary ratechange events.

Harness

A layer of abstraction between the controller and what it is controlling. In tests this will be implemented with spies. In production this will be implemented using a media element.
Type:
  • {getRate: function(): number, getDefaultRate: function(): number, setRate: function(number), movePlayhead: function(number)}
Properties:
Name Type Description
getRate function Get the current playback rate being seen by the user.
getDefaultRate function Get the default playback rate that the user should see.
