setPositionState method
The setPositionState() method of the
MediaSession interface is used to update the current
document's media playback position and speed for presentation by user's
device in any
kind of interface that provides details about ongoing media. This can be
particularly useful if your code implements a player for type of media not
directly
supported by the browser.
Call this method on the navigator object's
navigator.mediaSession object.
Implementation
external void setPositionState([MediaPositionState state]);
