The HTMLMediaElement.buffered
read-only property returns a new TimeRanges
object that indicates the ranges of the media source that the browser has buffered (if any) at the moment the buffered
property is accessed.
Note: This feature is not available in Web Workers.
Syntax
var timeRange = audioObject.buffered
Value
A TimeRanges
object. This object is normalized, which means that ranges are ordered, don't overlap, aren't empty, and don't touch (adjacent ranges are folded into one bigger range).
Example
var obj = document.createElement('video'); console.log(obj.buffered); // TimeRanges { length: 0 }
