BufferedChangeEvent: addedRanges property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Note: This feature is available in Dedicated Web Workers.

The addedRanges read-only property of the BufferedChangeEvent interface returns a TimeRanges object representing the time ranges that were added to the associated ManagedSourceBuffer. These are the ranges added between the last updatestart and updateend events, during the most recent run of the coded frame processing algorithm.
