    <thetext>subtask of bug 264134

Currently the MediaSource::monitorSourceBuffer requires the mediaElement&apos;s currentTime.

But to do so, it directly access the HTMLMediaElement::currentMediaTime [1]

As the MediaSource may not be running in the same thread in the future, it may not be safe for the MediaSource to directly access the MediaElement.

An alternative would be to access the MediaPlayer instead, which has a more up to date value of the current time.
