BROWSER_GAP_TOLERANCE
The limit, in seconds, for the gap size that we will assume the browser will
handle for us.
config_ :shaka.extern.StreamingConfiguration
Type:
eventManager_ :shaka.util.EventManager
Type:
gapJumpTimer_ :shaka.util.Timer
We can't trust |readyState| or 'waiting' events on all platforms. To make
up for this, we poll the current time. If we think we are in a gap, jump
out of it.

Type:
- ?function(!Event)
stallDetector_ :shaka.media.StallDetector
The stall detector tries to keep the playhead moving forward. It is
managed by the gap-jumping controller to avoid conflicts. On some
platforms, the stall detector is not wanted, so it may be null.

Methods
onPollGapJump_()
Called on a recurring timer to check for gaps in the media. This is also
called in a 'waiting' event.
onSegmentAppended()
Called when a segment is appended by StreamingEngine, but not when a clear
is pending. This means StreamingEngine will continue buffering forward from
what is buffered. So we know about any gaps before the start.
release()
Request that this object release all internal references.
