Create LossNotificationController, which produces LossNotification
RTCP feedback messages when video packets/frames are lost.
(LossNotification messages are sent when an RTP gap is detected,
as well as when frames are later received which are undecodable
because of the missing frames due to the previously dropped packets.)
