-// A class responsible for measuring how much disk there is left when we
-// store our video to disk, and how much recording time that equates to.
-// It gets callbacks from the Mux writing the stream to disk (which also
-// knows which filesystem the file is going to), makes its calculations,
-// and calls back to the MainWindow, which shows it to the user.
-//
-// The bitrate is measured over a simple 30-second sliding window.
