optional<int> min_frames: The minimum number frames to observe to make a
                          scaling decision.
Default: kMinFramesNeededToScale in quality_scaler.cc

optional<double> initial_scale_factor: The sample period scale factor.
Default: kSamplePeriodScaleFactor in quality_scaler.cc

optional<double> scale_factor: Option to use a reduced sampling interval when
                               last check did not result in an adaptation (if
                               unset the initial_scale_factor is used).
