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).
Bug: none
