The |slice_qp_detla| reported by the hardware is not credible, which causing the quality scaler cannot work properly,the resolution cannot be adjusted correctly. To fix this issue, this CL implements a bandwidth scaler which is used for adjust resolution, this scaler will be used when QP based quality scaler is not working due to untrusted QP reported by HW AVC encoder.
