      Adaptive motion control on ref and search range · a4ce53f1
      Jingning Han authored
      This commit takes a preliminary attempt to refine the motion search
      control. It detects the SAD associated with mv predictor per reference
      frame, and based on which to determine whether the encoder wants to
      reduce the motion search range (if the predicted mv provides fairly
      small SAD), or to skip the current reference frame (if there exists
      another ref frame that gives much smaller SAD cost).
      
      This feature is turned on in the settings of speed 1 and above.
