Converts the constant rddiv parameter to 128 (from 100) and implements RDCOST with bit-shift rather than multiplication. Other parameters are also adjusted to roughly keep the same balance between Rate and Distortion. There is a slight speed-up of about 0.5-1% (at speed 0) as testted on football_cif. There is a slight change in performance due to small change in the parameters. derfraw300: +0.033% stdhdraw250; +0.102% Change-Id: I70ac69f58fa71c83108f68fe41796cd19d1fc760
