Enable skipping reference frame check in rd loop This commit allows encoder to compare the SAD cost associated with the best motion vector predictor, per frame. If one reference frame has this cost more than 4 times of the best SAD cost given by other reference frames, skip NEARESTMV, NEARMV, ZEROMV mode check of this reference frame. This setting is turned on in speed 2 and above. Compression quality change in speed 2: derf -0.014% yt -0.097% hd -0.023% stdhd 0.046% It reduces the speed 2 runtime of test sequences: pedestrian_area_1080p 4000 kbps 310763 ms -> 303595 ms bluesky_1080p 6000 kbps 259852 ms -> 251920 ms Change-Id: I7f59cf79503d51836d61d56d50dc5bdf0e502e22
