Enable adaptive pred filter type for sub8x8 This commit enables an adaptive prediction filter type selection for sub8x8 block sizes. In speed 1, it re-uses the filter type of collocated 8x8 block if it is tested in the rate-distortion optimization loop, for the sub8x8 blocks. Otherwise, it runs the normal test over all the three filter types. In speed 2, it re-uses the 8x8 block's prediction filter type, if available. Otherwise, force it to be EIGHTTAP. Compression and speed performance wise: speed 1 derf -0.266% yt -0.138% bus at 2000 kbps: 33766ms -> 30451ms (10% speed-up) football at 600 kbps: 48173ms -> 43786ms (9% speed-up) speed 2 derf -0.026% yt +0.134% bus at 2000 kbps: 18973ms -> 17698ms (6% speed-up) football at 600 kbps: 26748ms -> 25096ms (6% speed-up) Change-Id: I77e097533b969fd3472147225fa79fc98095d342
