From c0e99f84f9c2ff909020a7ce76f60d1f78b56fc7 Mon Sep 17 00:00:00 2001 From: Jingning Han Date: Tue, 25 Feb 2014 16:12:35 -0800 Subject: Use sub-pixel accuracy prediction non-RD mode This commit builds the actual prediction block in sub-pixel accuracy and uses which to calculate SAD for non-RD mode decision. In the trail run on pedestrian_area at 1080p, rtc speed -7 runtime goes from 23495 ms -> 25107 ms (7% slower). The compression performance is improved by 20.57% for rtc test set.
