From: Jingning Han Date: Sat, 22 Feb 2014 02:25:43 +0000 (-0800) Subject: Periodically update mode and mv costs X-Git-Tag: v1.4.0~2285^2 X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=836252bfa6338ca29bbfe3c9ccc8798ea32140d2;p=libvpx Periodically update mode and mv costs Skip coefficient cost update in non-RD mode decision setting. Allow periodical mode and motion vector cost update. Currently every other 8 frames. The increment runtime is a constant number. Hence more visible for CIF resolution, while negligible for 1080p. Speed -6 compression performance for rtc set is improved by 4.5%.
