From 7686c950b563b63bd39f3699558bb22ba965274b Mon Sep 17 00:00:00 2001 From: Jingning Han Date: Wed, 12 Mar 2014 10:03:28 -0700 Subject: [PATCH] Tune rate-distortion modeling for non-RD mode decision This commit adjusts the rate-distortion modeling for non-RD mode decision. It puts more weights on energy from AC coefficients when estimating the cost. The coding performance for rtc testset is improved by 0.72%.
