From 1bf1428654d29e4debe269b424ea3d8d486c45df Mon Sep 17 00:00:00 2001 From: Jingning Han Date: Tue, 20 Aug 2013 10:33:42 -0700 Subject: Enable zero coeff check in sub8x8 UV rd loop Check the minimum rate-distortion cost of regular quantization and all zero coeffs cases in the sub8x8 inter prediction rd loop for luma components. Use this as the cumulative rdcost sent to UV rd estimation.
