From cccad1c5de41e29d6cc64c6e11a1d91c8486d090 Mon Sep 17 00:00:00 2001 From: Jingning Han Date: Tue, 7 Jul 2015 11:36:05 -0700 Subject: Reduce dqcoeff array size in decoder The decoding process handles detokenization and reconstruction per transform block sequentially. There is no need to offset the dqcoeff buffer according to the transform block index. This allows to reduce the memory spill and improve cache performance.
