From 17db5d00be2f005f11428edf0fd23265d04d100f Mon Sep 17 00:00:00 2001 From: Yaowu Xu Date: Mon, 11 Feb 2013 21:14:46 -0800 Subject: [PATCH] enable bitstream lossless support 1. Added a bit in frame header to to indicate if a frame is encoded in lossless mode, so decoder does not make the decision based on Q0 2. Minor changes to make sure that lossy coding works same as when the lossless experiment is not enabled. 3. Renamed function pointers for transforms to be consistent, using prefix fwd_txm and inv_txm for forward and inverse respectively To encode in lossless mode, using "--lossless=1 --min-q=0 --max-q=0" with vpxenc.
