From 6ecdf603b4f77c8785dd010bbaa71709db9bb4af Mon Sep 17 00:00:00 2001 From: Ram Mohan Date: Thu, 23 Nov 2017 17:43:35 +0530 Subject: [PATCH] avcenc: Disable SKIP_BIAS For static content, intra modes and skip mode compete with each other neck and neck. From bitstream perspective its favourable to pick skip. But do not over bias towards skip as intra modes are already being penalized with mode bits * lambda. Average bdrates improve by 1% Test: Tested on clips of different resolutions for quality changes Change-Id: I8ae85e7e807c9810e10b325627c84eec679327a9 --- encoder/ih264e_me.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/encoder/ih264e_me.h b/encoder/ih264e_me.h index da910c1..2266e5a 100644 --- a/encoder/ih264e_me.h +++ b/encoder/ih264e_me.h @@ -46,14 +46,14 @@ * @brief Skip Bias value for P slice ****************************************************************************** */ -#define SKIP_BIAS_P 2 +#define SKIP_BIAS_P 0 /** ****************************************************************************** * @brief Skip Bias value for B slice ****************************************************************************** */ -#define SKIP_BIAS_B 16 +#define SKIP_BIAS_B 0 /*****************************************************************************/
