From f9f453ec8d59b69bc57763f3c4bf14527435297e Mon Sep 17 00:00:00 2001 From: Dmitry Kovalev Date: Wed, 17 Jul 2013 16:50:52 -0700 Subject: [PATCH] Removing kf_{y, uv}_mode_prob arrays from VP9Common. These arrays have constant values (no any updates). Removing two corresponding memcpy calls. Making a little cleanup in vp9_entropymode.h as well: removing redundant 'extern' keyword and moving all function declarations at the end.
