From 43b378a0d321e3d01f196cec95e13acfac80d464 Mon Sep 17 00:00:00 2001 From: Rostislav Pehlivanov Date: Fri, 21 Aug 2015 18:53:14 +0100 Subject: [PATCH] aaccoder: move the quantization functions to a separate file This commit moves the quantizer to a separate header file. This allows the quantizer to be used from a separate files outside of aaccoder without having to put another function pointer and will result in a slight speedup as the compiler can do more optimizations. This is required for commits following.
