From 16c472c201c197d3660334df5952eb4084897f9f Mon Sep 17 00:00:00 2001 From: Jean-Michel Trivi Date: Thu, 8 Aug 2013 18:32:55 -0700 Subject: AAC encoder metadata improvement AAC-Encoder - Introduce metadata support for parametric stereo audio object type. Write metadata matrix mixdown coefficient only for channel config 5 and 6. Modified file(s): libAACenc/src/aacenc_lib.cpp - Revise metadata encoder downmix gain and fix matrix mixdown coefficient.
