From 276df9d8210121f6d59b7876e1724ebe7a11f5e5 Mon Sep 17 00:00:00 2001 From: Nathan Caldwell Date: Mon, 25 Oct 2010 06:15:21 +0000 Subject: aacenc: Fix bug in LAME windowing where only one channel got initalized I used the same loop counter for the inner and outer initalization loops. This caused initalization to only run for the first channel. This in turn lead to any channel other than the first using only short blocks.
