From 0ee981a355115c35cc9b6aa5066d6b7271c4b28a Mon Sep 17 00:00:00 2001 From: Miguel Freitas Date: Sun, 14 Jul 2002 23:33:35 +0000 Subject: merge FAAD2 - the GPL AAC decoder library. xine_decoder.c is working, but demux_qt must send some needed initialization data. currently it's hardcoded to play my test stream, so it's not usable yet.
