From 42ed53f221dc6570b7f6e05ef93f38b7457a68d8 Mon Sep 17 00:00:00 2001 From: diego Date: Sat, 1 Jan 2011 14:27:41 +0000 Subject: libfaad2:/ Remove forked internal libfaad2 copy git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@32741 b3059339-0415-0410-9bf9-f77b7e298cf2 Remove AAC/FAAD2 installation instructions. There is nothing special about building and installing FAAD2, so there is no longer a need to keep maintaining instructions for it. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@32742 b3059339-0415-0410-9bf9-f77b7e298cf2 --- libfaad2/bits.c | 213 -------------------------------------------------------- 1 file changed, 213 deletions(-) delete mode 100644 libfaad2/bits.c (limited to 'libfaad2/bits.c') diff --git a/libfaad2/bits.c b/libfaad2/bits.c deleted file mode 100644 index 34efbd4f71..0000000000 --- a/libfaad2/bits.c +++ /dev/null @@ -1,213 +0,0 @@ -/* -** FAAD2 - Freeware Advanced Audio (AAC) Decoder including SBR decoding -** Copyright (C) 2003-2004 M.
