faad is not updated since 2009 year, please disable it in vlc ebuilds and remove USE aac. By default vlc uses libavcodec from ffmpeg or libav for aac decoding, faad is disabled by default in configure script: $ sh ./configure --help|grep faad --enable-faad faad codec (default disabled) --with-faad-tree=PATH faad tree for static linking When USE aac is enabled, vlc will not use libavcodec for aac decoding, but will use faad.

I have renamed it to faad to differentiate it from aac; as long as it works and/or is supported, I don't mind keeping it around. + 26 Oct 2013; Tom Wijsman <TomWij@gentoo.org> metadata.xml, + vlc-2.0.9999.ebuild, vlc-2.1.9999.ebuild, vlc-9999.ebuild: + Renamed the aac USE flag to faad as with --disable-faad, libavcodec will do + aac decoding; documented the faad USE flag in metadata.xml; solution for bug + #476598, reported by Nikoli. It will be part of today's version bumps.
