SUPPORT FOR LIBAACPLUS HAS BEEN REMOVED FROM FFMPEG.
What follows is purely for historical interest.
HE-AAC audio v2 (with SBR + PS) is the superb audio encoder used to encode high quality audio at really low bitrates (32 kbit/s). Quote from Wikipedia "Data from this testing also indicated that some individuals confused 48 kbit/s encoded material with an uncompressed original."
In order to quickly compile your libaacplus library, you can type the following commands in your shell:
# apt-get install libfftw3-dev pkg-config autoconf automake libtool unzip $ wget http://tipok.org.ua/downloads/media/aacplus/libaacplus/libaacplus-2.0.2.tar.gz $ tar -xzf libaacplus-2.0.2.tar.gz $ cd libaacplus-2.0.2 $ ./autogen.sh --enable-shared --enable-static $ make # make install # ldconfig
P.S. If you are using Ubuntu, you'll most probably have to use
sudo for the last 2 commands, like:
$ sudo make install $ sudo ldconfig
In case that website above (hosting libaacplus) goes offline, you can download the copy of that tar.gz file from here: (MD5: 3fc15d5aa91d0e8b8f94acb6555103da)
$ wget http://ffmpeg.gusari.org/uploads/libaacplus-2.0.2.tar.gz

NOTE: libaacplus is a non-free library, so you won't be able to build GPL alike FFmpeg with this library, i.e. your FFmpeg will not be redistributable.
