User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/faad2
Install FAAD2 by running the following commands:
patch -Np1 -i ../faad2-2.7-mp4ff-1.patch && sed -i "s:AM_CONFIG_HEADER:AC_CONFIG_HEADERS:g" configure.in && sed -i "s:man_MANS:man1_MANS:g" frontend/Makefile.am && autoreconf -fi && ./configure --prefix=/usr --disable-static && make
This package does not come with a test suite. However, basic functionality can be tested by decoding the sample AAC file:
./frontend/faad -o sample.wav ../sample.aac
This should display a copyright message and the following information about the sample file:
sample.aac file info:
ADTS, 4.608 sec, 13 kbps, 16000 Hz
---------------------
| Config: 2 Ch |
---------------------
| Ch | Position |
---------------------
| 00 | Left front |
| 01 | Right front |
---------------------
Now play the result (requires the aplay program from the alsa-utils-1.0.27.2 package):
aplay sample.wav
aplay should identify the file as “Signed 16 bit Little Endian, Rate 16000 Hz, Stereo”, and you should hear some piano notes.
Now, as the root
user:
make install
sed -i ...: First command fixes autotools scripts to be compatible with latest version of Automake and second command fixes manual page install location.
--disable-static
: This
switch prevents installation of static versions of the libraries.
--with-drm
: This option is supposed to
enable support for decoding Digital Radio Mondiale, but actually
breaks the base functionality of the package (e.g., the resulting
faad program cannot
decode the sample AAC file linked above). Don't use it.
