Install FAAD2 by running the following commands:
./bootstrap && ./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-1.2.8 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
--disable-static: This
switch prevents installation of static versions of the libraries.
