Installation of FAAD2

Install FAAD2 by running the following commands:

mkdir build &&
cd    build &&

      -DCMAKE_BUILD_TYPE=Release  \
      .. &&

This package does not come with a test suite. However, basic functionality can be tested by decoding the sample AAC file:

./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-1.2.11 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
