FAAD2 Dependencies
Required
Installation of FAAD2
Install FAAD2 by running the following commands:
mkdir build &&
cd build &&
cmake -DCMAKE_INSTALL_PREFIX=/usr \
-DCMAKE_BUILD_TYPE=Release \
-DBUILD_SHARED_LIBS=ON \
.. &&
make
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-1.2.10 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
