Should add the following as well:

root@raspberrypi:/home/pi/audiotools-2.21# apt-get install libmpg123-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
libmpg123-dev is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 81 not upgraded.

from python-audio-tools.

The problem I run into is that running:

% python setup.py build
% apt-get install libmpg123-dev
% python setup.py build
% python setup.py install

won't work as expected since Python's distutils caches a lot of stuff, so you'll need to remove the build/ directory after installing additional packages.

But if that doesn't solve the problem, perhaps running:

% echo "from audiotools.decoders import MP3Decoder" | python -

might help determine why it's not loading. There might a 32/64-bit library mismatch or some other strangeness at work.

Thanks for the input. I will try tonight and let you know how that works.

Hi,

Still receiving error when trying to run trackplay on an mp3.

However, I see the following when running python setup.py install:

Python Audio Tools 2.21 Setup

library present? used for download URL

libasound2 no ALSA output http://www.alsa-project.org
libcdio no CDDA data extraction http://www.gnu.org/software/libcdio/
libmpg123 yes MP3/MP2 decoding
libpulse no PulseAudio output http://www.freedesktop.org
mp3lame no MP3 encoding http://lame.sourceforge.net
opus no Opus encoding http://www.opus-codec.org
opusfile no Opus decoding http://www.opus-codec.org
twolame no MP2 encoding http://twolame.sourceforge.net
vorbisenc no Ogg Vorbis encoding http://www.xiph.org
vorbisfile no Ogg Vorbis decoding http://xiph.org

audiotools-config still shows mp2 and mp3 in red.

And when running trackplay I get the following:

library "libmp3lame" needed to support mp3 format
mp3lame can be downloaded from http://lame.sourceforge.net/
library "libmpg123" needed to support mp3 format
mpg123 can be downloaded from http://www.mpg123.org/
or check your system's package manager

When trying your other suggestion:

pi@raspberrypi ~/Desktop $ echo "from audiotools.decoders import MP3Decoder" | python -
pi@raspberrypi ~/Desktop $

Given the processor is ARM, I am not sure if there is 32/64 weirdness. Is there anything else I can try?

from python-audio-tools.

Ah, looks like you're missing libmp3lame which is needed for MP3 support, since the codec wants both the decoder and encoder in order to work. Try installing "lame" and "lame-dev", clean out the build/ directory and rebuild.

I haven't yet split the decoding and encoding prerequisites so that one can decode a file without also being able to encode it, but that is on my TODO list.

from python-audio-tools.

I was able to do the following steps and it works great now thanks!

sudo apt-get install python-dev python-gtk2
sudo apt-get install libcdio-dev libcdio-paranoia-dev libasound2 libasound2-dev
sudo apt-get install mpg123 twolame libtwolame-dev
sudo apt-get install mpg123 lame mp3gain libmp3lame-dev libmpg123-dev
sudo apt-get install vorbis-tools libvorbis-dev
sudo apt-get install opus-tools libopus-dev
FAAC/FAAD Installation (adapted from http://pierskennedy.wordpress.com/2013/03/28/python-audiotools-on-the-rpi/)
Edit your apt-get source list by adding another source. sudo nano /etc/apt/sources.list Paste in deb http://www.deb-multimedia.org/ wheezy main non-free on a new line. Save and exit.
sudo apt-get install debian-keyring
Next, we would perform sudo apt-get update, but it will complain that the public key for the new source is missing. You should probably go ahead and try it before continuing, because I would strongly recommend against blindly installing keys that you don't know what they are just because som random guy (me) told you so. apt-get will complain about key 07DC563D1F41B907 (which has fingerprint 1F41B907) is unknown.
The actions 4 and 5 need to be properly run as root (sudo bash, and then executing them), simply prepending every command with sudo did not do it for me.
gpg --keyserver pgp.mit.edu --recv-keys 1F41B907

Forgot to add the following changes to the setup.cfg file to force acceptance of different libraries not found with probe:
libcdio_paranoia:probe
libpulse:probe
alsa:probe
libmpg123:yes
vorbisfile:yes
opusfile:probe
mp3lame:yes
twolame:yes
vorbisenc:yes
opus:probe
