==Overview==
This page describes how to play mp3 format audio streams and files on your Didj using madplay, a command-line mp3 player.

==Prerequisites==
In this example we assume you are using the buildcross-generated cross compiler environment http://elinux.org/Didj_Build_Environment and have properly set your environment variables for cross-compilation.

Download the latest sources for the following packages:

madplay-0.15.2b.tar.gz http://sourceforge.net/projects/mad/files/

libmad-0.15.1b.tar.gz http://sourceforge.net/projects/mad/files/

libid3tag-0.15.1b.tar.gz http://sourceforge.net/projects/mad/files/

zlib-1.2.5.tar.gz http://www.zlib.net/

==Building madplay==
Create a folder called madplay_build and then extract these archives into folders in madplay_build.

Set the following variables:
<code>
export CC=arm-linux-uclibcgnueabi-gcc
export CXX=arm-linux-uclibcgnueabi-gcc
export CPPFLAGS='-I/full/path/to/madplay_build/libmad-0.15.1b -I/full/path/to/madplay_build/libid3tag-0.15.1b -I/full/path/to/madplay_build/zlib-1.2.5'
export LDFLAGS='-L/full/path/to/madplay_build/libmad-0.15.1b -L/full/path/to/madplay_build/libid3tag-0.15.1b -L/full/path/to/madplay_build/zlib-1.2.5'
</code>

'''Build zlib'''

Enter the directory zlib-1.2.5 and run:

<code>
configure
</code>
then run

<code>
make
</code>

'''Build libid3tag'''

Enter the directory libid3tag-0.15.1b and type
<code>
configure --host=arm
</code>

then type
<code>
make
</code>

after which, type
<code>
cp .libs/libid3tag.a .
</code>
(note the trailing dot)

'''Build libmad'''

Enter the directory libmad-0.15.1b and type
<code>
configure --host=arm
</code>

''Note: Edit the Makefile, removing '-fforce-mem' from the CFLAGS directive.''

then type
<code>
make
</code>

after which, type
<code>
cp .libs/libmad.a .
</code>
(note the trailing dot)

'''Build madplay'''

Enter the directory madplay-0.15.2b and type
<code>
configure --host=arm
</code>

then type
<code>
make
</code>

Finally, strip the madplay file as follows:

<code>
arm-linux-uclibcgnueabi-strip madplay
</code>

'''Install madplay'''

Transfer the file, plus one or more MP3s of your choosing, to your Didj.

Make sure the lightning application is stopped.
On the Didj:
<code>
/etc/init.d/lightning stop
</code>

==Playing MP3s==

To execute madplay,
On the Didj:
<code>
madplay yourfile.mp3
</code>

==Streaming MP3s==

In order to stream a networked MP3 stream, first set up networking. (You can using the information in http://elinux.org/Didj_Networking_HOWTO and http://elinux.org/Route_Your_Didj to set up networking and routing)

To stream audio, wget a stream (the example is NPR news), while piping the stream through madplay:

<code>
wget -O - http://npr.ic.llnwd.net/stream/npr_live24 | ./madplay -
</code>
Note that .pls files are not supported in madplay. (but you can open them with a text editor to get the URL)

Enjoy the sound!
