what u need:
mpg123 (http://www.mpg123.de/)
standard on many distributions
RH,Susi,mndrk: rpm -vvv -i mpg123.rpm
deb: or apt-get install mpg123
piperead~ object:
http://loopool.live.fm
http://loopool.live.fm/filez/pd/
get ext13
pipewrite~:
a) ext13 has a pipewrite~ and even help patch
b) get an old version of ggext ( <= 0.15, after which the sfwrite~ code changed)
http://gige.xdv.org
ftp://xdv.org/pub/gige/ggext/
use sfwrite~ from this version
d) or get:
http://barely.a.live.fm/pd/pipewrite/
probably buggy and approx. 0 support
use pipewrite~
pd:
http://www.crca.ucsd.edu/~msp/software.html
http://iem.kug.ac.at/pd/
deb: (apt-get install pd)
lame:
http://www.mp3dev.org/mp3/
http://lame.sourceforge.net
liveice:
http://star.arm.ac.uk/~spm/software/liveice.html
its also possibly in the icecast distro
deb: (apt-get install liveice)
icecast:
http://www.icecast.org/
deb: (apt-get install icecast-server)
setup:
install all the stuff.
get pd running and the externals, refer to other documentation on how.
get mpg123 running. shouldnt be any prob.
tar zxvf mpg123.tgz
cd mpg123
make linux-help &c
make linux-oss or so ..
make install
get lame running, either.
tar zxvf lame-0.8x.tgz
cd lame
./configure
make
make install
get icecast running. also easy. edit the config file to suit your needs, maybe you only change the passwords.
tar zxvf icecast-1.3.10.tgz
cd icecast
./configure
make
make install
cp /usr/local/icecast/conf/icecast.conf.dist /usr/local/icecast/conf/icecast.conf
jed /usr/local/icecast/conf/icecast.conf
put the passwords, ports,names,locations,limitations as like
the give:
/usr/local/icecast/bin/icecast -c /usr/local/icecast/conf/icecast.conf
add this to your /etc/init.d/ ..
mpg123,liveice,pd and icecast are also avail as debian packages.
lame and the externals isnt ...
now the trickier bits:
get liveice to run. compiling should go slumpi as well.
then make a:
mknod bla p
edit your liveice.cfg, like this:
<SNIP>
# liveice configuration file
# Automatically generated
SERVER localhost
PORT 8000
NAME :et.d,^C8-7_}rS_
GENRE experimental
URL http://my.url.com
PUBLIC 0
X_AUDIOCAST_LOGIN
PASSWORD hackme
SAMPLE_RATE 22050
#MONO
STEREO
NO_SOUNDCARD
HALF_DUPLEX
USE_LAME3 /maybe/full/path/to/which/lame
BITRATE 48000
ENCODING_QUALITY 80
#VBR_QUALITY 1
#MIXER
# slurp.wav is not a real wav file but a pipe as well, made via 'mknod slurp.wav p'
# its just what i call it instead of bla. your choice here.
MIXER_CMD /bin/cat /spz/A/pd/slurp.wav
PLAYLIST playlist
DECODER_COMMAND mpg123
MIX_CONTROL_MANUAL
CONTROL_FILE mix_command
TRACK_LOGFILE track.log
</SNIP>
edit all the rates, sample,bits,quality etc ...
then start liveice whith the following commandline:
/usr/bin/liveice -@ 0 -F liveice.cfg 2>liveice_error.log
redirect stder to the log is necessary so the erroutput doesnt fukc your interface.
you can also go interfaceless with -@ 1 or so ..
(if it doesnt work rightaway its a good idea to look int liveice_error.log and see what it says there.
anbother good thing 4 debugging is to do a
telnet localhost 8000
Trying localhost...
Connected to localhost.
Escape character is '^]'.
ADMIN hackme
OK
-> oper hackme
You are now an icecast operator
> tail
Now tailing logfile
>
notice the two times return after the ADMIN statement. after you said tail, you should see
wether liveice actually connect to the server etc etc)
anyhowm you start it, and then it does nothing (well, you should see it connect in the icecast tail),
but instead waits for the pipe-file to fill.
this will only fill when you open your pd, put the pipewrite~ object, say ; dsp 1;, send
| open bla | to the pipewrite~ objekto, send '1' into pipewrite~ so it starts pipewriting,
and then yeah, connect some osc~ to pipewrite
and you should see the levels jump to a steady state (or not so steady if yaou send toher than plain osc~ output)
in the liveice interface in the neighbouring window.
maybe give absolute path to open message to avoid further confusion .
oke, that's the output bit.
niput: (stream)
put a 'piperead~ 2 1024' object in your patcher window.
consult the piperead~ helppatcher for details.
in short, make another pipe, lets say mkfifo /tmp/xyz
send open /tmp/xyz, send '1' into piperead so it starts reading.
now say
mpg123 -s http://bli.bla.blo:8000/mystreami.mp3
from another terminal ..
youckidoo, there you are.
connect piperead~ to pipewrite~ and its MP3-PD-MP3-ultramultilation.
well, not mutilation yet.
so, place your preferred mutilation rout!n in between and youre set.

NOTES:
======
..............................
using ggext, replace m_pd.h with the one from the PD source tree
if you are using a newer ggext, by some sweet coincidence, the
directory name changed after version 0.15, so having both
libraries installed is very easy.
i think pipewrite~ is shorthand for sfwrite~ or have i missed
something?
-> see above
LAME:
i removed the gtk stuff as per the install file because something
was missing in its internals
a newer liveice is needed, to use the MIXER_CMD directive

there seems to be an error in file setup.c, where g_conf.stereo
is set to 1 or 2 depending upon the number of channels,
where it should be set to 0 or 1 depending upon the truth of
stereo-ness. i.e.:
} else if(!strcmp(cmd,"MONO")) {
g_conf.stereo=0;
} else if(!strcmp(cmd,"STEREO")) {
g_conf.stereo=1;
