MP3-PD-MP3_mutilation

what u need:

mpg123 (http://www.mpg123.de/)
	standard on many distributions


piperead~ object:
        http://loopool.live.fm
        http://loopool.live.fm/filez/pd/
        get ext13


pipewrite~:
        get an old version of ggext ( <= 0.15, after which the sfwrite~ code changed)
        http://gige.xdv.org
        ftp://xdv.org/pub/gige/ggext/

        or get:
        http://barely.a.live.fm/pd/pipewrite/ 
        probably buggy and approx. 0 support


pd:
	http://www.crca.ucsd.edu/~msp/software.html
	http://iem.kug.ac.at/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


icecast:
	http://www.icecast.org/


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.
