Intro

I was struggling to fit some requirements:

• I ripped all my CDs on the HD attached to the slug
• I wanted my Philips Streamium (which is not UPnP) to be able to play whatever I want
  • Streamium is not UPnP
  • Streamium doesn't understand Ogg format
  • Streamium has a very poor UI
• I wanted to be able to control the playlist from any other computer in the house
• Why not extending those possibilities from anywhere on the Net?

Resources

• madplay/libmad (fixed point mp3 player)
  • In terms of codecs this is the only fixed-point lib available for the slug and it allows only mp3 playback.
• musicdp, aka mpd (its faq)
  • That's THE solution to manage the playlists, now we need to cope with its playing capabilities...
• http://www.nslu2-linux.org/wiki/HowTo/SlugAsAudioPlayer
  • With mpd and libmad, good idea but is using the slug soundcard (if you add one), not icecast
• icecast2
  • The solution for streaming, if we find the right way to add a mp3 source to it.
• mpd + icecast2
  • 2 problems: only streaming in Ogg and needs to reencode the stream, too much without a fixed point encoder!
• oggfwd
  • Would solve one problem: does not reencode, but, as the name tells you, only Ogg.
• EzStream
  • Good candidate, feeds icecast with mp3 without reencoding, but needs to be hooked to mpd
• Ices and especially the versions 0.x
  • Same as for EzStream
• Jinzora
  • To be explored... but requires php/mysql, maybe too much for the slug
• Hack mpd with ices client
  • That's the best I could find: a Perl script as scriptable playlist for ices fetches the songs from mpd playlist ans streams them to icecast2
  • Ices in its basic configuration doesn't perform any reencoding
  • Note that the old version of ices is required as the new one supports only Ogg

Let's go

ices compilation

• Debian features only ices2 so we've to compile the old version ourselves

apt-get install libshout3-dev libperl-dev libmp3-info-perl
wget http://downloads.us.xiph.org/releases/ices/ices-0.4.tar.gz
tar xzf ices-0.4.tar.gz 
cd ices-0.4
./configure --with-perl
make
cp src/ices /usr/local/bin
cp conf/ices.conf.dist /etc/ices.conf

• Copy script from http://mpd.wikia.com/wiki/Hack:ices-client

wget -q -O - http://mpd.wikia.com/wiki/Hack:ices-client%7Cawk '/

/,/<\/pre>/'|html2text -width 200 > mpdplaylist.pm
* ices.conf + edit script
* ./ices
* TODO: 
** default playlist: get songs randomly from playlist file but don't install it in mpd
** next song: killall -s USR1 ices
** how to make it remotely?? through icecast2(php auth?) or mpd... icecast2 mount on-connect -> script: ices user?
** ices crossfade?

===mpd===
* apt-get install mpd mpc
* /etc/mpd.conf
* /etc/init.d/mpd stop
* mpd --create-db
* /etc/init.d/mpd start
* mpc stop
* When need to update the DB: mpc update
===icecast2===
* apt-get install icecast2
* /etc/icecast2/...
* /etc/default/icecast2 -> enabled=true
===TODO===
* setup phpmp2?
* auto upload of ripped CDs?
