I rip all of my CDs as aac/mp4/m4a files so they can be loaded on the iPod.  But icecast/icegenerator serves mp3 files (I could use [http://developer.apple.com/opensource/ Darwin] to serve aac files presumably).  Here is the script for finding and ripping all m4a files into mp3 files in a subdir called mp3:
 +
 +
<pre>
 +
#! /usr/bin/perl -w
 +
use File::List;
 +
 +
# find all dirs
 +
@dirs = `find -type "d"`;
 +
#print "@dirs";
 +
 +
# for each dir
 +
foreach $d (@dirs){
 +
  chomp $d;
 +
  #print "$d\n";

  ## skip the top level

On gismo:

Starting icecast

to start icecast, as root: 

  su - iceuser
  cd /usr/local/icecast2
  icecast -c icecast.xml &
  exit

Loading playlists

playlists can be obtained as m3u files, which simply give the path to mp3 files, e.g., 

/home/phurvitz/phmusic/e/evoria/EvoriaCesaria_Untitled - 03-17-03_03 carnaval de sao vicente.mp3

or read from the contents of a directory, recursively.

to load a playlist, as phurvitz: 

  icegenerator -f /home/phurvitz/icecast/icegenerator.conf.3
(or whatever icegenerator file)


Icegenerator configuration files

The configuration files let icegenerator know what/how to serve audio files. Examples:

the icegenerator file reading from an m3u file:

      # tally mp3 files
      @mp3s = `ls \"$d\"/*.mp3 2>/dev/null`;
      $mp3count = @mp3s;

      ## if dir contains m4a files

          $mp3dir = join('/', $d, "mp3");
          if (! -e "$mp3dir") {
              print "making \"$mp3dir\" \n";
              system "mkdir \"$mp3dir\"";
          }

          # if the mp3dir exists then move mp3s there
          if (-e "$mp3dir") {
            if ($mp3count > 0) {
