Il est possible de demander au serveur Linux de streamer tous les mp3 et d’envoyer le flux à une radio SHOUTCast

Pour un élément mieux maintenu, je vous conseille LiquidSoap !

Si vous exécutez un Ubuntu 64 bits, il faut installer les librairies 32 bits

apt-get -y install lib32ncurses5

Passons aux choses sérieuses :

On récupère les fichiers 32bits

wget http://bdd.exolia.fr/shoutcast/sc_trans_posix_040.tgz

On créé le dossier qui va bien

mkdir /opt/shoutcast/transcode

On extrait les données de l’archive

tar zxvf sc_trans_posix_040.tgz

On déplace

mv sc_trans_040 /opt/shoutcast/transcode

On créé le fichier de configuration

nano /opt/transcode/server.conf

Avec en contenu du fichier

; sc_trans accepts the following signals:
; HUP - flush logfiles (close and reopen) -- will make console logging stop
; WINCH - jump to next song
; USR1 - reload playlist off disk (will not interrupt current playing stream)
; USR2 - toggle shuffle on/off
; TERM - normal sc_trans shutdown (clean)

; PlaylistFile (required EVEN IF RELAYING) - playlist file (to create, use
; find /home/mp3/ -type f -name "*.mp3" > /opt/shoutcast/transcode/playlist.lst
PlaylistFile=/opt/shoutcast/transcode/playlist.lst

; ServerIP/ServerPort are the target server to send to
ServerIP=127.0.0.1
ServerPort=8000

; Password is the password on the sc_serv you're sending to.
Password=password

; StreamTitle/URL/Genre define the data that appears on the directory and in the
; stream info.
StreamTitle=_Nom Radio_
StreamURL=http://_votre_serveur_
Genre=mix

; Logfile optionally denotes a text file to log sc_trans to.  a kill -HUP
; will force a close and re-open of this file (but will also cease logging to
; the console)
LogFile=sc_trans.log

; Shuffle the playlist
Shuffle=1

; Bitrate/SampleRate/Channels recommended values:
; 8kbps 8000/11025/1
; 16kbps 16000/11025/1
; 24kbps 24000/22050/1
; 32kbps 32000/22050/1
; 64kbps mono 64000/44100/1
; 64kbps stereo 64000/22050/2
; 96kbps stereo 96000/44100/2
; 128kbps stere0 128000/44100/2
Bitrate=64000
SampleRate=22050
Channels=2

; Quality is from 1-10. 1 is best, 10 is fastest.
Quality=1

; Mode=0 for none, 1 for 100/100->100/0, 2 for 0/100->100/0
CrossfadeMode=1

; Length is ms.
CrossfadeLength=5000

UseID3=0

; Public determines whether or not this station will show up in the directory
Public=1

On créé le daemon

On le rend exécutable et on initialise le script

chmod +x transcode.sh
update-rc.d transcode.sh defaults

On exécute le service

/etc/init.d/transcode.sh start

On peut contrôler que le service est opérationnel

ps aux | grep "sc_trans"
