a quick example using liquidsoap

connects to a remote shoutcast server and transcodes to aac and mp3 and rebroadcasts to multiple shoutcast servers.

shoutast based sources (djs) connect, switching from the remote source to the live source immediately, and back on disconnect

code:


#!/usr/bin/liquidsoap



# set full path to logfile

set("log.file.path","/var/log/liquidsoap/radiostation.log")



# enable daemon mode

set("init.daemon",true)



# change to run under a custom user/group

set("init.daemon.change_user",true)

set("init.daemon.change_user.group","username")

set("init.daemon.change_user.user","groupname")



# do not create a pid file

set("init.daemon.pidfile",false)



# ip to listen on for djs and sources

set("harbor.bind_addr","127.0.0.1")



# remote source to be transcoded

url = "http://www.remotehost.com:8000"

relay = mksafe(input.http(url))



# port and pass for djs

live = input.harbor("/",port=8000,password="djpassword")



# local file

emergency = single("/path/to/some/lastresort.mp3")



# fallback function

radio = fallback(track_sensitive=false,[live,relay,emergency])



# output to shoutcast servers

output.shoutcast(%mp3(bitrate=256,samplerate=44100,stereo=true),name="Radio Station",genre="Genre",host="127.0.0.1",port = 8000,password = "changeme",radio)

output.shoutcast(%mp3(bitrate=128,samplerate=44100,stereo=true),name="Radio Station",genre="Genre",host="127.0.0.1",port = 8010,password = "changeme",radio)

output.shoutcast(%mp3(bitrate=64,samplerate=44100,stereo=true),name="Radio Station",genre="Genre",host="127.0.0.1",port = 8020,password = "changeme",radio)

output.shoutcast(%mp3(bitrate=24,samplerate=22050,stereo=false),name="Radio Station",genre="Genre",host="127.0.0.1",port = 8030,password = "changeme",radio)

output.shoutcast(%aac(bitrate=256),name="Radio Station",genre="Genre",host="127.0.0.1",port = 8000,password = "changeme",radio)

output.shoutcast(%aac(bitrate=128),name="Radio Station",genre="Genre",host="127.0.0.1",port = 8010,password = "changeme",radio)

output.shoutcast(%aac(bitrate=64),name="Radio Station",genre="Genre",host="127.0.0.1",port = 8020,password = "changeme",radio)

output.shoutcast(%aac(bitrate=24),name="Radio Station",genre="Genre",host="127.0.0.1",port = 8030,password = "changeme",radio)

this can be easily modified to just play a directory of media and perform the same live dj switching:

code:


#!/usr/bin/liquidsoap



# set full path to logfile

set("log.file.path","/var/log/liquidsoap/radiostation.log")



# enable daemon mode

set("init.daemon",true)



# change to run under a custom user/group

set("init.daemon.change_user",true)

set("init.daemon.change_user.group","username")

set("init.daemon.change_user.user","groupname")



# do not create a pid file

set("init.daemon.pidfile",false)



# ip to listen on for djs and sources

set("harbor.bind_addr","127.0.0.1")



# remote source to be transcoded

# A playlist

archives = playlist("/some/directory/of/mp3")



# port and pass for djs

live = input.harbor("/",port=8000,password="djpassword")



# fallback function

radio = mksafe(archives)

radio = fallback(track_sensitive=false,[live,archives])



# output to shoutcast servers

output.shoutcast(%mp3(bitrate=256,samplerate=44100,stereo=true),name="Radio Station",genre="Genre",host="127.0.0.1",port = 8000,password = "changeme",radio)

output.shoutcast(%mp3(bitrate=128,samplerate=44100,stereo=true),name="Radio Station",genre="Genre",host="127.0.0.1",port = 8010,password = "changeme",radio)

output.shoutcast(%mp3(bitrate=64,samplerate=44100,stereo=true),name="Radio Station",genre="Genre",host="127.0.0.1",port = 8020,password = "changeme",radio)

output.shoutcast(%mp3(bitrate=24,samplerate=22050,stereo=false),name="Radio Station",genre="Genre",host="127.0.0.1",port = 8030,password = "changeme",radio)

output.shoutcast(%aac(bitrate=256),name="Radio Station",genre="Genre",host="127.0.0.1",port = 8000,password = "changeme",radio)

output.shoutcast(%aac(bitrate=128),name="Radio Station",genre="Genre",host="127.0.0.1",port = 8010,password = "changeme",radio)

output.shoutcast(%aac(bitrate=64),name="Radio Station",genre="Genre",host="127.0.0.1",port = 8020,password = "changeme",radio)

output.shoutcast(%aac(bitrate=24),name="Radio Station",genre="Genre",host="127.0.0.1",port = 8030,password = "changeme",radio)
