Hello Romain,
Here is the script
----
#!/usr/local/bin/liquidsoap
set("scheduler.log",false)
set("log.level", 3)
fluxid = argv(1)
name = argv(2)
description = argv(3)
finaldesc = string.replace(pattern="_",(fun (s) -> " "),description)
genre = argv(4)
mountpoint = "flux-"^fluxid
cmd = "/radionomy/getsoundtoplay.php "^fluxid
input = request.dynamic(id=fluxid, fun () -> request(get_process_output(cmd)),
conservative=true)
def our_crossfade(~start_next,~fade_in,~fade_out,s)
s = fade.in(duration=fade_in,s)
s = fade.out(duration=fade_out,s)
fader = fun (a,b) -> add(normalize=false,[b,a])
cross(conservative=true,duration=start_next,minimum = -1.0,fader, s)
end
input2=our_crossfade(start_next=6.0,fade_in=3.0,fade_out=3.0, input)
input2 = nrj(input2)
input2 = rewrite_metadata([("artist",'$(if
$(display_artist),"$(display_artist)","$(artist)")'),("title", '$(if
$(display_title),"$(display_title)","$(title)")'),("album", '$(if
$(display_id),"$(display_id)","$(album)")')],input2)
input2 = on_metadata(fun (meta) -> system("curl
http://dummy.radionomy.com/dummy.php?string="^fluxid^","^quote(meta["album"])^"
&"),input2)
output.icecast.mp3(mount=mountpoint, host="localhost", port=1234,
password="dummy", genre=""^genre, url="http://www.radionomy.com";,
name=""^name,description = ""^finaldesc, mksafe(input2))

Concerning the test, I can test a new 'stable' version in production (our test
environment is not powerfull enough to manage a so huge amount of simultaneous
play).
Sounds we give to liquidsoap are all in the MP3 format (but a lot of them are
encoded higher than 128 kbps).
TIA,
Jef

Throughout its 18-year history, RSA Conference consistently attracts the
world's best and brightest in the field, creating opportunities for Conference
attendees to learn about information security's most important issues through
interactions with peers, luminaries and emerging and established companies.
