--------------------------------
Finally, after several headache i found a workaround.
The idea was to play with the queue only.
set("log.file",true)
set("log.level",3)
set("log.file.path","/home/radio/log/test.log")
set("server.telnet",true)
nbtrack = interactive.float("nbtrack",0.)
def Titre() =
result = get_process_output("php /var/www/titre.php")
request.create(result)
end
def Jingle() =
result = get_process_output("php /var/www/jingle.php")
request.create(result)
end
def crossfade(~conservative=true,s)
s = fade.in(duration=5.,s)
s = fade.out(duration=5.,s)
fader = fun (a,b) -> add(normalize=false,[b,a])
cross(conservative=conservative,duration=3.,fader,s)
end
flux = request.queue(id="titrequeue",interactive=true,queue=[Titre()])
def AddTitre(m)
cnt = nbtrack() + 1.
if cnt > 5. then
ignore(server.execute("var.set nbtrack = 0."))
result = get_process_output("php /var/www/jingle.php")
ignore(server.execute("#{source.id(flux)}.push #{result}"))
else
ignore(server.execute("var.set nbtrack = #{cnt}"))
result = get_process_output("php /var/www/titre.php")
ignore(server.execute("#{source.id(flux)}.push #{result}"))
end
log(label="ON TRACK",level=3,"Track count #{cnt}")
end
flux = on_track(AddTitre(), flux)
flux = crossfade(flux)
flux = fallback(track_sensitive=false,[flux,blank()])
output.icecast(%mp3, host="127.0.0.1", port=8000, mount="/", protocol="icy",
encoding="ISO-8859-1", user="source", password="password", flux)
