Romain,
Well to put it simple enough...
You gave us a way to feed tracks into liquidsoap dynamically. Liquidsoap is
doubling up on the request.create as its next song (instantly when it loads the
song). First, can you explain to me how I'm supposed to comfortably feed songs
to liquidsoap when its playing each one two times? Is there a way to pass a
Playlist... or perhaps 2 songs at once, so that gives me till the current song
ends to get new returned when request.create calls on the script.
Basically:
Request.create receives the MP3.
Liquidsoap says, ok I'll load this, and Oh since I see this is the main
fallback for receiving music, I'll go ahead and load it again! Now I have two
of the same track ready to play (...)..
I just need to know how to tell Liquidsoap what to load. I don't know SH
programming, I'm actually a pure PHP programmer. But it's a real mystery here
what your software wants to receive, and how it should be received. It's been a
guessing game.
Once I can dynamically talk to liquidsoap using the request.create (without
every request being a duplicate, and without liquidsoap needing a new fallback
to facilitate it during this dynamic method), I'll add a fallback playlist
later. Right now I'm focusing on how to have full control over liquidsoap using
request.dynamic, so I can begin writing a scheduler in PHP.
Here's the script so far:
#set("init.daemon", true)
set("log.file.path", "nfm.log")
set("server.telnet",true)
def request () =
request.create(audio=true,
list.hd(get_process_lines("/home/nocturnal/track.sh")))
end
def fade(jingles,s)
fade_in = 12.
fade_out = 10.
start_next = 3.
def fader(from,to)
from = fade.out(duration=fade_out,from)
to = fade.in(duration=fade_in,to)
add(normalize=false,
[ to,
sequence([ jingles, fallback([]) ]),
from ])
end
cross(duration=start_next,fader,s)
end
live = input.http(id="live", buffer=10.,
autostart=false, "http://localhost:8000/live";)
live = insert_metadata(id="livemeta",clear_metadata(live))
live = strip_blank(length=10.,live)
# Transitions & Jingle
jingle = normalize( single
("/home/nocturnal/tunes/JINGLE/NFM-Jingle-20090904.mp3") )
# Fallbacks
radio = fallback(track_sensitive = false, [request.dynamic(request),
blank()])
# Add Jingle
radio = fade(jingle,radio)
# Outputs
output.icecast.vorbis (
*****,
radio)

Heh.. The problem, I guess is that you have never written a script so far, have
you ? :-)
The problem that you will run into now is that you need to consider all that
you want
for your system. By that I mean write down exactly the specifications that you
want
for the songs to be played.
Then, you will need to implement them, which means choose a language and write
a
program that finds the correct song according to the specifications.
However, this should not be too difficult. I could try to help. Could you
please try to
write what exactly you want to do for selecting a new song. Try to answer as
simply
as possible to the question:
"Hey, I am liquidsoap. I need to queue a new song, which file should I add ?"
:-)

Well, you can do exactly the same !
In the code you show, playlist is a variable, so it could be named anything
else.
For instance:
s = request.dynamic(...)
s = rewrite_metadata(
[("artist",("[Nocturnal.FM Main] "^" $(artist)")),
("title",("$(title) "^" [The best trance &
progressive] "^" $(album) ")),
("album","")], s)
Here I have replace "playlist" by "s", but you could also use any variable name
that you like..
