Hi,
I've finally got a script that works, and plays everything in order with
smart_crossfades.
One problem has surfaced: OGGs without an ID3 Tag.
The title for each of the OGGs is essentially its filename. So, while
searching for a way
to have something in the player's info box rather than 'Unknown', I came
upon David Baelde's
solution of 'def fill_in(s)'.
It has worked once or twice in some earlier attempts at getting my
'liquidsoap.liq' to work.
In this working liq, it doesn't seem to function. At this point I don't
know exactly where I
should put this function. Obviously, where I have it is not the right
spot. :)
Checking the log, the function isn't mentioned, so, I suppose that's good.
It's
not broken, but perhaps it isn't even activated because of an error on my
part.
Here's the liquidsoap.liq:
****
#!/usr/local/bin/liquidsoap
# === SETTINGS ===
set("log.file.path","/usr/local/var/log/liquidsoap/liquidsoap.log")
set("init.daemon.pidfile.path", "/var/run/liquidsoap/liquidsoap.pid")
# === Load OGG Section ===
# security = single("usr/local/www/rcr/ogg/fallback/Welcome.ogg")
# === ID TO APPLY to SWITCH SCHEDULE ===
a = single("/usr/local/www/rcr/ogg/announce/SOD.ogg")
b =
single("/usr/local/www/rcr/ogg/announce/opener/opener-sstol.ogg")
c = playlist.safe(mode="normal",
"/usr/local/www/rcr/radio/current/ogg/today-sstol-ogg-32.pls")
d = playlist.safe(mode="normal",
"/usr/local/www/rcr/radio/current/ogg/sstol-ogg-end-32.pls")
e = single("/usr/local/www/rcr/ogg/announce/CLOSER.ogg")
# a = audio_to_stereo(a) [doesn't seem to be needed now]
sstol = sequence([a,b,c,d,e])
# Fill-in Title for ID3 Tag
def fill_in(s)
# the function f takes a list of pairs m representing the
metadata
# and it maps an anonymous function on each pair
# replacing empty title definitions by title=filename
def f(m)
list.map(fun (key_value) ->
if key_value==("title","") then
("title",m["filename"]) else
key_value end,
m)
end
map_metadata(f,s)
end
# Then just wrap your source at an appropriate spot:
# source = fill_in(source)
icogg = fill_in(sstol)
icogg = smart_crossfade(start_next=0.4, fade_in=0.2, fade_out=0.2,
conservative=true, a)
# == ICECAST OGG OUTPUT ==
output.icecast.vorbis(quality=0.8,samplerate=22050,stereo=false,
host="xxx.xxx.xxx.xxx",
port=8000,
password="******",
mount="icogg.ogg",
name="",
description="",
genre="",
url="",
icogg)
****
Thanks,
Andre
