OK, here is something that works for me. Try running it unchanged and see
if it works for you as is. If it does, try adding requests as late in the
script as possible. Try and only add requests after the dummystream is
defined so that there will be no requests affecting the dummystream.
#!/usr/bin/liquidsoap
# here is what I have cobbled together that works in the absence
# of requests.
# Try adding requests near the end of you game.
# define transitions to and from stream
default_dj_fade = ref 0.
def to_break(a,b) =
log("transition TO_BREAK called...")
source.skip(b)
add(normalize=false,
[ sequence([ blank(duration=0.01),
fade.initial(duration=!default_dj_fade, b) ]),
a ])
end
def to_stream(a,b) =
log("transition TO_STREAM called...")
add(normalize=false,
[ sequence([ blank(duration=0.01),
b ]),
fade.final(duration=!default_dj_fade, a) ])
end
# set up for metadata switching
breakz = ref ["COOLZ"]
#specify the icecast stream as an input
stream = input.http("http://192.184.9.158:8240/stream";)
#specify the fail over file (could change this to be a template or
directory of files)
failover = mksafe(single("/var/audio/emergency/BahamianMix1.mp3"))
def f(x) =
(snd(x))
end
def on_meta (meta)
breakz := list.map(f,meta)
print (!breakz)
end
stream = on_metadata(on_meta, stream)
radiostream = stream
#Specify what to switch to when silence is detected
radiostream = fallback(track_sensitive=false, [radiostream, failover])
dummystream = fallback(track_sensitive=false, [stream, failover])
# Output to ALSA (the pi's audio)
#output.alsa(device="hw:1,0", radiostream)
output.alsa(radiostream)
# try this to keep stream checking metadata
output.dummy(dummystream)
