Hi, it worked with that test script, but now I tried it in my real radio script
and its not working.
The main differences are that the input is jackd application and the output
formats are .opus and .mp3. The .liq script works ok but no metadata is shown
when playing the stream.
Script I'm running:
set("log.stdout",true)
set("log.file.append",true)
set("log.level", 4)
set("log.file.path","/home/radiola/liquidsoap.log")
set("frame.audio.samplerate",48000)
#Update Title function
def append_title(m) =
newtitle = list.hd(
get_process_lines(
"sudo mysql mydatabase -u root -phackme -se \"SELECT CAST(CONVERT(Title
USING utf8) AS binary) FROM mytable WHERE id='1'\""
)
)
[("title","#{newtitle}")]
end
#Update artist function
def append_artist(m) =
newartist = list.hd(
get_process_lines(
"sudo mysql mydatabase -u root -phackme -se \"SELECT CAST(CONVERT(Artist
USING utf8) AS binary) FROM mytable WHERE id='1'\""
)
)
[("artist","#{newartist}")]
end
#Source stream comes from jackd
s = input.jack()
#Insert metadata on stream:
s = map_metadata(append_title, s)
s = map_metadata(append_artist, s)
output.icecast(%opus(
vbr="constrained",
complexity=10,
max_bandwidth="full_band",
samplerate=48000,
bitrate=128,
channels=2,
),
host="localhost",
port=8000,
password="hackme",
mount="aovivo.opus",
s
)
output.icecast(%mp3.cbr(
bitrate=128,
samplerate=48000
),
host="localhost",
port=8000,
password="hackme",
mount="aovivo.mp3",

Would an input from jackd trigger the function that updates metadata at all?
And do opus and mp3 support this way of inserting metadata?
