I was trying to insert metadata on stream
(https://github.com/savonet/liquidsoap/issues/570) and it worked, but now I
tried it in my real radio script and its not working.
The main differences are that the input now is a continuous stream from 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",

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