Hi Romain,
I updated to Liquidsoap 1.3.3 using opam and now it won't compile my script.
FIrst I had to change the way I call "imeta()" to:
imeta([("title",#{new_title}), ("artist",#{new_artist})])
But now it's still accusing a "parse error" at the end of the definition of
function "update_meta".
Line 37, char 4 before "end": Parse error!
Did it change the way functions should be defined in this version? Im using:
def update_meta() =
...
...
5.0
end

Hi Bruno,
Your script looks good and the logs seem to indicate a clear bug in the
software. However, 1.1.1 is a rather old version. Would you be able to test it
with version 1.3.3? I'm happy to provide instructions on how to update
liquidsoap.

Hello, I need to get title and artist metadata from MySQL table and update it
on stream every 5 seconds.
I wrote a script that did this based on earlier responses here but for some
reason the "update_meta()" function that should be executed every 5 seconds is
only being execute twice and then stops.
Seems to be a problem somewhere.. Any help is apreciated. The script is as
follows:
#!/usr/local/bin/liquidsoap
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)
s = input.jack()
# Create a function to insert metadata
ms = insert_metadata(s)
# The function to insert metadata
imeta = fst(ms)
# The source with inserted metadata
s = snd(ms)
# Function that updates metadata
def update_meta() =
# Gets title from MySQL table and stores in variable
new_title = list.hd(
get_process_lines(
"mysql my_db -u root -phackme -se \"SELECT CAST(CONVERT(Title USING utf8)
AS binary) FROM song WHERE id='1'\""
)
)
# Gets artist from MySQL table and stores in variable
new_artist = list.hd(
get_process_lines(
"mysql my_db -u root -phackme -se \"SELECT CAST(CONVERT(Artist USING utf8)
AS binary) FROM song WHERE id='1'\""
)
)
#A debug message
print("Insert metadata title = #{new_title}")
print("Insert metadata artist = #{new_artist}")
# Insert the metadata
imeta([("title",new_title),("artist",new_artist)])
5.0
end
# Schedule the insert metadata process every 5.0 seconds
add_timeout(fast=false,5.0,update_meta)
# MountPoint = st1.opus\group=transmitter
output.icecast.......
# MountPoint = aovivo.opus
output.icecast.......
# MountPoint = aovivo.mp3
output.icecast.......
# MountPoint = stream
output.icecast.......
# MountPoint = transmitter.mp3
output.icecast.......
As you can see I put a debug message to be printed when the update_meta
function is executed and the message appears only twice when executing the
script.. The log is as follows:
