Liquidsoap for Icecast AutoDJ doesn't work

[Jonikster]

Hello.
There is an IceCast server. It works correct.
I want to configure AutoDJ on the Linux server to play tracks from the / Home / Music folder.
So, I tried Liquidsoap. But it doesn't work.
So what did I do?
I have Debian 10.9.0.

apt install icecast2

In the .xml file I created MountPoints:

<mount>
 <mount-name>/autodj</mount-name> 
 <password>test123</password> 
 <max-listeners>500</max-listeners> 
 <max-listener-duration>3600</max-listener-duration> 
 <dump-file>/tmp/dump-live.mp3</dump-file> 
 <intro></intro>

 <public>1</public> 
 <stream-name>TestRadio</stream-name>

 <subtype>mp3</subtype>

 <mp3-metadata-interval>4096</mp3-metadata-interval> 
</mount>

I used different ways to install Liquidsoap. With apt install Liquidsoap, opam and deb package.
It didn't run, so I used the template:
https://github.com/Renaud11232/icecast-autodj

git clone https://github.com/Renaud11232/icecast-autodj.git
cd icecast-autodj
mkdir -p /etc/liquidsoap
cp configs/dj.liq /etc/liquidsoap
chown -R icecast2:icecast /etc/liquidsoap
chmod 660 /etc/liquidsoap/dj.liq
cp systemd/liquidsoap.service /etc/systemd/system/
systemctl daemon-reload
systemctl enable icecast2
systemctl enable liquidsoap
systemctl start icecast2
systemctl start liquidsoap

dj.liq:

#set("init.daemon.pidfile",false)

def update_title(m) =
 title = m["title"]
 if title == "" or title == "Unknown" then
  content = m["filename"]
  content = basename(content)
  content = get_process_output("STR=\""^content^"\"; echo ${STR%.*}")
  content = string.recode(out_enc="UTF-8", content)
  [("title", content)]
 else
  sArtist = string.recode(out_enc="UTF-8", m["artist"])
  sTitle = string.recode(out_enc="UTF-8", m["title"])
  [("title", sTitle),
  ("artist", sArtist)]
 end
end
set("tag.encodings",["UTF-8"])
music = nrj(playlist(mode='randomize', reload_mode='rounds=1', '/home/music'))
mount = "autodj",
encoding = "ISO-8859-1",
default,
host = "ip", port = 8000, password = "test123",
genre="other",
name="TestRadio",
fallible = true,
icy_metadata="true",
public=true,
url="http://ip",
description="It's TestRadio!")

But, after executing systemctl start, I open http://ip:8000/autodj, and it doesn't work.
What's wrong? Please help me!
Thank you in advance!

Is there any chance you could format the code and xml parts of your post by editing them, selecting the appropriate parts and using the <> (code) formatter in the editor toolbar, it's almost impossible to read as it is at the moment.

[jonathanstowe]

Also, while testing a new script it might be better to add

set("log.file", false)
set("log.stdout", true)

To the top of the script and then run liquidsoap in the foreground like:

liquidsoap script.liq

rather than as a daemon so you can see if there are any problems with your script.

[jonathanstowe]

Hi,
there were a couple of problems with the script: firstly the basename at line 17 should be path.basename and secondly it appears to omit part of the output.icecast call at around line 30. If adjusted as:

#!/usr/bin/liquidsoap -d
#set("init.daemon",true)
#set("init.daemon.pidfile",false)
set("log.file",false)
#set("log.file.path","/var/log/liquidsoap/basic.log")
set("log.stdout",true)
set("log.level",4)
set("decoder.file_decoders",["META","MAD","OGG"])
set("decoder.file_extensions.mad",["mp3","mp2","mp1"])
set("decoder.file_extensions.ogg",["ogv","oga","ogx","ogg","opus"])
set("decoder.mime_types.ogg",["application/ogg","application/x-ogg","audio/x-ogg","audio/ogg","video/ogg"])
set("decoder.mime_types.mp3",["audio/mpeg","audio/MPA"])
def update_title(m) =
 title = m["title"]
 if title == "" or title == "Unknown" then
  content = m["filename"]
  content = path.basename(content)
  content = get_process_output("STR=\""^content^"\"; echo ${STR%.*}")
  content = string.recode(out_enc="UTF-8", content)
  [("title", content)]
 else
  sArtist = string.recode(out_enc="UTF-8", m["artist"])
  sTitle = string.recode(out_enc="UTF-8", m["title"])
  [("title", sTitle),
  ("artist", sArtist)]
 end
end
set("tag.encodings",["UTF-8"])
music = nrj(playlist(mode='randomize', reload_mode='rounds=1', '/home/jonathan/Music'))
output.icecast(
  %mp3(
    bitrate=160
  ),
mount = "autodj",
encoding = "ISO-8859-1",
music,
host = "127.0.0.1", port = 8000, password = "hackme",
genre="other",
name="TestRadio",
fallible = true,
icy_metadata="true",
public=true,
url="http://localhost",
description="It's TestRadio!")

(host, password and playlist path being adjusted as per my local setup.)

And that all works fine:

I can't recommend running the script in the foreground with logging to stdout turned on before attempting to run as a daemon with no logging enough, it would show exactly where the problems are.
