OP25 liquidsoap not working

[VengeanceNight]

Hi...I've been working on this for a while and have had no luck. I'm someone who likes to try and read everything available and figure it out on my own but haven't been able to this time.

I was able to get op25 working with local audio and was working on enabling remote audio using icecast. I believe the issue is with not calling liquidsoap correctly and hoping I'm just missing something obvious.

I am using multi_rx.py. I am able to connect to the icecast2 admin page but get no status and no active mountpoints are shown. Looking at the icecast log I see the following error:

/usr/share/icecast2/web/mount
WARN admin/admin_handle_request Admin command metadata on non-existent source /mount

It does look like liquidsoap is running as when checking the version I get

Liquidsoap 2.2.4-1+dev
Copyright (c) 2003-2023 Savonet team
Liquidsoap is open-source software, released under GNU General Public License.
See <Liquidsoap - Audio & Video Streaming Language> for more information.

I check the liquidsoap log directory and it's empty. So that is why I think I may not be calling it

Here are the relevant sections from the config file.

"metadata": {
        "module": "icemeta.py",
        "streams": [
            {
                "stream_name": "stream_0",
                "meta_format_idle": "[idle]",
                "meta_format_tgid": "[%TGID%]",
                "meta_format_tag":  "[%TGID%] %TAG%",
                "icecastServerAddress": "192.168.1.1:8000",
                "icecastMountpoint": "mount",
                "icecastMountExt": ".m3u",
                "icecastPass": "password",
                "delay": 0.0
            }
        ]
    },
    "audio": {
        "module": "",
        "instances": [
            {
                "instance_name": "audio0",
                "device_name": "default",
                "udp_port": 23456,
                "audio_gain": 1.0,
                "number_channels": 1
            }
        ]
   },

Any help would be appreciate. Just let me know if you want me to post any more information. Thanks!

The channel destination of your multi_rx.py JSON must point to the port that Liquidsoap's input operator is listening on.
Liquidsoap's output.icecast operator must be configured to the desired IP address, port, mountpoint and password of
the intended Icecast server.

Example multi_rx.py channel
"destination": "udp://127.0.0.1:23450",

Example op25.liq Version 1.4.3 input operator()
input = input.external.rawaudio(buffer=0.25, channels=2, samplerate=8000, restart_on_error=false, "./audio.py -u 23450 -x 1.25 -s")

Example op25.liq Version 1.4.3 output.icecast operator()
output.icecast(%mp3(bitrate=16, samplerate=22050, stereo=false), description="op25", genre="Public Safety",
url="", fallible=false, icy_metadata="false", host="localhost", port=8000, mount="op25", password="hackme", mean(input_safe))

Thank you for responding! I did not have -u 23450 added to my input in the op25.liq file. Thought that was the answer but added it in and still have the same issue.

Are you running Icecast on the same machine as op25? If so, enable logging to level-3 in Liquidsoap and capture all of the data that scrolls
when first starting it up, then post here for further analysis.

I am but as far as I can tell there aren't any logs being generated. Here are my settings for enabling the logs

set("log.stdout", true)
set("log.file", true)
set("log.level", 3)

I'm checking for the log in /var/log/liquidsoap

Thanks for your help

Suggest setting up logging to a folder owned by your account such as the op25 apps folder for example.

IE: set("log.file.path", "/home/login_user_name/op25/op25/gr-op25_repeater/apps/liquidsoap.log")

Made the update and am still not seeing a log file generated. Here is my op25.liq file in case it is helpful

# Example liquidsoap streaming from op25 to icecast

# Make the native sample rate compatible with op25
set("frame.audio.samplerate", 8000)

input = mksafe(input.external(buffer=0.25, channels=2, samplerate=8000, restart_on_error=false, "./audio.py -x 1.5 -s"))
# Consider increasing the buffer value on slow systems such as RPi3. e.g. buffer=0.25
# Longer buffer results in less choppy audio but at the expense of increased latency.

# Compression

Here is also the section in icecast.xml with the hostname and listen-socket

<!-- This is the hostname other people will use to connect to your server.
         It affects mainly the urls generated by Icecast for playlists and yp
         listings. You MUST configure it properly for YP listings to work!
    -->
    <hostname>localhost</hostname>

    <!-- You may have multiple <listen-socket> elements -->
    <listen-socket>
        <port>8000</port>
        <bind-address>192.168.1.1</bind-address> -->
        <shoutcast-mount>op25</shoutcast-mount> -->
    </listen-socket>

Thanks again for all the help

I am not clear how you're executing Liquidsoap. Here's an example of execution from the command line that assumes you've made
op25.liq executable. Note that you'll see the log data scroll in your terminal as you execute op25.liq.
