IDJC 0.9.8/0.9.9_development on Linux Mint 21.3: No GUI

[Moonbase]

Hi again!

My main machine broke down, so I tried to (re-)install IDJC on my Linux Mint 21.3 laptop. Building libshout-idjc version 2.4.6 and either IDJC 0.9.8 or 0.9.9_development (from git) succeed, but I don’t ever get a UI.

$ cat /etc/os-release 
NAME="Linux Mint"
VERSION="21.3 (Virginia)"

ID_LIKE="ubuntu debian"
PRETTY_NAME="Linux Mint 21.3"

UBUNTU_CODENAME=jammy

It goes this far, then nothing more happens. IDJC also doesn’t appear in the Carla JACK patchbay.

$ idjc

What can be causing this? Any more info you need?

Note I once had IDJC running on this machine, I believe when it still was Mint 20.x and IDJC 0.8.something. I tried to remove the old installation by doing "sudo make uninstall" and manually checking for remnants left before compiling and installing the new ones. Apparently it took the previous configuration (which is good).

If it helps, some more info from "inxi -Fxxx":

When watching the QjackCtl Graph or the Carla Patchbay closely, upon starting idjc, it shows up very briefly (few seconds), without any connections, then vanishes again.

The termnal output doesn’t change after the line

reply='idjc backend ready\n'

and idjc has to be aborted by pressing Ctrl+C.

Note: Trying to build 0.9.9_development against anything other than "libshout-idjc-2.4.6" (like 2.4.5 or the Icecast libshout 2.4.6) fails because "shout_set_metadata_utf8" is undefined.

More Pipewire ****.

$ sudo apt install pipewire-audio-client-libraries

Then start idjc with...

$ pw-jack idjc

If you now chose to rebuild idjc the build process will generate an extra menu entry that starts idjc under pw-jack.

[Moonbase]

Thanks, will try. No way to just use JACK w/o Pipewire? Don’t really need PW…

[Moonbase]

Rebuilt 0.9.9_dev after installing above, restarted system and tried

$ pw-jack /usr/bin/idjc

To be sure, deleted the old ~/.config/idjc folder and tried again. Now it behaves exactly like idjc without pw-jack:

$ pw-jack /usr/bin/idjc
jack client ID: idjc_default
idjc 0.9.9_development
cpython 3.10.12 (main, Nov 20 2023, 15:14:05) [GCC 11.4.0]
IRC support requires python-irc: not installed

backend launch attempt 1
libshout-idjc version 2.4.6
started 6 encoders, 6 streamers, 2 recorders
player read buffer allocated for 1024 frames
awaiting status message from back-end
reply='idjc backend ready\n'

… and is stuck without UI.

JACK2 itself works nicely, like with Carla, Audacious and other software.

Tried disabling Pipewire using

sudo systemctl disable --global pipewire

Rebooted, Pipewire not running. Rebuilt, same symptoms (plus 2 menu entries).

[Stephen Fairchild]

I have LM21.3 already as a backup OS and after installing libshout-idjc and idjc itself it launched so I have no clue other than for you it appears the back-end is crashing.

[Moonbase]

Any good way to better diagnose this?

Does anyone else use Mint 21.3, does it work, and which version of libshout-idjc are you using?

[Brian Millham]

Do you actually need libshout-idjc? It's now only required for AAC or MP2 streams (with the latest development version.)

[Moonbase]

Maybe not, I did a short try using normal libshout, but I seem to remember there was an error trying to use that. We’re all doing MP3 streams, so this could be an option. Suggestions how I can tackle that?

EDIT: Found it above: "Trying to build 0.9.9_development against anything other than "libshout-idjc-2.4.6" (like 2.4.5 or the Icecast libshout 2.4.6) fails because "shout_set_metadata_utf8" is undefined."

I really wish we could solve these "building hurdles", so IDJC could re-appear in the distros.. IDJC is one of the best and at the same time most under-represented pieces of software I know of. I mean, I have around 20 friends keeping their Linux Mint at 19.3 just because we got a working IDJC on that! Shows how important this wonderful piece of software is to them…

[Stephen Fairchild]

Are you saying libshout 2.4.6 installed from source does not work with idjc? Did you run ldconfig afterwards? Did you do ./configure --prefix=/usr in other words basically follow the same script as you would for libshout-idjc?

The next Linux Mint (version 22) will be based on a version of Ubuntu that comes with libshout-2.4.6. Expect it to arrive this Summer.
