LibreElec/Kodi/Tvheadend crashed when clicking a radio channel in Tvheadend client

[kkarsten62]

I already opened a ticket in Kodi forum:
https://forum.kodi.tv/showthread.php?tid=379169&pid=3212900#pid3212900
But people advised me to open the ticket here.

I am using LibreElec/Kodi/Tvheadend on a Intel NUC as server. And Fedora 40 Workstation on my Desktop Computer and on a Tablet as clients.

• Free TV channels via DVB-T2
• Private TV channels via IPTV
• Free Radio channels via IPTV

All TV channels working fine on all three devices (NUC server, Desktop Workstation client, Tablet client)
Radio channels working fine on NUC server
Kodi crashed when a radio channels is clicked on Desktop Workstation client and Tablet client

Entry of a radio channel in iptv.m3u

Here a some logs:

For flatpak debugging I followed
https://docs.flatpak.org/en/latest/debugging.html
flatpak install --include-sdk --include-debug tv.kodi.Kodi
I choose:

1. flathub’ (system)

Then:
flatpak run --command=sh --devel --filesystem=$(pwd) tv.kodi.Kodi
A new sh opened, but I don't know what to do here?!
Stepped out by CTRL-D

Instead:
coredumpctl list
flatpak-coredumpctl -m 14948 tv.kodi.Kodi
(gdb) bt full
See log here:

Thanks for any help.

Kodi crashed when a radio channels is clicked on Desktop Workstation client and Tablet client

Was this a one-time crash or can you reproduce it?

[kkarsten62]

Was this a one-time crash or can you reproduce it?

Yes it can be reproduce.

• On both devices, the Tablet Client and my Desktop Workstation client
• Both with Fedora 40
• Using TVheadend Client, connected to the Intel NUC Hardware installed with Libreelec/Kodi/Tvheadend server
• Tvheadend client installed using Fedora GUI Software/Kodi (Flathub/Flatpak) on the both clients
• Clicking on TV channel on NUC, Desktop, Tablet ==> ok
• Click on radio channel NUC ==> ok
• Click on radio channel on Tablet and Desktop => crash ==> Kodi disappears, Messagebox in Fedora shown up:"Ups! We are sorry, it looks "Kodi.bin" crashed. Please contact the developer if you want to report the issue."

Okay, from looking at the related code i cannot see where it crashes exactly. Would you be able to build the addon yourself so we get debug symbols?

I never did to build a Flatpack/Kodi Addon. But I am developer in C++, Qt, Python3 - so I will do my very best. Please give me some advice where to start.

I will set up on weekend a dedicated VM to build kodi and pvr.hts with debug symbols.

I just checked the debugging options adviced by https://docs.flatpak.org/en/latest/debugging.html#debug-shell.
But what I see this is not really helpful.
I did:
Delete existing Kodi Flatpak via GUI software app

$ flatpak install --include-sdk --include-debug tv.kodi.Kodi
$ flatpak run --command=sh --devel --filesystem=$(pwd) tv.kodi.Kodi

I need a helping hand.

I set up a VM with a fresh Fedora 40 Workstation installation. Crash can be reproduce in this VM.
I followed https://github.com/xbmc/xbmc/blob/master/docs/README.Fedora.md
I cloned kodi and checkout branch Omega.
I installed compiler and all packages. libusb-devel was not found - so I installed libusb1-devel instead.
Then I switch to https://github.com/xbmc/xbmc/blob/master/docs/README.Linux.md
I followed the given instructions.
But now I am blocked at sudo make -C tools/depends/target/wayland-protocols PREFIX=/usr/local
First meson was missing. I installed it.
Next I run into:

$ LANG=C sudo make -C tools/depends/target/wayland-protocols PREFIX=/usr/local
make: Entering directory '/home/karl/kodi/tools/depends/target/wayland-protocols'
cd native/build; /bin/ninja -v install
ninja: error: loading 'build.ninja': No such file or directory
make: *** [Makefile:54: .installed-native] Error 1
make: Leaving directory '/home/karl/kodi/tools/depends/target/wayland-protocols'

I have no idea how to fix this.

I'm not a Linux guy. Maybe @howie-f can help?

[howie-f]

hi, @kkarsten62 unfortunately our build instructions for linux are somewhat outdated and i am on debian not fedora, but i'll try to help.

Let's assume you cloned the kodi repo to ~/xbmc. in case you cloned somewhere else (example ~/kodi) you would need to adjust the cmake command below accordingly.

so, first check out the omega branch.

fhw@xbmc-build:~/xbmc (master) $ git checkout Omega
Switched to branch 'Omega'
Your branch is up to date with 'origin/Omega'.
fhw@xbmc-build:~/xbmc (Omega) $

Then create the build directory and change into it:

fhw@xbmc-build:~/xbmc (Omega) $ mkdir pvr.hts-build && cd pvr.hts-build
fhw@xbmc-build:~/xbmc/pvr.hts-build (Omega) $

Next configure the build of pvr.hts with cmake (adjust the path ../../xbmc/cmake/addons, if needed)

cmake -DADDONS_TO_BUILD=pvr.hts \
          -DCMAKE_BUILD_TYPE=Debug \
          -DPACKAGE_ZIP=1 \
          ../../xbmc/cmake/addons

you should see something like

-- Configuring done
-- Generating done
-- Build files have been written to: /home/fhw/xbmc/pvr.hts-build

then build: make

-- Installing: /home/fhw/xbmc/pvr.hts-build/.install/pvr.hts/pvr.hts.so.21.1
-- Installing: /home/fhw/xbmc/pvr.hts-build/.install/pvr.hts/pvr.hts.so
[ 55%] Completed 'pvr.hts'
[100%] Built target pvr.hts

then package: make package-pvr.hts

CPack: Create package
CPack: - package: /home/fhw/xbmc/pvr.hts-build/pvr.hts-prefix/src/pvr.hts-build/addon-pvr.hts-21.2.5-linux.zip generated.
Built target addon-package
[100%] Built target package-pvr.hts

then install the zip on your target...
i hope this helps

[kkarsten62]

Many thanks for your clear instructions. It`s works w/o any problem.
I see the zip file:

...

I guess you know that...
I use always for huge compilation make -j$(nproc). Then all processors of my computer has something to do :-)

Later on I will check with the build zip, whether I see more for the related crash.

I am unsure how to debug now with the debug addon?!
I just did the following according to: https://docs.flatpak.org/en/latest/debugging.html

We need debug symbols, but I have no idea how to achieve this.
