Expected Behavior

Custom plugins should be able to load. The native arch linux package works fine, but not the flatpak.

Current Behavior

Custom plugins fail to load. This was also tested on a debian virtual machine with the flatpak version, same error.

Steps to Reproduce

1. Install a custom plugin, you can use "com.obsproject.Studio.Plugin.OBSVkCapture" from flathub to test it
2. Check the current log if it has loaded.

Anything else we should know?

Can duplicate on ubuntu 22.04
Any plugin installed via flathub doesn't even log an attempt to load.
Plugins installed by copying in the plugins config folder fail to load with :
os_dlopen(/app/plugins/lib/obs-plugins/linux-vkcapture.so->/app/plugins/lib/obs-plugins/linux-vkcapture.so): libobs.so.0: cannot open shared object file: No such file or directory

The flatpak version loads manually installed plugins from $HOME/.var/app/com.obsproject.Studio/config/obs-studio/plugins/

Those fail as well. Worked fine on the previous version.

Just to set the scope of the issue:

• Plugins manually installed (copy-paste in the config folder) are not supported in the Flatpak and never was.
• "Flatpak extensions can't be loaded since 30.2" is the scope of the issue

The easiest solution, would be to have every extension re-built against the latest Flathub.

I asked Flathub, I'll see how it is going.

[lefty82]

That leaves the issue with extensions that are not through FP, and just dropped in $HOME/.var/app/com.obsproject.Studio/config/obs-studio/plugins/

I guess it will be up to the individual devs for those

[tytan652]

Flathub accepted to start re-build of plugins, in +3 hours most of the re-built plugins will be pushed to Flathub.

If a plugin is not re-built (in the next 24 hours), please open an issue on it's Flathub manifest repo.

Like I said we don't support this, for the Flatpak we only support Flatpak extensions.

Also having this issue, the OBSVkcapture plugin is not working for me (installed via the flatpak)

Works fine when I downgrade the OBS flatpak to the previous version.

Unfortunately, 27 hours later and none of the extensions appear to have been modified.

Rolled back for now, but has anyone got more info on what's being done atm?

I'm having the same issue. None of the plugins are loading. Tried to rollback but I OBS wouldn't open after that.

Any workarounds?

[tytan652]

Re-build have been normally publish unless the build failed or the plugin did not keep up with KDE Sdk updates.

If a plugin is not re-built (does not work), please open an issue on the Flathub manifest repo.

Hello,

I help maintain the Waveform Flatpak plugin, and, from what I can see, no rebuild has been triggered for it: https://buildbot.flathub.org/#/apps/com.obsproject.Studio.Plugin.waveform

I tried to manually build it and update it to the latest KDE SDK, but the build fails because it's not finding an OBS symbol:

Please let me know if you have any idea on how to resolve this.

@rmnvgr, outdated SDK, for the build error this is an issue with upstream plugin CMake from what I see.

Issues are not meant for support. So for maintainers, for further assistance either the OBS Comnunity Discord or the Flathub Matrix.
