Arch Linux: Recording a selection of a screen ends in `Failed to find element factory with name 'glsinkbin' for creating element`

[VeldoraTheDragon]

Affected version

- io.github.seadve.Kooha 2.3.0
- Flatpak: false
- Experimental Features: []

- Language: en_US.UTF-8, en_US, en.UTF-8, en, C

- CPU: 12th Gen Intel(R) Core(TM) i7-1260P
- GPU: Intel Corporation Alder Lake-P GT2 [Iris Xe Graphics] (rev 0c)

- Distribution: Arch Linux (Timestamp: 2024-04-04 09:39 | Kernel: 6.8.2)
- Desktop Session: gnome
- Display Server: x11

- GTK 4.14.2
- Libadwaita 1.5.0
- GStreamer 1.24.1
- Pipewire 1.0.4

The display server says x11, though according the gnome system details it's wayland.

Bug summary When trying to capture a selection of a screen, it can't be recorded and ends in:

Failed to find element factory with name 'glsinkbin' for creating element

Steps to reproduce

1. Install Kooha from the Arch Repo: pacman -Syu kooha
2. Open Kooha
3. Click on Capture a Selection of Screen
4. Click Record
5. Select Screen, which should get recorded
6. See error

Expected behavior The window which selection should get recorded should open, as it does in the current flatpak development-build.

Relevant logs, screenshots, screencasts, etc.

[SeaDve]

It seems you are missing a dependency, something like gstreamer-plugins-base

[SeaDve]

It works with flatpak build since every dependencies is bundled

[VeldoraTheDragon]

I see, thank you for the hint. I'll open a bug-report (if not already one present) at Arch Linux to add gst-plugins-base as a dependency. This did the trick.

Thank you for your quick answer.

I've updated the Arch Linux package per the packaging bug report.
