It would be great if you could modify the PKGBUILD file to comply with FHS standards. This means not using the /usr/local/ directory, as it is intended for software installed manually (by an administrator with the appropriate write permissions) and not for packages from the package management system.

An alternative to “${pkgdir}”/usr/local/lib/streamcontroller could be “${pkgdir}”/usr/lib/streamcontroller/venv.

I have tested this change myself.

with the release of beta14 this should build properly now. no need to use -git unless you prefer latest.

FYI, If this is not an appropriate location to discuss issues, please point me to the correct place.

I've followed your instructions, with a few changes to file pathing, and I've got it successfully installed. However, if I try to create an OBS action, it doesn't work. I've tried installing the streamcontroller-git package off the AUR and it installs without issue but has the same issue with OBS actions. So, I would assume that package needs to be fixed/updated as well.

It looks like the OBS plugin is broken. If I try to open the plugin settings it just displays a blank window.

This is the error when trying to add an OBS action: AttributeError: 'NoneType' object has no attribute 'get_connected' 2026-01-25 20:33:44.430 | DEBUG | src.backend.PageManagement.Page:load:86 - Loaded page Streaming in 0.09 seconds

This is the error when trying to open settings: (StreamController:31380): Gtk-WARNING **: 20:35:07.234: Failed to set text 'Performance & Optimizations' from markup due to error parsing markup: Error on line 1: Entity did not end with a semicolon; most likely you used an ampersand character without intending to start an entity — escape ampersand as &

PR I mentioned has been merged, but this version is still pinned to a tag. For now, I'd recommend installing https://aur.archlinux.org/packages/streamcontroller-git or using the patches below.

Independent of whether streamcontroller it is already installed:

1. Save the diff below as ~/Downloads/requirements.diff
2. (Try to) install via yay -S --answerclean All --answerdiff None --rebuildall streamcontroller – this will lead to the error
3. Apply the patch via patch ~/.cache/yay/streamcontroller/src/StreamController-1.5.0-beta.13/requirements.txt < ~/Downloads/requirements.diff – this applies the patch to the requirements.txt that was previously downloaded and extracted in the yay cache
4. Install via yay -S --answerclean None --answerdiff None --mflags="-e" streamcontroller – this re-runs the make/install process without cleaning up (download/extract) the cache first
5. Party!

On a fresh install, how can the requirements.txt be patched? Or is this something you can do @NOSDuco? At least until the github issue you posted is merged?

Hey all, aware of the python3.14 issue. Please follow @Treyfane's recommendation for now, and once https://github.com/StreamController/StreamController/pull/532#issuecomment-3740476012 is merged, it will be fixed downstream.

The Levenshtein – and subsequent RapidFuzz error – can be avoided with the following patch to requirements.txt in the source:

Today's python update to 3.14 breaks streamcontroller with the error:
