yeah seems like release was overwritten or regenerated. patched checksum

There seems to be an issue with the checksums

Applied both of @brody 's recommendations. Thanks!

Thanks @brody for that hint. Now I can build the package and seemingly the applications runs fine, so unless you've found something else I'm gonna say this fixes the issue for good.

@Smoerrebroed I could repoduce the error.

To fix the build process I added a prepare() part to the PKGBUILD file.

prepare() {
  sed s'|==|>=|g' -i ${_reponame}/requirements.txt
}

But I need to check the installed package for issues.

Has anybody tried building/installing recently? I'm running an up-to-date Arch system, but building this package I end up with:

ninja: build stopped: subcommand failed.
[end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed

× Encountered error while generating package metadata.
╰─> numpy

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.

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 &
