Provide an aarch64 OBS Studio package for the default application set

Request

Could we provide a maintained obs-studio package for aarch64, either through Omarchy's ARM repository or in coordination with Arch Linux ARM?

OBS is in the current base application list, but I could not find an installable package in the tested ARM repositories.

Evidence, September 6

• Physical Lenovo Yoga Slim 7x / Snapdragon X Elite, Arch Linux ARM, Omarchy 4.0.1rc3-1.5.
• pacman -Si obs-studio reports that the package was not found with core, extra, alarm, and aur configured. The local extra.db was dated September 6; I did not perform a partial system upgrade to test this.
• The separately downloaded https://pkgs.omarchy.org/edge/aarch64/omarchy.db contains 115 entries, but no obs-studio entry.
• Add native AArch64 package build support #240 adds many missing ARM applications, including Obsidian and Pinta, but its package scope does not include OBS.
• The OBS project already has an ARM64 Flatpak request; a maintainer describes that work as in progress without an ETA. I am not proposing a duplicate OBS feature request.

This is a distribution/build-availability request, not evidence that the OBS source cannot run on ARM. A useful first acceptance target would be a native, signed package that launches on Wayland and supports PipeWire screen capture and available camera/audio devices. Any missing optional plugins or hardware encoders should be documented explicitly rather than implied to work.
