Ship the punktfunk Linux client to the Steam Deck as a Flatpak — the only viable
SteamOS install path, since /usr is read-only and lacks libadwaita/SDL3 — and
publish both it and the Decky plugin through Gitea. Built and validated live on a
Steam Deck (SteamOS 3.7): bundle installs user-scope, all libs resolve, libavcodec
resolves to the codecs-extra HEVC build, devices=all for DualSense hidraw.
packaging/flatpak (new):
- io.unom.Punktfunk.yml on GNOME 50 / freedesktop-sdk 25.08. rust-stable//25.08
(rustc 1.96 — the GTK4 chain needs >=1.92; the EOL GNOME-48/24.08 rust-stable at
1.89 could not build it) + llvm20 (libclang for bindgen in ffmpeg-sys-next/sdl3-sys).
HEVC libavcodec comes from the runtime's auto codecs-extra extension point (no
app-side codec declaration). Bundled SDL3 3.4.10 (matches sdl3-sys 0.6.6+SDL-3.4.10).
finish-args: wayland/fallback-x11, --device=all (GPU/VAAPI + evdev + hidraw — flatpak
cannot bind /dev/hidrawN char devices via --filesystem), pulseaudio, network,
~/.config/punktfunk.
- metainfo.xml, desktop, square SVG icon, build-flatpak.sh (offline cargo-sources;
on-Deck org.flatpak.Builder or CI), README.
clients/decky:
- add LICENSE (MIT), fix package.json license (BSD-3-Clause -> Apache-2.0 OR MIT),
add scripts/{package.sh,deploy.sh} (the plugins dir is root-owned: stage to /tmp,
sudo install, restart plugin_loader), align the launcher fallback to the real
flatpak app id io.unom.Punktfunk, rewrite the install section.
.gitea/workflows:
- flatpak.yml: privileged Fedora container builds the bundle and publishes to the
Gitea generic registry (+ release attachment on tags).
- decky.yml: pnpm build -> store-layout zip -> registry (stable latest/ URL for
Decky "install from URL").

Packaging punktfunk for Fedora / Bazzite
The punktfunk host is Linux-only and links system FFmpeg (NVENC), PipeWire, Opus and the NVIDIA driver. This directory packages it for the Fedora Atomic / Bazzite world (rpm-ostree + bootc), where most of those deps are already present.
👉 Ubuntu/Debian hosts install via
aptfrom Gitea's package registry — seedebian/README.md(apt update && apt upgradefor new builds).
👉 End-to-end Bazzite setup walkthrough (install → udev/group →
host.env→ service → firewall → verify → troubleshooting):bazzite/README.md. This file is the higher-level packaging rationale.

What's needed beyond base Fedora
| Dependency | Where it comes from |
|---|---|
ffmpeg-libs with NVENC |
RPM Fusion nonfree (ffmpeg, not ffmpeg-free) |
NVIDIA driver (libnvidia-encode, libEGL_nvidia) |
Bazzite -nvidia images ship it; plain Fedora: akmod-nvidia + xorg-x11-drv-nvidia-cuda |
| gamescope, PipeWire, wireplumber | Bazzite ships these; plain Fedora: dnf install gamescope pipewire wireplumber |
opus, libei |
Fedora base / updates |
On Bazzite the only genuinely new runtime bits are ffmpeg-libs (RPM Fusion) + opus +
libei — the rest of the stack is already there. The default backend is gamescope
(packaging/bazzite/host.env), which the host spawns headless per session — no desktop login.
Option A — Gitea RPM registry (recommended; per-host, rpm-ostree)
The host's RPM is published to unom's self-hosted Gitea RPM registry (CI builds it on every
push), mirroring the Debian/apt setup. Add one repo file, install, and track
updates with rpm-ostree upgrade — no COPR account needed. Full guide: rpm/README.md.

REPO
rpm-ostree install punktfunk && systemctl reboot
# updates: rpm-ostree upgrade && systemctl reboot
Option B — COPR (per-host, rpm-ostree install)
- Create a COPR project, enable build-from-SCM pointing at this repo, spec path
packaging/rpm/punktfunk.spec(seecopr/README.md). Under External Repositories add RPM Fusion nonfree soffmpeg-develresolves at build time. - On the Bazzite host:
# RPM Fusion (for the NVENC ffmpeg) — usually already enabled on Bazzite rpm-ostree install \ https://mirrors.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm \ https://mirrors.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm # enable the COPR + install punktfunk sudo wget -O /etc/yum.repos.d/_copr_punktfunk.repo \ https://copr.fedorainfracloud.org/coprs/enricobuehler/punktfunk/repo/fedora-$(rpm -E %fedora)/ rpm-ostree install punktfunk systemctl reboot
Option B — bootc (image-based, atomic)
Layer punktfunk into a Bazzite image once, then rebase any number of hosts onto it — no
per-host drift. See bootc/Containerfile:
podman build -t ghcr.io/<you>/bazzite-punktfunk -f packaging/bootc/Containerfile .
podman push ghcr.io/<you>/bazzite-punktfunk
# on the target:
sudo bootc switch ghcr.io/<you>/bazzite-punktfunk && systemctl reboot
First-run setup (either option)
ujust add-user-to-input-group # virtual gamepads need /dev/uinput (then re-login).
# On Bazzite use ujust, NOT `usermod -aG input` (atomic OS — it won't stick).
mkdir -p ~/.config/punktfunk
cp /usr/share/punktfunk/host.env.bazzite ~/.config/punktfunk/host.env # edit (gamescope app, etc.)
systemctl --user enable --now punktfunk-host
Pair a stock Moonlight client (mDNS-discovered), or connect the native punktfunk/1 client.
Why not Flatpak (for the HOST)?
The host needs unsandboxed access the zero-copy NVENC path, /dev/uinput, the PipeWire
graph and the compositor's privileged protocols — a Flatpak sandbox fights all of these.
An RPM (or the bootc layer) installs into the host system where those just work.
👉 The client is a different story — it IS shipped as a Flatpak (the only viable Steam Deck install path: SteamOS
/usris read-only and lackslibadwaita/libSDL3). Seeflatpak/README.md. The client sandbox only needs the GPU render node, Wayland, PipeWire audio, the network and hidraw — all expressible as finish-args.
Building the SRPM/RPM locally (Fedora only)
git archive --format=tar.gz --prefix=punktfunk-0.0.1/ -o ~/rpmbuild/SOURCES/punktfunk-0.0.1.tar.gz HEAD
rpmbuild -ba packaging/rpm/punktfunk.spec # needs the BuildRequires from the spec
(Not buildable on Debian/Ubuntu — use a Fedora toolbox/container or COPR.)
