The Decky plugin (b3f98a5) launches `punktfunk-client`, but the Arch package only
shipped the host, so the Deck had nothing to launch. Convert the PKGBUILD to a
split package (pkgbase=punktfunk → punktfunk-host + punktfunk-client), mirroring the
rpm subpackages and the two deb build scripts:
- punktfunk-host: unchanged artifact set + NVENC/compositor optdepends.
- punktfunk-client: the GTK4 binary + io.unom.Punktfunk.desktop + the hidraw udev
rule + the 32MB recv-buffer sysctl; depends gtk4/libadwaita/sdl3/ffmpeg/pipewire/
opus; optdepends libva-mesa-driver (VAAPI decode on the Deck's AMD APU, software
fallback otherwise). New punktfunk-client.install scriptlet.
- build-sysext.sh now derives the package name from the file, so it wraps either the
host OR the client into a systemd-sysext .raw — on a Deck you wrap the client.
- README: split-package usage + a "Steam Deck (the client)" section tying the sysext
to the Decky plugin (client is on PATH → plugin launches `punktfunk-client
--connect host:port`). Clarified the VAAPI gap is host-ENCODE only; the client
DECODES via VAAPI on the Deck today, so streaming to a Deck works now.

# Arch Linux / SteamOS split package: punktfunk-host (the gaming-rig HOST, NVENC) and
|
|
# punktfunk-client (the GTK4 couch/Deck CLIENT). Mirrors the rpm subpackages
|
|
# (packaging/rpm/punktfunk.spec) and the two deb build scripts. On a Steam Deck you want
|
|
# `punktfunk-client` (it's what the Decky plugin launches); on a gaming rig, `punktfunk-host`.
|
|
#
|
|
# Two build modes:
|
|
# - AUR / standalone: makepkg in this dir (fetches the git tag below).
|
|
# - In-tree / CI: PF_SRCDIR=$(git rev-parse --show-toplevel) makepkg --holdver
|
|
# (builds the working tree instead of the tagged source — see build()).
|
|
#
|
|
# IMPORTANT: host encode is NVENC-only (crates/punktfunk-host/src/encode/linux.rs) — functional on
|
|
# NVIDIA hosts; an AMD Deck-as-HOST needs a VAAPI backend first. The CLIENT decodes via VAAPI
|
|
# (AMD/Intel, incl. the Deck) with a software fallback, so it works everywhere. See README.md.
