punktfunk-host builds unchanged against either FFmpeg 7.x (libavcodec 61) or 8.x
(libavcodec 62) — ffmpeg-sys-next auto-detects the system version, and the host's
ffmpeg FFI only touches long-stable APIs. Confirmed by building + running live on a
Bazzite F43 box (FFmpeg 7.1.3): full gamescope capture → zero-copy dmabuf→CUDA →
NVENC H.265 at 1280x720x60, p50 ~0.96 ms. Just doc/spec accuracy, no code change:
- encode/linux.rs + CLAUDE.md: drop the "FFmpeg 8 only" claim; note 7.x/8.x both work.
- rpm spec: add the missing zero-copy GPU build deps the link actually needs —
pkgconfig(gl) + pkgconfig(gbm) (mesa) — and document that -lcuda needs libcuda.so at
link time (NVIDIA host, or the CUDA toolkit stub on a headless COPR/koji builder).
Tracked for a proper fix: make the cuda/gbm/GL FFI dlopen-based like khronos-egl so
the RPM builds on a GPU-less host.

Roadmap #3 (install on other devices). Bazzite already ships gamescope + PipeWire + the
NVIDIA stack, so the host slots in with minimal new deps (ffmpeg-libs from RPM Fusion + opus
+ libei).
- packaging/rpm/punktfunk.spec — builds punktfunk-host from source (cargo), installs the
binary + udev rule + systemd user unit + headless helpers; Requires/Recommends mapped from
the Ubuntu bootstrap deps to Fedora.
- packaging/bootc/Containerfile — layer punktfunk into a bazzite-nvidia bootc image for
atomic, image-based installs.
- packaging/bazzite/host.env — gamescope-default appliance config (spawned per session).
- packaging/copr/ + packaging/README.md — COPR build-from-SCM settings + install docs
(rpm-ostree and bootc paths), and why not Flatpak.
- LICENSE-MIT + LICENSE-APACHE — materialize the declared `MIT OR Apache-2.0` (was unfiled);
the RPM ships them.
Not buildable on the Ubuntu dev box (no rpm tooling) — the COPR/Fedora build is operator-run;
all spec-referenced files verified present and the cargo build is green.
