arch/ffmpeg-v4l2-request-git: FFmpeg 8.1 + V4L2-Request hwaccel for Fourier
First carrier package for the Fourier umbrella. Tracks Kwiboo's
v4l2-request-n8.1 branch (ffmpeg 8.1 base) pinned at commit b57fbbe —
bump _commit to rebase onto newer tip. CI job chained after
claude-his-any so it serializes on the shared aarch64 repo-db;
continue-on-error: true so long ffmpeg builds don't block the debian
downstream.

Deliberately diverges from the AUR package:

- AUR pins 6.1.1 with epoch=2 → would downgrade stock Arch ffmpeg 2:8.1-3.
  We track 8.1 so install is a sideways swap, not a regression.
- AUR pulls X11/AMF/CUDA/FireWire/AviSynth/OpenMPT/Bluray/OpenMAX/JPEG-XL/
  Theora/XVid/rsvg/soxr/ssh/vidstab/modplug/SDL2/Vulkan/JACK/GSM/Speex —
  dropped here; none are needed on a Wayland ARM video-decode fleet.
- AUR uses #branch=…, sha256sums=(SKIP) → every build is tip-of-branch,
  not reproducible. We pin via #commit=<sha>.

Kept: encoders (libx264/libx265/libvpx/libdav1d), VAAPI, libdrm, libv4l2,
neon, OpenGL, PulseAudio, subtitle/font stack, gnutls TLS. SDL2 dropped
means no ffplay binary (mpv covers interactive playback).

provides=(ffmpeg) conflicts=(ffmpeg) so it replaces stock ffmpeg on the
target host deliberately. Primary consumers: ohm (Fourier step 5),
fresnel, ampere.

#
# FFmpeg + V4L2-Request hwaccel (stateless video decode on Rockchip,
# Allwinner, etc) for the Fourier umbrella. Tracks Kwiboo's long-running
# rebase of Jernej Škrabec's v4l2-request patchset onto ffmpeg release
# tags. Pins the branch tip to a known commit for reproducible CI builds;
# bump _commit when upstream picks up a fix we want.
#
# Why this fork instead of AUR ffmpeg-v4l2-request-git:
# - AUR is pinned to 6.1.1 with epoch=2, which is OLDER than Arch's
# stock 2:8.1-3 → installing it downgrades system ffmpeg.
# - AUR pulls X11/AMF/CUDA/FireWire/AviSynth/OpenMPT/Bluray — irrelevant
# for a Wayland + ARM + video-decode fleet.
# - AUR uses #branch=..., no commit pin. CI artifacts are non-reproducible.
#
# Encoders (libx264/libx265/libvpx/libdav1d) kept per Fourier fleet policy.
# X11, AMF, CUDA, FireWire, AviSynth, OpenMPT, Bluray, OpenMAX, JPEG-XL,
# Theora, XVid, rsvg, soxr, ssh, vidstab, modplug, SDL2, Vulkan, JACK, GSM,
# Speex dropped — not needed on the Fourier fleet. (No SDL2 means no
# `ffplay` binary; mpv covers interactive playback.)
