# 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.)
