# Maintainer: Markus Fritsche # # 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.) pkgname=ffmpeg-v4l2-request-fourier _srcname=FFmpeg _version='8.1' _commit='b57fbbe50c9b2656fad86a1a7eeabfd2b2a50935' # v4l2-request-n8.1 tip 2026-04-24 pkgver=8.1.r123329.b57fbbe pkgrel=10 # pkgrel=10 — H.264 luma qpel mc20 daedalus-fourier substitution (cycle 9, 2026-05-23) epoch=2 # daedalus-fourier pin. 209a421 = PR #2 merge (Phase 8c — public API # gains daedalus_recipe_dispatch_h264_qpel_mc20 + DAEDALUS_KERNEL_H264_QPEL_MC20). # Cycle 9 closes the libavcodec.so substitution arc started at cycle 6. _daedalus_fourier_commit='209a4218bcb98b91c04f07ad61513bb04adb13ad' pkgdesc='FFmpeg with V4L2 Request API hwaccel (Rockchip / Allwinner stateless decode)' arch=('aarch64') url='https://github.com/Kwiboo/FFmpeg' license=('GPL-3.0-or-later') depends=( alsa-lib bzip2 fontconfig vulkan-icd-loader fribidi gmp gnutls lame libass.so libdav1d.so libdrm libfreetype.so libgl libpulse libva.so libva-drm.so libvorbis.so libvorbisenc.so libvpx.so libwebp libx264.so libx265.so libxml2 opus v4l-utils xz zlib ) makedepends=( cmake git linux-api-headers mesa nasm ninja vulkan-headers ) provides=( libavcodec.so libavdevice.so libavfilter.so libavformat.so libavutil.so libpostproc.so libswresample.so libswscale.so ffmpeg ) conflicts=(ffmpeg) replaces=(ffmpeg ffmpeg-v4l2-request-git) source=("git+https://github.com/Kwiboo/FFmpeg.git#commit=${_commit}" "daedalus-fourier-${_daedalus_fourier_commit}.tar.gz::https://git.reauktion.de/marfrit/daedalus-fourier/archive/${_daedalus_fourier_commit}.tar.gz" '0001-libudev-bypass-fallback.patch' '0002-nv15-to-p010-unpack.patch' '0003-h264-idct4-daedalus-fourier.patch' '0004-h264-idct8-daedalus-fourier.patch' '0005-h264-deblock-luma-v-daedalus-fourier.patch' '0006-h264-restore-low-delay.patch' '0007-h264-qpel-mc20-daedalus-fourier.patch' '0008-h264-deblock-luma-h-daedalus-fourier.patch' '0009-h264-deblock-chroma-daedalus-fourier.patch') sha256sums=('SKIP' 'SKIP' 'SKIP' 'SKIP' 'SKIP' 'SKIP' 'SKIP' 'SKIP' 'SKIP' 'SKIP' 'SKIP') pkgver() { cd "${_srcname}" printf '%s.r%s.%s' "${_version}" \ "$(git rev-list --count HEAD)" \ "$(git rev-parse --short=7 HEAD)" } prepare() { cd "${_srcname}" patch -Np1 -i "${srcdir}/0001-libudev-bypass-fallback.patch" patch -Np1 -i "${srcdir}/0002-nv15-to-p010-unpack.patch" patch -Np1 -i "${srcdir}/0003-h264-idct4-daedalus-fourier.patch" patch -Np1 -i "${srcdir}/0004-h264-idct8-daedalus-fourier.patch" patch -Np1 -i "${srcdir}/0005-h264-deblock-luma-v-daedalus-fourier.patch" patch -Np1 -i "${srcdir}/0006-h264-restore-low-delay.patch" patch -Np1 -i "${srcdir}/0007-h264-qpel-mc20-daedalus-fourier.patch" patch -Np1 -i "${srcdir}/0008-h264-deblock-luma-h-daedalus-fourier.patch" patch -Np1 -i "${srcdir}/0009-h264-deblock-chroma-daedalus-fourier.patch" } build() { # --- daedalus-fourier: build static .a with PIC, install to a # per-build prefix; libavcodec.so links it into the shared object so # H264DSPContext.idct_add (and follow-up kernels) dispatch through # the daedalus recipe layer instead of the in-tree NEON .S code. --- local _fourier_prefix="${srcdir}/fourier-prefix" mkdir -p "${_fourier_prefix}" pushd "${srcdir}"/daedalus-fourier >/dev/null cmake -B build -G Ninja \ -DCMAKE_BUILD_TYPE=Release \ -DCMAKE_POSITION_INDEPENDENT_CODE=ON \ -DCMAKE_INSTALL_PREFIX="${_fourier_prefix}" cmake --build build --target daedalus_core cmake --install build popd >/dev/null cd "${_srcname}" # FFmpeg's configure resolves the compiler via `which` and bakes the # absolute path into generated makefiles, bypassing the makepkg # /usr/lib/distcc/bin shim.
