mpv on ohm is currently stock arch from [extra]. To ship the vo_dmabuf_wayland plane-semantics fix per marfrit/dmabuf-modifier-triage#1, we need an mpv-fourier package following the same fourier-umbrella pattern as kwin-fourier, qt6-base-fourier, firefox-fourier, libva-v4l2-request-fourier. This commit lays down: - arch/mpv-fourier/PKGBUILD pinning upstream mpv 0.41.0 tarball, with empty patch slot in prepare(). replaces=mpv. provides=mpv,libmpv.so. When iter1 produces the patch, add it to source=()/sha256sums=() and uncomment the patch -p1 line. - arch/mpv-fourier/README.md documenting why + tracker links - .gitea/workflows/build.yml job mpv-fourier-aarch64 chained after libva-v4l2-request-fourier-aarch64 for marfrit.db serialization. Same fermi LXC runner, same makepkg → sign → repo-add → rsync flow. Initial scaffold builds vanilla mpv 0.41.0 with no fourier patches — once iter1 lands, bump pkgrel and add the patch.

mpv-fourier
mpv with the fourier-umbrella patches.
Why
The dmabuf-modifier-triage campaign isolated the green-frames bug on ohm
to mpv's vo_dmabuf_wayland.c plane-semantics handling for V4L2 stateless
decoder dmabufs. mpv currently emits a zwp_linux_buffer_params_v1
message that mixes per-plane fds (V4L2 MPLANE export) with a single-
allocation offset for plane 1, causing KWin to read the UV chroma plane
past-EOF on the UV-plane fd and render solid dark green.
This package is the delivery vehicle for the fix once it's written. PKGBUILD is in place with an empty patch slot; the patch itself is iter1 of the triage campaign.

Status
- 2026-05-08: scaffold landed. Builds vanilla mpv 0.41.0 with no
fourier patches applied (patch slot empty in
prepare()). pkgrel=1 pinned to mpv release v0.41.0.
When iter1 of the triage campaign produces the patch, bump pkgrel,
add the patch to source=() and sha256sums=(), uncomment the
patch -p1 line in prepare().
Hosts that benefit
Only hosts that exercise the V4L2 stateless dmabuf-wayland path — ohm (RK3566 + hantro G1) today, fresnel (RK3399 + hantro + rkvdec) once that campaign reaches its mpv-test phase. Other hosts on [marfrit] (boltzmann, hertz desktop) won't see any difference as the fix is no-op for non-V4L2-stateless dmabuf paths.
