Run #70 actually succeeded at the pacman level (log shows ffmpeg removed and ffmpeg-v4l2-request-fourier installed) but the step exited non-zero. Cause: bash's set -o pipefail (Gitea Actions default) sees `yes` get SIGPIPE'd when pacman closes its stdin, yes exits 141, pipeline reports 141 → step fails. Replace `yes y | pacman -S ...` with finite-stream printf that exits 0 cleanly. Three y's cover all expected prompts. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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.
