# mpv-fourier — mpv with the fourier-umbrella patches. The first patch
# slot exists for the vo_dmabuf_wayland plane-semantics fix per
# marfrit/dmabuf-modifier-triage#1: mpv currently constructs the
# zwp_linux_buffer_params_v1 wl_protocol message with internally
# inconsistent plane semantics on V4L2 stateless decoder dmabufs (per-
# plane fds combined with single-allocation offset for plane 1), causing
# KWin to read the UV chroma plane past-EOF and render solid dark green
# on ohm (RK3566 + hantro G1 + Mali-G52). The patch is not yet written —
# this scaffold prepares the shipping path for when iter1 lands.
#
# Campaign: ~/src/dmabuf-modifier-triage/ (Phase 0 closed 2026-05-08)
# Upstream: https://github.com/mpv-player/mpv
# Build target: fermi LXC actrunner-aarch64-hertz via marfrit-packages
# Gitea Actions; alternative: boltzmann via his subagent + marfrit-publish.

    # Patch slot — iter1 of dmabuf-modifier-triage will produce the actual
    # vo_dmabuf_wayland.c plane-semantics fix and add it as 0001-... here.
    # Once the libva path is also unblocked (by libva-multiplanar iter9)
    # and the WAYLAND_DEBUG verifier confirms whether the bug is purely in
    # mpv's VO or also in libva/ffmpeg producer code, the exact patch
    # shape is determined.
    #
    # When the patch lands, add it to source=() above + sha256sums=() and
    # uncomment the patch -p1 below.
    #
    # patch -p1 < "${srcdir}/0001-vo_dmabuf_wayland-plane-semantics.patch"
