# libva-v4l2-request-fourier — VA-API backend for V4L2 stateless decoders,
# multiplanar fork. Successor to the predecessor experimental package
# libva-v4l2-request-ohm-gl-fix (tarball + 18-patch stack); this package
# tracks the campaign fork's git history directly, so iteration sweeps
# (DEBUG removal, follow-up bugfixes) land in a clean linear log.
#
# Campaign: ~/src/libva-multiplanar/ (eight closed iterations as of
# 2026-05-06; iter8 close is the production tip pinned below).
# Fork repo: https://git.reauktion.de/marfrit/libva-v4l2-request-fourier
# Bootlin upstream: https://github.com/bootlin/libva-v4l2-request
#
# Build target: fermi LXC actrunner-aarch64-hertz via marfrit-packages
# Gitea Actions (path=arch/libva-v4l2-request-fourier triggers the
# libva-v4l2-request-fourier-aarch64 job — wire up alongside the existing
# ffmpeg-v4l2-request-git job in .gitea/workflows/build.yml).
# Alternative: boltzmann via his subagent + marfrit-publish.

# Pin the fork tip. 65969da = "iter8 Phase 4: tests/run_perf_binding_cell.sh"
# — last commit on master before fresnel-fourier work started layering
# MPEG-2 rewrites on top of it (2026-05-08). The libva-multiplanar campaign
# closed iter8 at this commit; promote to a later pin only after a future
# iteration closes cleanly.
