svt-av1

• New package, adapted/. Forked from official Arch’s svt-av1 PKGBUILD (gitlab.archlinux.org/archlinux/packaging/packages/svt-av1), which restricts arch=(x86_64) even though upstream SVT-AV1 has NEON support for aarch64 – Arch just never built it there. Local fork adds aarch64 to arch=(), otherwise unmodified.
• Created 2026-09-24 specifically to unblock [[makemkv]]’s ffmpeg7.1 dependency chain on aarch64 (eurobuild14) – see makemkv’s memory file for the full chain. Initially miscategorized as private/ (reasoned “not an AUR package, so not maintained/adapted”); corrected same day – adapted/ is the right fit for “a local fork of any upstream package (AUR or official Arch) with a deliberate local deviation, aiming to contribute upstream eventually”, which is exactly this case. private/ is for packages with no public-interest upstream at all (commercial/ proprietary/EOL software). See arch/adapted/README’s new line for this package.
• Built + published clean for both x86_64 and aarch64, 4.2.0-1, first try. Only oddity: repo_publish.sh’s log shows “ERROR: Package matching ‘svt-av1’ not found” / “ERROR: The built package (svt-av1) is the one in the repo right now!” lines during the run – both benign, expected noise for a brand-new package’s first-ever publish (repo-add’s “search before remove” step finding nothing yet, and checkpkg comparing against an empty prior state) rather than real failures.
