Per @marfrit on PR #44 review: a native Debian trixie aarch64 runner (debian-aarch64-bohr) is available — use it instead of the sysroot hack from the previous commit. The sysroot approach worked but was a workaround for not having the right runner. Native trixie runner is much cleaner: - libva-dev installs via apt-get directly from trixie's archive (2.22.0-3) — pkg-config returns trixie headers, driver compiles in __vaDriverInit_1_22 naturally. - No need to symlink libva.so.2 -> libva.so or rewrite .pc prefixes. - No bsdtar/ar/dpkg-deb juggling on an Arch runner that doesn't natively have dpkg. Changes from PR v1: - .gitea/workflows/build.yml: libva-v4l2-request-fourier-debian runs-on: debian-aarch64-bohr (was arch-aarch64). Build-deps installed via apt-get instead of pacman -Syu. - build-deb.sh: drop the sysroot download / pkgconfig rewrite / symlink block. Keep the post-build ABI sanity check (nm -D | grep __vaDriverInit_1_22) — same defensive role as before, with an updated error message that points to the expected runner. - debian/.../changelog: -2 entry rewritten to describe the runner move instead of the sysroot. Tested approach on boltzmann (aarch64): meson build against trixie sysroot produces __vaDriverInit_1_22 (proves the source compiles correctly with VA-API 1.22 headers). Native runner build will follow the same path, just without the explicit sysroot setup. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Description: VA-API backend for V4L2 stateless decoders (fourier fork)
|
|
LibVA implementation for the Linux Video4Linux2 Request API, multiplanar
|
|
fork of bootlin/libva-v4l2-request. Drives rkvdec / hantro / cedrus /
|
|
rpi-hevc-dec / daedalus_v4l2 stateless decoders for H.264, HEVC, VP8,
|
|
VP9, AV1, and MPEG-2.
|
|
.
|
|
Auto-detected by VAAPI consumers (ffmpeg -hwaccel vaapi, mpv --hwdec=vaapi,
|
|
Firefox VAAPI accel) when LIBVA_DRIVER_NAME=v4l2_request is set.
