The libva-v4l2-request-fourier .deb shipped with the wrong VA-API
symbol export because the CI runner is Arch (libva 2.23 = VA-API
1.23) while the install target is Debian trixie (libva 2.22 = VA-API
1.22). At compile time, <va/va.h>'s VA_MAJOR/VA_MINOR macros are
baked into the driver's __vaDriverInit_<MAJOR>_<MINOR> symbol name.
trixie's libva runtime looks up __vaDriverInit_1_22, our driver only
exported __vaDriverInit_1_23, so dlsym() returned NULL and libva
fell back to its sentinel error "has no function __vaDriverInit_1_0".
Result: ffmpeg -hwaccel vaapi fails on startup, vainfo fails the
same way, on every Pi 5 / CM5 that installed the package.
The driver itself doesn't link libva.so (no NEEDED entry — confirmed
via readelf on higgs), so the only thing that matters is the symbol
NAME the compiler bakes in. Fix is small: in build-deb.sh, download
trixie's libva-dev / libva2 / libva-drm2 .deb from deb.debian.org,
extract to a sysroot, rewrite the .pc prefixes, and set
PKG_CONFIG_PATH so pkg-config returns trixie headers regardless of
what the runner has installed. The link step still resolves -lva
against the sysroot's libva.so.2, but the resulting .so has no
NEEDED entry for it.
Added a hard sanity check at the end of build-deb.sh: fail the build
if the produced .so doesn't export __vaDriverInit_1_22. This makes
future ABI-skew failures loud at CI time instead of silent install-
then-refuse-to-load on the target.
Tested on boltzmann (aarch64): sysroot build produces a .so exporting
__vaDriverInit_1_22 (verified via nm -D). Source unchanged from
c332d34; only the build env differs.
pkgver/upstream unchanged. PKGREL bumped 1 -> 2 (rebuild against
pinned trixie libva-dev) so apt picks up the new .deb on higgs.
This is the LIBVA-2 unblocker — the runtime-libva-bind failure was
masking whether the LIBVA-1 per-codec dispatch actually works on
higgs. Once -2 lands on packages.reauktion.de, apt upgrade on higgs
and the daedalus daemon log + rpi-hevc-dec dispatch can be validated
end-to-end.

Bumps both Arch (PKGBUILD) and Debian (build-deb.sh + changelog)
pins to upstream c332d34 — the merged LIBVA-1 PR.
Effect: Pi 5 / CM5 mixed deployment (higgs) now opens BOTH
rpi-hevc-dec and daedalus_v4l2 from one libva session and routes
per-codec — HEVC to rpi-hevc-dec ('p'), VP9 / AV1 / H.264 to the
daedalus daemon (new 'd' kind). Before c332d34, find_codec_device
picked rpi-hevc-dec by known_decoder_drivers[] order and the
daedalus slot stayed -1, so VP9/AV1/H.264 frames failed S_FMT.
Also closes a small fd leak in RequestTerminate (daedalus pair —
caught while reviewing the alt-driver expansion).
Both packages: pkgver bumped 1.0.0.r378.c332d34, pkgrel reset to 1
(new upstream pin). Backward-compatible on RK3399/3588 — new
branches gated by HAVE_DAEDALUS_V4L2 *and* video_fd_daedalus >= 0,
both false in those deployments.
Companion: daedalus-v4l2{,-dkms} bump 481279c landed in PR #39
(systemd unit + auto-enable). Together they close the Pi 5 stack:
boot → modules-load.d loads daedalus_v4l2 → daedalus-v4l2.service
starts daemon → libva opens both decoders → ffmpeg -hwaccel vaapi
routes by codec.

Mirror of arch/libva-v4l2-request-fourier into the Debian tree.
Same pin (de27e95), same build (meson + ninja), output as
arm64 .deb installing the VA-API ICD as
/usr/lib/aarch64-linux-gnu/dri/v4l2_request_drv_video.so.
Auto-detected by VAAPI consumers (ffmpeg -hwaccel vaapi, mpv
--hwdec=vaapi, Firefox VAAPI accel) when
LIBVA_DRIVER_NAME=v4l2_request is set.
build-deb.sh follows the lmcp pattern: reproducible build with
SOURCE_DATE_EPOCH pin; standalone dpkg-deb so it runs on a
non-Debian builder without dh/debhelper.
