Daemon-only bump (no daedalus-v4l2-dkms change needed; PROTO_VERSION
stays at 0).
#12 (LOW_DELAY half-measure): daemon sets AV_CODEC_FLAG_LOW_DELAY on
the H.264 AVCodecContext so libavcodec emits frames in decode order
~99% of the time (a few stragglers at GOP boundaries when the
stream's SPS num_reorder_frames overrides the flag). Visible
improvement vs the 2-1-4-3 pair-swap on Firefox + mpv playback;
not the permanent fix — see daedalus-v4l2#11 for the architectural
plan to substitute daedalus-fourier kernels for libavcodec's
pixel math one cycle at a time.
#13 (daedalus-fourier linkage): daemon now pkg-config-links against
the daedalus-fourier kernel library (marfrit/daedalus-fourier) and
logs substrate availability at startup. No kernels dispatched yet
— this is the build-time foundation for the substitution work.
build-deb.sh updated to fetch + build + install daedalus-fourier
(pinned at d87239d, marfrit/daedalus-fourier PR #1) into a per-
build temp prefix before invoking the daemon's cmake, exposing it
via PKG_CONFIG_PATH. Static-linked, so the resulting .deb has no
new runtime deps. Requires libvulkan-dev + glslang-tools on the
CI runner.
Arch PKGBUILD bumped to the same upstream commit but Arch packaging
for daedalus-fourier itself is a follow-up; until that lands the
Arch build expects daedalus-fourier installed by the user (AUR-style).
Debian-side is end-to-end self-contained via build-deb.sh.
