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. Refs: * reauktion/daedalus-v4l2#12 * reauktion/daedalus-v4l2#13 * reauktion/daedalus-v4l2#11 * marfrit/daedalus-fourier#1

# daedalus-v4l2 — userspace daemon + V4L2 m2m test tools.
|
||
#
|
||
# Pair to daedalus-v4l2-dkms (kernel module). Together they expose
|
||
# /dev/videoNN + /dev/mediaNN as a V4L2 stateless decoder shim on Pi 5 /
|
||
# CM5, decoding VP9 / AV1 / H.264 via dlopen'd FFmpeg in a single-
|
||
# threaded daemon and shipping decoded NV12 / P010 back through dmabuf.
|
||
# Consumed end-to-end by libva-v4l2-request-fourier (>= 1.0.0.r376) so
|
||
# `ffmpeg -hwaccel vaapi` against vp9_small.ivf produces byte-exact NV12.
