Lock-step downgrade of both packages to the revert tip of daedalus-v4l2 (PR #10 closed PRs #7 + #8). After 0.1.0+r28+g79256dc-1 / 0.1.0+r30+g6ffe92b-1 landed in production, mpv (--hwdec=vaapi-copy) failed pre-playing with "Unable to dequeue buffer: Resource temporarily unavailable" because the daemon parked CAPTURE buffers waiting for libavcodec's display-order reorder, violating libva's V4L2 stateless 1:1 contract. See daedalus-v4l2#9 for the diagnostic, #10 for the revert PR. DAEDALUS_PROTO_VERSION drops 1 → 0; install both .debs in the same apt transaction. Userspace ABI returns to the f0d4186-equivalent behaviour, plus PR #4 (cosmetic H.264 menu controls). The daedalus-v4l2-dkms #64 multi-kernel postinst behaviour stays in build-deb.sh. Visible regression: H.264 B-frame streams in Firefox return to the "2 1 4 3 6 5" pair-swap visual. Proper fix (concurrent in-flight requests in daemon + display-order reorder moved into libva-v4l2- request-fourier) tracked at daedalus-v4l2#11.

# daedalus-v4l2-dkms — DKMS package for the daedalus_v4l2 out-of-tree
|
|
# kernel module (V4L2 stateless decoder shim for Pi 5 / CM5).
|
|
#
|
|
# Pair to daedalus-v4l2 (userspace daemon). When loaded, the module
|
|
# registers /dev/videoNN (V4L2 m2m) + /dev/mediaNN (media controller) +
|
|
# /dev/daedalus-v4l2 (chardev to the userspace daemon). Userspace
|
|
# clients drive the V4L2 m2m + request API path; the daemon does the
|
|
# actual FFmpeg-backed decode on /dev/daedalus-v4l2.

# 5d8b436 reverts PRs #7 + #8 (parking design that broke libva's

# content-equivalent to f0d4186 plus PR #4 (cosmetic menu ctrls).
