Lock-step bump of both packages to daedalus-v4l2#7 + #4. PROTO_VERSION bumps 0 → 1 at the daemon ↔ kernel chardev wire: REQ_DECODE adds __u64 src_pts (the OUTPUT vb2 timestamp); RESP_FRAME adds __u32 flags (HAS_PIXELS / SRC_CONSUMED) + __u64 output_src_pts (= frame->pts on drain). Both .debs must be installed atomically or the chardev handshake rejects the version mismatch. * daedalus-v4l2: daemon's send_packet → receive_frame loop now stamps pkt->pts = req->src_pts and looks up the cookie for each drained frame via frame->pts. chardev_client emits multiple RESP_FRAME messages per REQ_DECODE when libavcodec's display- order DPB releases an earlier frame on receipt of a later bitstream — fixes the "2 1 4 3 6 5" pair-swap on H.264 streams with B-frames. * daedalus-v4l2-dkms: kernel device_run mirrors src_buf timestamp into REQ_DECODE.src_pts. Completion path splits HAS_PIXELS / SRC_CONSUMED: src is released as soon as send_packet succeeds (so the m2m scheduler moves on), dst stays parked until the matching frame is drained later. TIMESTAMP_COPY's auto src→dst pairing no longer applies once lifecycles decouple — dst is stamped explicitly from inflight->src_pts at HAS_PIXELS time. * daedalus-v4l2-dkms also carries forward the -2 multi-kernel postinst fix (#64) from the prior PKGREL. PKGREL resets to 1 on the new upstream pin. The daedalus-v4l2#4 H.264 DECODE_MODE + START_CODE menu controls (a cosmetic warning fix that PR landed alongside #7) is also subsumed — "Unable to set control(s) error_idx=2/2" no longer fires.

# 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.
