Upstream PR #1 landed daemon-side synthesis of H.264 SPS/PPS NAL units from the V4L2 stateless control structs. This bumps the package pin so both the userspace daemon and the kernel module pick up the change in lockstep (wire protocol grew a new DAEDALUS_REQ_FLAG_H264_META bit + struct daedalus_h264_meta — kernel and daemon MUST match). Effect on Pi 5 / CM5 hosts (higgs): ffmpeg -hwaccel vaapi against H.264 sources will actually decode through the daedalus daemon instead of failing with "non-existing PPS 0 referenced". Both arch + debian packages: pkgver 0.1.0.r20.3dd0eb0 (count from git rev-list), pkgrel reset to 1 (new upstream pin). VP9 / AV1 paths unchanged.

Description: V4L2 stateless decoder shim kernel module (DKMS) — Pi 5 / CM5
|
|
Out-of-tree V4L2 m2m kernel module for the daedalus-v4l2 stack on
|
|
Raspberry Pi 5 / CM5. Registers /dev/videoNN (V4L2 stateless m2m
|
|
decoder), /dev/mediaNN (media controller with request API), and
|
|
/dev/daedalus-v4l2 (chardev bridge to the userspace daemon).
|
|
.
|
|
The actual decode happens in the userspace daemon shipped by the
|
|
daedalus-v4l2 package — this module is just the kernel-side V4L2
|
|
plumbing. Install both to actually serve VAAPI / V4L2 clients.
|
|
.
|
|
Built via DKMS against the running kernel's headers.
