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: Userspace daemon for the daedalus_v4l2 stateless decoder shim
|
|
daedalus-v4l2 ships the userspace daemon that backs the daedalus_v4l2
|
|
out-of-tree V4L2 kernel module on Raspberry Pi 5 / CM5. Together they
|
|
expose /dev/videoNN + /dev/mediaNN as a V4L2 stateless decoder for
|
|
VP9, AV1, and H.264 — actual decoding happens in this single-threaded
|
|
daemon via dlopen'd FFmpeg, with decoded NV12 / P010 frames shipped
|
|
back through dmabuf.
|
|
.
|
|
Consumed end-to-end by libva-v4l2-request-fourier (>= 1.0.0+r376) so
|
|
that 'ffmpeg -hwaccel vaapi' against vp9_small.ivf produces a
|
|
byte-exact NV12 frame.
|
|
.
|
|
The kernel module ships separately in daedalus-v4l2-dkms; install
|
|
both to actually serve V4L2 clients.
