PKGBUILD pinning daedalus-v4l2 @ f04d700 (Phase 8.13 close).
Installs:
- /usr/bin/daedalus_v4l2_daemon — the FFmpeg-backed decode daemon
- /usr/libexec/daedalus-v4l2/{test_chardev_pingpong,test_m2m_decode,
test_m2m_stream} — verification harnesses
- /usr/include/daedalus_v4l2_proto.h — shared kernel↔daemon wire
protocol (for third-party chardev clients)
- /usr/share/doc/daedalus-v4l2/ — README + Phase 8.x closure docs
Runtime deps: ffmpeg (libavformat/libavcodec/libavutil dlopen'd
at runtime per Option γ — daemon binary is link-clean from
FFmpeg), libdrm.
optdepends:
- daedalus-v4l2-dkms: companion kernel module
- libva-v4l2-request-fourier: VAAPI consumer routing through us

# 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.
