LIBVA-1 — when both rpi-hevc-dec and daedalus_v4l2 are loaded, finish
the per-codec dispatch so HEVC goes to rpi-hevc-dec (existing 'p'
override) and VP9 / AV1 / H.264 go to the daedalus daemon ('d').
Before this change the multi-device-probe accepted only ONE driver
plus a fixed alt slot (rkvdec↔hantro-vpu); on a Pi 5 with both decoders
the find_codec_device() walk preferred rpi-hevc-dec by known_decoder_
drivers[] order and never opened daedalus_v4l2, so VP9/AV1/H.264 frames
hit rpi-hevc-dec's S_FMT and failed.
Changes:
- request.c multi-device-probe: when primary = rpi-hevc-dec, alt =
daedalus_v4l2 (when HAVE_DAEDALUS_V4L2 is on); symmetric handling
in the daedalus_v4l2 primary branch so alt = rpi-hevc-dec. This
preserves the iter40 fallback (no daedalus → alt = NULL) when the
build option is off.
- request.c alt-driver opening block: generalized from the iter38
rkvdec/hantro pair to also dispatch into video_fd_rpi_hevc_dec and
video_fd_daedalus slots. Defensive close on unknown alt-driver
name (shouldn't happen — primary_driver branches gate the choices —
but keeps the slot tally clean if a future driver name is added
above without wiring up the dispatch here).
- request_switch_device_for_profile: added 'd' kind handler +
profile override block. When daedalus is open, VP9 / AV1 / H.264*
route to it. HEVC stays on rpi-hevc-dec via the existing 'p'
override. AV1 'a' kind (RK3588 vpu981) wins ONLY if vpu981 was
probed, so the override only fires on hosts where vpu981 stayed
-1 (i.e. Pi 5).
- RequestTerminate: close the daedalus_v4l2 fd pair on teardown
(was leaking — caught while reviewing the alt-driver expansion).
Build: meson + ninja clean on boltzmann (only pre-existing GStreamer
H265 parser noise). Behaviour on RK3399/3588 boxes unchanged — the
new branches are gated by HAVE_DAEDALUS_V4L2 *and* video_fd_daedalus
≥ 0, both of which stay false in those deployments.
Companion to daedalus-v4l2 481279c (Phase 8.13 systemd unit) and
