Bumps both Arch (PKGBUILD) and Debian (build-deb.sh) sides in one commit this time — following the dual-pin lesson from PR #53. 77f9236 = libva PR #12 merge: src/av1.{c,h} implements av1_set_controls mapping VAPictureParameterBufferAV1 onto struct v4l2_ctrl_av1_sequence, queued via S_EXT_CTRLS as V4L2_CID_STATELESS_AV1_SEQUENCE. The daedalus_v4l2 daemon track will consume the ctrl to synthesise an OBU_SEQUENCE_HEADER and prepend it to the slice bitstream, so libdav1d can parse the OUTPUT buffer that ffmpeg-vaapi delivers without the sequence header. Until the daemon-side OBU synth lands (issue #11 operator track), the SEQUENCE ctrl is just sitting in the request unused. Harmless on the RK3588 vpu981 hardware path (vpu981 parses OBU bytes directly, ignores the ctrl payload). pkgver: r382.c1bb444 -> r386.77f9236 (commit count 382 -> 386, two new upstream commits: 9fa18f2 av1 + 77f9236 merge). pkgrel: 1 (fresh pkgver, no rebuild-only iteration).

# libva-v4l2-request-fourier — VA-API backend for V4L2 stateless decoders,
|
|
# multiplanar fork. Successor to the predecessor experimental package
|
|
# libva-v4l2-request-ohm-gl-fix (tarball + 18-patch stack); this package
|
|
# tracks the campaign fork's git history directly, so iteration sweeps
|
|
# (DEBUG removal, follow-up bugfixes) land in a clean linear log.
|
|
#
|
|
# Campaign: ~/src/libva-multiplanar/ (iter8 close 2026-05-06) plus
|
|
# ~/src/fresnel-fourier/ which carried the fork to iter38b — multi-device
|
|
# probe so a single libva session serves all 5 codecs (rkvdec H.264 +
|
|
# HEVC + VP9, hantro MPEG-2 + VP8) plus a bounds-check fix for
|
|
# MAX_PROFILES. Pinned below.

# Pin the fork tip. 77f9236 = PR #12 merge "av1: populate
|
|
# V4L2_CID_STATELESS_AV1_SEQUENCE in codec_set_controls (#11 libva side)"
|
|
# — addresses the libva-side portion of marfrit/libva-v4l2-request-fourier#11.
|
|
# Adds src/av1.{c,h} with av1_set_controls that maps VAAPI's
|
|
# VAPictureParameterBufferAV1.seq_info_fields onto struct
|
|
# v4l2_ctrl_av1_sequence and queues V4L2_CID_STATELESS_AV1_SEQUENCE via
|
|
# S_EXT_CTRLS. The daedalus_v4l2 daemon track is the consumer that turns
|
|
# the ctrl into an OBU_SEQUENCE_HEADER and prepends it to the slice
|
|
# bitstream so libdav1d can parse the (sequence-header-stripped) OUTPUT
|
|
# buffer that ffmpeg-vaapi delivers. Until the daemon side lands the ctrl
|
|
# is just sitting in the request unused — no-cost no-op for HW decoders
|
|
# (vpu981 parses OBU bytes directly).

# Prior pin (c1bb444) = PR #9 merge — h264_set_controls
|
|
# max_num_ref_frames fallback + libva-boundary instrumentation for the
|
|
# daedalus consumer-strict path (issue #8 libva side).
