Compound patch carrying the fork's pre-Step-1 substrate, originally authored by Jernej Škrabec / fourier on top of bootlin'sa3c2476: - src/h264.c + src/picture.c: V4L2_CID_MPEG_VIDEO_H264_* renamed to V4L2_CID_STATELESS_H264_*, struct shapes tracked to mainline (V4L2_CID_STATELESS_H264_DECODE_MODE/_START_CODE added to the passthrough shim). - include/hevc-ctrls.h: redirect shim to <linux/v4l2-controls.h> (kernel-side HEVC controls now live in the canonical UAPI header). - src/meson.build: src/h265.c / src/h265.h commented out — HEVC build path is excluded from this fork (RK3568 hantro G1/G2 has no HEVC, and the kernel-side HEVC controls have a separate rework in flight upstream). - src/tiled_yuv.S: aarch64 stub for tiled_to_planar (assembly source was sunxi-cedrus armv7-only; aarch64 needs a stub to keep the build linking). - include/h264-ctrls.h: removed (dead post-fourier — no source includes it; the passthrough shim's CID aliases live in the kernel header now). Functionally equivalent to the prior fork master commits:c1f5108V4L2_PIX_FMT_H264_SLICE rename4ccbfe9Strip HEVC build pathda9f2a5include/h264-ctrls.h passthrough + CID aliasesfc4bb10src/h264.c track upstream UAPI shape13e9b64src/h264.c drop num_slices field4d14ffbsrc/tiled_yuv.S aarch64 stub1b02c9bsrc/h264.c include utils.h Folded into one commit during 2026-05-04 Step 1 reconciliation (see ../phase0_evidence/2026-05-04/findings.md). Per-patch history of the early fork commits preserved on the pre-step1 branch. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
