From 8d71e20bf738c4bc346350953f262a621dc6472a Mon Sep 17 00:00:00 2001 From: "Claude (noether)" Date: Fri, 8 May 2026 15:58:34 +0200 Subject: [PATCH] fresnel-fourier iter2 Phase 6 commit B: rewrite h265.c against new V4L2 stateless HEVC API MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Rewrites src/h265.c (407 lines → 588 lines) and the picture.c HEVC dispatch + per-slice accumulation against the modern split V4L2_CID_ STATELESS_HEVC_{SPS,PPS,SLICE_PARAMS,SCALING_MATRIX,DECODE_PARAMS, DECODE_MODE,START_CODE} stateless controls. Replaces the staging-era V4L2_CID_MPEG_VIDEO_HEVC_{SPS,PPS,SLICE_PARAMS} CIDs that were removed from the kernel UAPI. Per-frame submission: ONE batched VIDIOC_S_EXT_CTRLS, count=5, ctrl_class=V4L2_CTRL_CLASS_CODEC_STATELESS: 0xa40a90 SPS (40 bytes) 0xa40a91 PPS (64 bytes) 0xa40a92 SLICE_PARAMS (variable; dynamic-array; one entry per slice) 0xa40a93 SCALING_MATRIX (1296 bytes; memset-zero when no scaling list) 0xa40a94 DECODE_PARAMS (328 bytes; per-frame DPB info) Plus device-wide menus set once at context.c init (separate batched S_EXT_CTRLS call so a kernel without HEVC controls — e.g. hantro on RK3568/RK3399 — silently fails its batch without invalidating H.264): 0xa40a95 DECODE_MODE (FRAME_BASED on rkvdec) 0xa40a96 START_CODE (ANNEX_B on rkvdec) Reference: FFmpeg libavcodec/v4l2_request_hevc.c:505-565 (v4l2_request_hevc_queue_decode batched submission shape). Phase 5 review amendments incorporated: C1 (data_byte_offset NOT data_bit_offset): Old h265.c at lines 184-209 ran an 8-bit search to compute bit-granularity offset. New API renames the field to data_byte_offset (u32 byte offset). Bit-search dropped; replaced with plain byte offset = source_offset + slice->slice_data_byte_offset. C2 (dpb_entry.flags only LONG_TERM_REFERENCE; pic_order_cnt_val singular; poc_st_curr_*[] arrays hold DPB INDICES not POC): h265_fill_decode_params replaces old slice-params DPB iteration with explicit DPB classification + index-array population. For each VAAPI ReferenceFrames[i]: - Classify into ST_CURR_BEFORE / ST_CURR_AFTER / LT_CURR via VA_PICTURE_HEVC_RPS_* flags. - Set dpb[j].timestamp, .pic_order_cnt_val (singular), .field_pic. - Set dpb[j].flags = LONG_TERM_REFERENCE iff RPS_LT_CURR. - Append j (DPB index, u8) to poc_st_curr_before[k] / poc_st_curr_after[k] / poc_lt_curr[k] based on classification. C3 (union-aliasing reasoning corrected): BeginPicture's params.h265.num_slices = 0 reset is benign for non-HEVC profiles because byte ~17764 of the params union is past any field non-HEVC profiles read, NOT because RenderPicture's per-buffer copies overwrite that location. Wording amended in phase4_iter2_plan.md per phase5_iter2_review.md. S1 (PPS flags 19 + 20 — DEBLOCKING_FILTER_CONTROL_PRESENT and UNIFORM_SPACING): Empirically VAAPI does NOT expose either flag in the VAPictureParameterBufferHEVC pic_fields.bits or slice_parsing_fields.bits. Both bits left zero. BBB-720p10s_hevc fixture uses neither tiles nor explicit deblocking-control parameters, so the omission is correct for the iter2 binding cell. S2 (3 PPS scalars added): pic_parameter_set_id (default 0; VAAPI doesn't expose), num_ref_idx_l0_default_active_minus1, num_ref_idx_l1_default_ active_minus1 (both populated from VAAPI picture struct). Q2 (slice_segment_addr populated): Was missing in old h265.c. Now sourced from VAAPI's slice->slice_segment_address. S3 (SCALING_MATRIX content choice): Implementer choice taken: when iqmatrix_set==false (BBB has no scaling list per SPS flags = SAO|STRONG_INTRA_SMOOTHING), h265_fill_scaling_matrix sends memset-zero. Matches FFmpeg's sl=NULL pattern at v4l2_request_hevc.c:384-403 (preserves byte-equality vs cross-validator anchor). S4 (FFmpeg function name fix): cosmetic; no code impact. Plus one Phase 6 inline correction: phase 5 review S1 suggested VAAPI exposes uniform_spacing_flag in pic_fields.bits; empirical test-compile shows it doesn't. Comment added in h265_fill_pps documenting the omission. Picture.c changes (3 edits): 1. codec_set_controls HEVCMain dispatch (lines 204-206 → call h265_set_controls; replaces explicit Fourier-local: HEVC stripped reject). 2. codec_store_buffer HEVC VASliceParameterBufferType case: append VAAPI slice param to params.h265.slices[N] array, increment num_slices. Single-slice mirror at .slice retained for h265_fill_pps (which reads dependent_slice_segment_flag from LongSliceFlags). 3. RequestBeginPicture: add params.h265.num_slices = 0 reset alongside existing h264.matrix_set = false reset. Surface.h: extend params.h265 struct with slices[HEVC_MAX_SLICES_PER_ FRAME=64] array + num_slices counter. ~17 KB extra per surface union; 24 surfaces in iter7 cap_pool = ~400 KB total surface_heap growth. object_heap allocator picks up new size automatically via sizeof(struct object_surface). Context.c: separate 2-control batched call sets HEVC DECODE_MODE + START_CODE device-wide. Same best-effort (void)v4l2_set_controls pattern as the existing H.264 device-init block; if kernel doesn't advertise HEVC controls (hantro on RK3568/RK3399), the batch silently fails without invalidating the H.264 batch. Meson.build: uncomment 'h265.c' (line 50) and 'h265.h' (line 73) in sources + headers lists. H265.h: added HEVC_MAX_SLICES_PER_FRAME=64 #define before struct forward declarations. Phase 6 smoke test on fresnel (post Commit A + Commit B): Criterion 1: vainfo lists VAProfileHEVCMain on rkvdec env binding (/dev/video1 + /dev/media0). PASS. Criterion 3: ffmpeg -hwaccel vaapi HEVC decode of bbb_720p10s_hevc.mp4 -frames:v 5 -f null -, exit 0. cap_pool_init: 24 slots ready. PASS.

PASS. Criterion 5: regression hashes hold for both prior cells: H.264 +30s HW frame 1: f623d5f7a41697f67dd227275c6f1b21ffc257f65626d32fde8229357f8764c9 (T4 ref MATCH) H.264 +30s HW frame 2: 7d7bc6f2146dda8b2d223bba622c4b9fbe9674181ff1e02afe286b620342e0a8 (T4 ref MATCH) MPEG-2 +02s HW frame 1: 6e7873030dbf0403c67f35dd106ebef3c7909a0fd12433b82ad758e7fee9f092 (iter1 ref MATCH) MPEG-2 +02s HW frame 2: ccc7ce08810d4a96e9ba7a19f4f95bbf6cc861bda9337604b5c668ad52bef7de (iter1 ref MATCH) PASS. All five criteria green on first build attempt — Phase 5 review caught the 3 Critical UAPI errors (data_bit_offset → data_byte_offset rename; dpb.rps field gone + pic_order_cnt_val rename + index-array semantics) that would have been Phase 6 compile failures or silent Phase 7 byte-compare divergences. Without that review pass, this commit would have been the start of a 2+ loopback debugging cycle.
