iter1 Phase 3: baseline measurements — Phase 2 confirmed empirically

Browse Source 
Four Phase 3 baselines captured on fresnel post-reboot 2026-05-08
00:39 CEST. SDDM watchpoint condition stayed green (greeter passed
cleanly on the new boot). All four baselines confirm Phase 2's
situation analysis empirically; one Phase 1 criterion needs minor
adjustment (Phase 3 → Phase 1 loopback per feedback_dev_process.md).

Baseline A — pre-patch failure mode (master tip 65969da):

  ffmpeg -hwaccel vaapi -i bbb_720p10s_mpeg2.ts ... under strace +
  LIBVA_TRACE captures the chain:

  vaInitialize ret = SUCCESS
  vaQueryConfigProfiles ret = SUCCESS
  vaCreateConfig(profile=VAProfileMPEG2Main, entrypoint=VLD)
    ret = VA_STATUS_ERROR_UNSUPPORTED_PROFILE

  No V4L2 ioctls beyond ENUM_FMT probes from RequestQueryConfigProfiles.
  Confirms Phase 2 Bug 1 (config.c:55-69 fall-through to default).

Baseline B — post Bug 1 scratch patch (the missing break added):

  vaCreateConfig now returns SUCCESS. V4L2 setup proceeds:
  CREATE_BUFS, QUERYBUF (40), REQBUFS, STREAMON, S_FMT, etc.
  Then VIDIOC_S_EXT_CTRLS fails:

    ioctl(/dev/video5, VIDIOC_S_EXT_CTRLS,
          {ctrl_class=0xf010000,
           count=1,
           controls=[
             {id=V4L2_CID_MPEG_VIDEO_MPEG2_SLICE_PARAMS,
              size=56, ...}
           ]})
        = -1 EINVAL

  CID 0x9909fa (V4L2_CID_MPEG_BASE+250) doesn't exist on this kernel —
  mainline removed it in favor of the split V4L2_CID_STATELESS_MPEG2_*
  CIDs. Size 56 = sizeof(combined v4l2_ctrl_mpeg2_slice_params) from
  the fork's local include/mpeg2-ctrls.h. Confirms Phase 2 Bug 2.

  Auxiliary EINVAL: src/context.c:142-155 unconditionally sets H.264
  device-wide controls (H264_DECODE_MODE, H264_START_CODE) on every
  CreateContext, regardless of profile. EINVALs on hantro-vpu-dec
  (no H.264 controls there). Intentional best-effort behavior —
  return value is cast to (void) and discarded. Auxiliary, not iter1
  scope.

Baseline C — cross-validator verbatim contract anchor:

  ffmpeg -hwaccel v4l2request strace shows ONE batched call per frame:

    ioctl(/dev/video5, VIDIOC_S_EXT_CTRLS,
          {ctrl_class=0xf010000,    // V4L2_CTRL_CLASS_CODEC_STATELESS
           count=3,
           controls=[
             {id=0xa409dc, size=12,  ...},   // SEQUENCE
             {id=0xa409dd, size=32,  ...},   // PICTURE
             {id=0xa409de, size=256, ...}    // QUANTISATION
           ]}) = 0

  Field-by-field decode of frame 1 (I-picture):
    SEQUENCE: 1280×720, vbv=0x151800, profile_level=0,
              chroma_format=1, flags=PROGRESSIVE
    PICTURE: back/fwd_ref_ts=0/0, flags=0x82
             (FRAME_PRED_DCT|PROGRESSIVE), f_code=0xF×4 (I-frame
             default), P_C_T=1 (I), structure=3 (FRAME),
             intra_dc_precision=0
    QUANTISATION: starts [8, 16, 16, 19, 16, 19, 22, 22, ...] —
                  canonical MPEG-2 default intra matrix in zigzag
                  scanning order.

  Frame 2 (P-picture) shows real f_code values {{1,1},{15,15}}
  and forward_ref_ts pointing to frame 1's timestamp. Confirms
  Phase 2's claim that matrices arrive in zigzag order;
  no permutation needed in the libva backend (kernel's
  hantro_mpeg2_dec_copy_qtable handles zigzag-to-raster).

  This is the iter1 contract anchor: every Phase 4 implementation
  diff must produce a structurally indistinguishable
  VIDIOC_S_EXT_CTRLS call.

Baseline D — H.264 regression check (Phase 1 criterion #5):

  T4 reference hashes match exactly with scratch Bug 1 fix installed:
    HW frame 1: f623d5f7a41697f67dd227275c6f1b21ffc257f65626d32fde8229357f8764c9
    SW frame 1: f623d5f7a41697f67dd227275c6f1b21ffc257f65626d32fde8229357f8764c9
    HW frame 2: 7d7bc6f2146dda8b2d223bba622c4b9fbe9674181ff1e02afe286b620342e0a8
    SW frame 2: 7d7bc6f2146dda8b2d223bba622c4b9fbe9674181ff1e02afe286b620342e0a8

  Bug 1 fix in isolation does not regress H.264.

Phase 1 criterion #3 needs adjustment (Phase 3 → Phase 1 loopback):

  Original wording: "mpv --hwdec=vaapi-copy ... engages the backend"
  Reality: mpv-vaapi-copy never loads libva for MPEG-2. mpv's hwdec
  policy filters MPEG-2 out before libva is touched. Zero V4L2
  ioctls, zero libva trace, silent SW fallback. Independent of
  Bug 1 fix state.

  Adjusted criterion #3 (proposed; locks alongside Phase 4 plan):
    "ffmpeg -hwaccel vaapi -i bbb_720p10s_mpeg2.ts -frames:v 2
     -f null - shows vaCreateConfig SUCCESS, no Failed to create
     decode configuration lines, no EINVAL from VIDIOC_S_EXT_CTRLS,
     exits 0 cleanly."

  mpv-driven testing moves to a follow-up task (mpv hwdec-codecs
  filter override), separate from iter1.

Other 4 Phase 1 criteria (vainfo regression, vaCreateConfig SUCCESS,
DMA-BUF GL pixel verify HW=SW, T4 H.264 regression) hold as locked.

Scratch state cleanup: scratch patch reverted, master backend
reinstalled, MPEG-2 fails again with vaCreateConfig=12 — back to
Baseline A state, no leak.

Phase 4 plan inputs:

  - Diff scope: src/config.c (1 break), src/mpeg2.c (rewrite to
    new API), include/mpeg2-ctrls.h (delete or empty). picture.c
    + context.c unchanged.
  - Contract anchor: cite verbatim from
    linux/v4l2-controls.h:1985-2105, FFmpeg
    libavcodec/v4l2_request_mpeg2.c:130-155, kernel
    drivers/media/platform/verisilicon/hantro_mpeg2.c, AND this
    document's Baseline C verbatim payload.
  - Phase 7 verification: re-run all 5 Phase 1 criteria
    (with #3 adjusted), byte-by-byte compare post-fix
    VIDIOC_S_EXT_CTRLS payload against Baseline C.

# Iteration 1 — Phase 3 (baseline measurements)
Phase 3 baselines for the iter1 MPEG-2 boolean-correctness work, captured 2026-05-08 00:39 CEST after fresnel reboot. All four baseline runs and the verbatim output anchors are in [`phase0_evidence/2026-05-07/iter1_phase3/`](phase0_evidence/2026-05-07/iter1_phase3/).
Phase 3 discipline (per `feedback_dev_process.md`): raw data leads, derived numbers are anchored to the visible tool invocation that produced them. Every "this matches Phase 2 prediction" claim cites a verbatim line from the captured trace, not a paraphrase.
## Reset context

fresnel rebooted between Phase 2 and Phase 3 (uptime 4 min explains the `No route to host` Phase 2 noted). SDDM watchpoint condition not triggered: `journalctl -u sddm -b | grep -E "(qFatal|crash|Error|fatal|SIGABRT)"` returns empty for this boot. Plasma Wayland session active on tty1, mfritsche logged in.
## Baseline A — pre-patch failure mode
**Goal**: capture the exact path that produces `vaCreateConfig: 12 (UNSUPPORTED_PROFILE)` on master tip `65969da`, before any iter1 work touches the code.

```
12 ftrace v4l2 lines (the ENUM_FMT probe events). Zero VIDIOC_S_FMT, zero REQBUFS, zero S_EXT_CTRLS, zero MEDIA_IOC_REQUEST_ALLOC. Decode never starts.
**Confirms Phase 2 Bug 1 directly**: `vaCreateConfig` returns `VA_STATUS_ERROR_UNSUPPORTED_PROFILE` for `VAProfileMPEG2Main` — the missing `break;` at `src/config.c:65-66` makes execution fall through to `default:` (line 67-68) which returns the error code we observe (`12`).
**mpv-as-driver does not reach this path**: a separate baseline run with `mpv --hwdec=vaapi-copy` instead of `ffmpeg -hwaccel vaapi` showed mpv silently fall back to SW decode without ever loading libva for MPEG-2 (no `[vaapi]` log lines, zero V4L2 ioctls, zero libva trace files). mpv's hwdec policy filters MPEG-2 out of vaapi-copy candidates before libva is touched. **Phase 1 success criterion #3 (mpv MPEG-2 engages backend) requires either an mpv config override or a different invocation path** — to be addressed in Phase 4 plan. ffmpeg-direct invocations exercise the full path.
## Baseline B — post Bug 1 patch failure mode
**Goal**: with the missing `break;` added as a Phase 3 scratch test, see what fails downstream. Predicted by Phase 2: `VIDIOC_S_EXT_CTRLS` returns `EINVAL` because the staging-era CID `V4L2_CID_MPEG_VIDEO_MPEG2_SLICE_PARAMS` (= `0x9909fa`) doesn't exist on this kernel.
**Patch applied** (scratch only, on throwaway branch `iter1-phase3-scratch`, reverted at end of Phase 3):

) = -1 EINVAL (Invalid argument)
```
- **CID** `V4L2_CID_MPEG_VIDEO_MPEG2_SLICE_PARAMS` = `V4L2_CID_MPEG_BASE+250` = `0x9909fa` — the fork's `include/mpeg2-ctrls.h:13` symbol. **The kernel doesn't recognize this CID** (mainline removed it; replaced by the split `V4L2_CID_STATELESS_MPEG2_{SEQUENCE,PICTURE,QUANTISATION}` at `0xa409dc/dd/de`).
- **size=56** matches `sizeof(struct v4l2_ctrl_mpeg2_slice_params)` from the fork's local header (combined sequence + picture + slice fields).
- **`error_idx=1`** = first (and only) control in the array failed validation.
- 6 calls visible across the 5-frame attempt — one per frame, plus one buffer-pool bring-up artefact.
**Confirms Phase 2 Bug 2 directly**: the kernel rejects the staging-era CID. The fork's UAPI is stale; rewriting `mpeg2.c` against the new split API is non-optional.
**Auxiliary EINVAL — H.264 device-init runs unconditionally on hantro**:
```
ioctl(6</dev/video5>, VIDIOC_S_EXT_CTRLS,
{ctrl_class=0,
count=2,
controls=[
{id=0xa40900 /* V4L2_CID_STATELESS_H264_DECODE_MODE */, size=0, value=1, value64=1},
{id=0xa40901 /* V4L2_CID_STATELESS_H264_START_CODE */, size=0, value=1, value64=1}
]}
=> {error_idx=2}
) = -1 EINVAL (Invalid argument)
```
Source: `src/context.c:142-155` unconditionally sets the H.264 device-wide controls (`V4L2_CID_STATELESS_H264_DECODE_MODE = FRAME_BASED`, `V4L2_CID_STATELESS_H264_START_CODE = ANNEX_B`) on every CreateContext, regardless of profile. **This is intentional** per the existing comment at `src/context.c:138-141`:
> Errors here are not fatal: not every backing driver supports both controls (e.g. cedrus may default to SLICE_BASED without exposing DECODE_MODE).
The error is silently swallowed via `(void)v4l2_set_controls(...)` (line 153 — explicit cast discards the return). For MPEG-2 on hantro-vpu-dec the call's a no-op; the EINVAL is noise in the trace, not a bug. **Out of scope for iter1**; documented as auxiliary finding.
**Verbatim ioctl summary** (post-Bug-1 path engages full V4L2 lifecycle):
```

22 ioctl(6</dev/video5>, VIDIOC_ENUM_FMT

1 ioctl(9<anon_inode:request>, MEDIA_REQUEST_IOC_QUEUE
1 ioctl(6</dev/video5>, VIDIOC_S_FMT
1 ioctl(6</dev/video5>, VIDIOC_QUERYCAP
```
The buffer-pool bring-up + per-frame plumbing (CREATE_BUFS, QUERYBUF, REQBUFS, STREAMON, REQUEST_ALLOC, QBUF, DQBUF, REQUEST_IOC_QUEUE) all succeeds. **Only the codec-specific control submission is broken**. This bounds the iter1 fix scope sharply.
## Baseline C — cross-validator verbatim contract anchor
**Goal**: extract the exact byte-level `VIDIOC_S_EXT_CTRLS` payload that the working independent V4L2 client (ffmpeg's `-hwaccel v4l2request`) submits per MPEG-2 frame. This is the contract Phase 4 implementation must match.
**Invocation** (verbose strace decoding compound `v4l2_ext_control` payloads):
```bash
strace -ff -tt -y -v -e trace=ioctl \
-o /tmp/iter1_phase3/baseline_C_xvalidator/ffmpeg.strace \

```

```

| `p\27\0\0\0\0\0\0` | `0x1770` ns = 6000 (matches the I-frame's timestamp) | `forward_ref_ts` (refers to frame 1) |

`QUANTISATION` (256 bytes = 4 × 64 bytes):
```
intra_quantiser_matrix[64] = [8, 16, 16, 19, 16, 19, 22, 22, 22, 22, 22, 22, 26, 24, 26, 27, 27, 27, 26, 26, 26, 26, 27, 27, 27, 29, 29, 29, 34, 34, 34, 29, ...]
```
This is the canonical MPEG-2 default intra matrix in zigzag scanning order — `8` is at zigzag-position 0 (DC coefficient), `16,16` at positions 1-2 (first AC pair). Confirms the kernel-doc claim that matrices arrive **in zigzag scanning order** (`linux/v4l2-controls.h:2076-2084`).
The remaining 192 bytes (non-intra, chroma_intra, chroma_non_intra) all start with `\20\20...` = 16,16,... — MPEG-2 default non-intra is a flat 16 matrix; chroma matrices duplicate luma when chroma_format=4:2:0.
**This is the iter1 contract anchor**: every Phase 4 implementation diff and Phase 7 verification must produce a `VIDIOC_S_EXT_CTRLS` call that's structurally indistinguishable from this — `count=3`, `ctrl_class=V4L2_CTRL_CLASS_CODEC_STATELESS=0xf010000`, the three CIDs in this order, with sizes 12 / 32 / 256 and the per-frame field values matching what VAAPI's `VAPictureParameterBufferMPEG2` and `VAIQMatrixBufferMPEG2` carry for the same fixture.
## Baseline D — H.264 regression check (Phase 1 success criterion #5)
**Goal**: prove Bug 1 fix in isolation doesn't break H.264. Re-runs T4's reference incantation against `bbb_1080p30_h264.mp4` with the scratch backend installed; expects byte-identical SHA-256 hashes against T4's reference values (`f623d5f7…` for frame 1, `7d7bc6f2…` for frame 2 at +30s seek).
**Verbatim hash output**:
```

```
Pass: HW frame 1 == SW frame 1 == T4 reference; HW frame 2 == SW frame 2 == T4 reference. Bug 1 fix in isolation does not regress H.264.
## Scratch state cleanup
After Baseline D, the scratch patch was reverted to keep master clean for Phase 4 work:
```
$ git checkout -- src/config.c
$ ninja -C build && sudo ninja -C build install
$ git branch -D iter1-phase3-scratch # branch was empty — patch was uncommitted
```
**Sanity check** (master backend reinstalled, MPEG-2 should fail again):
```
$ ffmpeg -hwaccel vaapi -i bbb_720p10s_mpeg2.ts -frames:v 2 -f null -
[mpeg2video] Failed to create decode configuration: 12 (the requested VAProfile is not supported).
[mpeg2video] Failed setup for format vaapi: hwaccel initialisation returned error.
```
Back to Baseline A state — scratch state successfully cleaned.
## What Phase 3 confirms / refutes from Phase 2
| Phase 2 claim | Phase 3 evidence | Status |
|---|---|---|
| Bug 1: `RequestCreateConfig` rejects MPEG-2 via fall-through to `default:` returning `VA_STATUS_ERROR_UNSUPPORTED_PROFILE` | Baseline A libva trace shows `vaCreateConfig ret = VA_STATUS_ERROR_UNSUPPORTED_PROFILE` for `profile=VAProfileMPEG2Main` | ✅ confirmed |
| Bug 1 fix is sufficient to advance past `vaCreateConfig` | Baseline B libva trace shows `vaCreateConfig ret = VA_STATUS_SUCCESS` post-patch | ✅ confirmed |

| mpv-as-driver engages the libva backend for MPEG-2 | Baseline A's mpv variant: zero V4L2 ioctls, zero libva trace, silent SW fallback | ❌ **refuted** — mpv silently bypasses vaapi for MPEG-2; Phase 1 criterion #3 needs adjustment |
## Phase 1 criterion #3 needs adjustment (Phase 3 → Phase 1 loopback)
Per `feedback_dev_process.md`'s Phase 3 → Phase 1 loopback edge:
> If baseline reveals the Phase 1 metric was tracking the wrong thing → loop back to Phase 1 with the corrected target.
The Phase 1 lock specified:
> 3. End-to-end decode engages the backend. `mpv --hwdec=vaapi-copy --frames=2 --vo=null --no-audio …` logs the `[vaapi] libva: Trying to open …` chain, the `Using hardware decoding (vaapi-copy)` confirmation, and exits 0 with no `Failed to create decode configuration` lines.
Phase 3 baseline shows mpv-vaapi-copy **never engages libva for MPEG-2** in the current configuration — neither pre-patch nor post-Bug-1-patch produces `[vaapi]` log lines or VA-API ioctls when invoked via mpv on the MPEG-2 fixture. The mpv hwdec policy (or ffmpeg-mpv glue layer) filters MPEG-2 out before libva is touched. So the Phase 1 criterion #3 wording can never be satisfied via the original incantation, regardless of whether iter1 fixes the libva backend.
**Adjusted Phase 1 criterion #3** (proposed; locks alongside Phase 4 plan):
> 3. End-to-end decode engages the backend. `ffmpeg -hwaccel vaapi -i bbb_720p10s_mpeg2.ts -frames:v 2 -f null - 2>&1` (with the v4l2_request env vars set) shows the `[VAAPI] libva: Trying to open /usr/lib/dri/v4l2_request_drv_video.so` chain, `vaCreateConfig ret = VA_STATUS_SUCCESS`, no `Failed to create decode configuration` lines, no `EINVAL` from `VIDIOC_S_EXT_CTRLS`, and exits 0 cleanly.
The `mpv` invocation moves from criterion to optional follow-up (potentially needs an `--vd` override or a fix to mpv's hwdec-codecs filter; a separate, smaller iteration after iter1 lands).
The other four Phase 1 criteria (vainfo enumeration regression, vaCreateConfig success, DMA-BUF GL pixel verify HW=SW, T4 H.264 regression) hold as locked — no adjustment needed.
## Phase 4 plan inputs
Phase 4 plan should specify:
1. **Diff scope** (per Phase 2 `phase2_iter1_situation.md`):
- `src/config.c:55-69` — add `break;` for `VAProfileMPEG2Simple/Main` cases (3 lines).
- `src/mpeg2.c` — full rewrite against the new split API.
- `include/mpeg2-ctrls.h` — delete or empty (drop the staging-era header that masks the kernel's modern definitions).
- `src/picture.c` — no changes (verified wired correctly in Phase 2).
- `src/context.c` — no changes (the H.264 device-init EINVAL is auxiliary, by-design swallowed).
2. **Contract anchor** (per Phase 6 contract-before-code per `feedback_dev_process.md`):
- Cite verbatim from `linux/v4l2-controls.h:1985-2105` — the three control struct definitions and flag constants.
- Cite verbatim from FFmpeg `libavcodec/v4l2_request_mpeg2.c:130-155` — the batched submission shape (3 controls, `ctrl_class=V4L2_CTRL_CLASS_CODEC_STATELESS`).
- Cite verbatim from kernel `drivers/media/platform/verisilicon/hantro_mpeg2.c::hantro_mpeg2_dec_copy_qtable` — the kernel-side zigzag-to-raster permutation (so the libva backend doesn't double-permute).
- Cite Baseline C verbatim payload from this document (`SEQUENCE` 12 bytes, `PICTURE` 32 bytes, `QUANTISATION` 256 bytes per frame).
3. **Field mapping table** (per Phase 2 `phase2_iter1_situation.md` Bug 2 detail):
- 6 structural changes from old to new API documented.
- Source-data extraction in current `src/mpeg2.c` is sound; only destination-control-struct shape and CIDs change.
4. **Phase 7 verification harness**:
- Re-run all 5 Phase 1 boolean checks (with criterion #3 adjusted as above).
- Compare the post-fix `VIDIOC_S_EXT_CTRLS` payload byte-by-byte against Baseline C's verbatim payload — exact match expected for SEQUENCE field values; PICTURE will differ on `forward_ref_ts/backward_ref_ts` (different timestamp source) and `f_code` (real values not defaults); QUANTISATION should match exactly for the same fixture.
5. **Mpv-criterion-3 follow-up** (deferred):
- File a follow-up task to investigate why mpv-vaapi-copy filters MPEG-2 out and how to override. Out of iter1 scope.
## Phase 3 → Phase 4 close
Phase 3 baselines all four green. Phase 2 Bug 1 + Bug 2 + Bug 3 confirmed empirically. Phase 1 criterion #3 needs a minor wording adjustment (mpv → ffmpeg-direct anchor) — proposed text above; locks with Phase 4 plan if approved. Phase 4 can proceed with the contract-anchored diff scope.
