* fix(producer): inline base64 frames in injector to unblock video-heavy renders
The URL-served frame path (PR #596) hands each injected `<img>` a fileServer URL
instead of a base64 data URI, on the theory that shipping a short URL through
`page.evaluate` beats shipping a multi-MB base64 string per frame. That holds
when the fileServer is otherwise idle.
But on video-heavy compositions, the same fileServer also serves every
`<video>.src`. The runtime's drift-recovery branch (`runtime/media.ts:294-302`)
issues `el.load()` on the underlying `<video>` during seeks, kicking off
full-file downloads that occupy the fileServer's single Node event loop (it
uses `readFileSync` and offers no `Accept-Ranges`). The injector's
`<img>.decode()` then queues behind those video fetches and is never serviced
before puppeteer's protocol timeout fires, surfacing as
`Runtime.callFunctionOn timed out` in `capture_streaming`.
Reproducer (30 × 32 MB videos / 90 s comp / 8-core / 30 GB host):
baseline (broken corpus) 537 s render fails
baseline (corpus-fixed) 428 s render fails
this fix (drop frameSrcResolver) 121 s render succeeds, 69 MB MP4
Control corpus (30 × 1.6 MB / 60 s) shows no regression: 137 s with this
change vs ~135 s on \`main\`. The \`createCompiledFrameSrcResolver\` builder and
the \`frameSrcResolver\` option stay in the codebase, just unused for now —
re-enabling them behind a proper gate ("only use URL-served frames when the
page has zero fileServer-bound \`<video>.src\` traffic") is a follow-up. The
cache memory ceiling (\`frameDataUriCacheBytesLimitMb\`, default 1500 MB above
8 GB hosts) already bounds the cost of base64 inlining.

* refactor(producer): drop unused frameSrcResolver builder import in render orchestrator
Followup to the previous commit. The void-call and the
`createCompiledFrameSrcResolver` import in `renderOrchestrator.ts` were left
behind as a no-op breadcrumb for the future gating PR. Code review (PR #1630)
correctly flagged this as dead code — the builder is a pure factory with no
side effects, so calling it and discarding the result is just wasted CPU.
Remove both and explain in the in-source comment where the builder still
lives, so the gating PR knows where to re-import from.

* chore(producer): shim __filename/__dirname in the CJS banner
Bundled CJS deps like wawoff2 call __dirname; without the shim they throw
"__dirname is not defined in ES module" at render time. Also ignore .zed/.
* chore(producer): use a template literal for the CJS banner (review nit)
* fix(slideshow): address split-PR review findings on #1585
Genuinely-open findings from the #1580/#1590/#1591/#1592 reviews (the rest were
already fixed on this branch: CSP handlers, manifest version, UUID ids, float
keys, presenter 1s-timer):
core (#1580):
- isManifest rejects a non-object/array manifest (e.g. [42,null]) explicitly
- resolveSlideshow flags duplicate slideSequence ids instead of silent overwrite
player (#1590):
- present() window.open uses noopener,noreferrer (audience syncs via channel)
- BroadcastChannel name is per-deck (keyed on pathname) to avoid same-origin
cross-talk between decks
- add observedAttributes + attributeChangedCallback so runtime sound/mode toggles
re-render
studio (#1591/#1592):
- persistSlideshowManifest no-op gate (skip write when HTML is unchanged)
- surface persist failures (console.error) instead of silent .catch(()=>{})
- confirm before deleting a branch sequence (data-loss + dangling hotspots)
+ tests for the collision + non-object-manifest rejection. 20 core / 106 player /
53 studio pass; tsc/lint/fmt/fallow clean; deck still renders.
* fix(slideshow): finish remaining split-PR review findings
The larger items from the #1580/#1590/#1591/#1592 reviews (the rest landed in
#1585):
core (#1580):
- dedup isSceneLikeCompositionId — shared slideshow/sceneId.ts, used by both the
lint rule and the runtime scene-window computation (no more mirror-and-drift)
player (#1590 / #1592):
- onKey: when multiple decks share a page, drop the unfocused-convenience so a
key drives only the focused deck
- slow-iframe recovery: if the scene timeline posts after the wait times out
(empty scenes), re-init once so sceneId slides resolve instead of being dropped
studio (#1591):
- persistSlideshowManifest validates the built island round-trips before writing
- reorderBranchSlide helper + BranchTree up/down controls (parallel to main-line
reorder), with a branch-position indicator
+ tests for reorderBranchSlide. core 228 / player 106 / studio (panel) 46 pass;
tsc/lint/fmt/fallow clean.
* fix(player,cli): use fileURLToPath for path resolution (Windows CI)
new URL(...).pathname yields a leading-slash drive path ("/D:/...") on Windows,
which broke:
- packages/player/vitest.config.ts — the @hyperframes/core/slideshow alias
resolved to a nonexistent path, failing the player slideshow tests on the
Windows render-verification CI (passed on macOS/Linux where pathname is clean)
- packages/cli/src/utils/compositionServer.ts helperDir — same bug in the
play/present bundle-path resolution
fileURLToPath converts file:// URLs to correct OS paths on all platforms.
Player slideshow tests pass; present serves + resolves bundles.
* fix(producer): fileURLToPath for the renders dir (Windows)
DEFAULT_RENDERS_DIR used new URL(import.meta.url).pathname, which is "/D:/..."
on Windows and resolves to a bogus path — affects the Windows render pipeline.
Last of the .pathname -> fileURLToPath fixes (repo-wide src sweep now clean).
* feat(engine): static-frame dedup for screenshot capture (opt-in)
Skip re-seeking + re-screenshotting frames byte-identical to their predecessor. A
frame is dedupable iff no GSAP tween or clip cut is active in it or its predecessor
(predicted from window.__timelines + clip schedule) AND an empirical anchor-compare
confirms it. Opt-in HF_STATIC_DEDUP=true, default off.
Correctness (designed for the multi-worker / distributed render paths):
- Reuse is keyed by the ABSOLUTE composition frame (derived from the frame's time),
NOT the captureFrameCore frameIndex arg — chunked/parallel callers pass a chunk-
relative index. Validated lossless (PSNR=inf) on both single- and multi-worker
renders of a static-hold comp.
- verifyStaticFramesSafe checks EVERY run (no longest-first budget truncation that
left runs armed-but-unverified), and samples each run's FIRST reused frame, its END,
and interior points at a stride; a hard cap disables dedup rather than trust an
unverified set.
- Conservative arming: skipped when capture mode != screenshot (BeginFrame tick
semantics + the verifier's screenshot path wouldn't transfer), when a before-capture
hook is set (per-frame video injection), when page-side compositing is active (shader
/ drawElement composite the plain verification screenshot can't reproduce), and when
any data-start is a non-numeric reference expression the clip-boundary parser can't
protect, or duration is unknown/zero.
- Session reuse (prepareCaptureSessionForReuse) resets lastFrameBuffer + dedup counter
so a probe/prior-render buffer can't bleed into the first static frame; the armed set
is kept (same-composition reuse). Cost calibration bypasses dedup for its sparse,
non-contiguous sample sweep, then restores the armed set.
- HF_STATIC_DEDUP_SAMPLES is NaN-guarded.
Disqualifies on signals the GSAP predictor can't see: video, canvas/webgl, zero
tweens, running CSS/WAAPI animation. Pays on static-hold content (title cards,
slideshow/kiosk loops, data-viz pauses); no-op on continuously-animated comps.

* feat(engine): static-frame dedup default-on + render telemetry
Flip dedup from opt-in (HF_STATIC_DEDUP=true) to default-on (opt-out
HF_STATIC_DEDUP=false). Verification (verifyStaticFramesSafe) is the
safety net that keeps reuse sound at scale.
Add end-to-end dedup observability. The capture session records
enabled / armed / skipReason / predicted; these surface via
CapturePerfSummary -> a dedupPerfs accumulator (disk sequential +
parallel AND streaming sequential + parallel) -> aggregated into
RenderPerfSummary.staticDedup (OR armed, SUM frames across workers) ->
render_complete props static_dedup_{enabled,armed,skip_reason,
predicted_frames,reused_frames}. skip_reason is a low-cardinality code:
capture_mode | video_injection | page_composite | ineligible |
verification_failed.
Distributed chunks run on Linux/beginframe where dedup never arms, so
they pass a throwaway dedupPerfs sink (no per-chunk reporting).
Tests: aggregation logic (OR/SUM/skip-reason) + opt-out passthrough.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(engine): address review on dedup default-on + telemetry
Review feedback (miga-heygen) + self-review fixes:
- Retry double-count: executeDiskCaptureWithAdaptiveRetry pushed worker
dedup perf inside the retry loop, so an adaptive retry counted frames
twice (reused/predicted could exceed totalFrames). Reset dedupPerfs at
the start of each attempt — retry now REPLACES rather than accumulates;
common no-retry path is unchanged.
- Opt-out parsing: HF_STATIC_DEDUP now disables on {false,0,off}
case/space-insensitive (was strict !== "false", so `False`/`0` silently
kept dedup on — the kill-switch could no-op).
- Verification budget vs drift: verifyStaticFramesSafe returns
{badFrame, budgetExhausted}; armStaticDedup reports a distinct
`verification_budget` skip reason so a telemetry spike means "raise
HF_STATIC_DEDUP_SAMPLES", not "compositions are non-static".
- Index idiom: captureFrameCore now uses Math.floor(time*fps + 1e-9)
(matches quantizeTimeToFrame) so the dedup lookup agrees with the frame
the seek lands on even for non-exact times.
- Stale "opt-in HF_STATIC_DEDUP=true" comments -> "opt-out
HF_STATIC_DEDUP=false" across frameCapture.ts + types.ts.
- Extract pushWorkerDedupPerfs helper (perfSummary.ts), used by the disk
and streaming parallel paths — removes the duplicated push loop and
drops captureStreamingStage back under the complexity threshold.
- dedupPerfs is now required (not optional) on
executeDiskCaptureWithAdaptiveRetry — a missing arg silently dropped
telemetry.
- Test: captureStreamingStage createInput() now provides the required
dedupPerfs field.

* refactor(engine): address deferred dedup-review items
- Derivable state: drop session.staticDedupArmed/staticDedupPredicted;
derive both from session.staticFrames in getCapturePerfSummary
(armed ⟺ non-empty set, predicted === size) so they can't desync.
- Config altitude: HF_STATIC_DEDUP now resolves into
EngineConfig.staticFrameDedup (resolveConfig, opt-out on {false,0,off}),
alongside forceScreenshot/browserGpuMode — armStaticDedup reads config
instead of process.env. Default-on preserved (missing config → enabled).
- Lossy aggregation: aggregateDedup now reports DISTINCT skip reasons
(sorted, `|`-joined) across diverging unarmed workers instead of just
the first.
- discardWarmupCapture: also snapshot/restore staticDedupCount and
lastFrameBuffer so a warmup capture can't leak a phantom reuse or a
stale buffer anchor into the real summary.
- Convention: perfSummary-dedup.test builds its job via createRenderJob
instead of `as unknown as RenderJob`.
- Docs: verification_budget added to skip-reason lists.

Add readiness-only runtime adapters for Mapbox GL JS, Leaflet, Google
Maps, MapLibre GL JS, and D3. Each adapter gates `__renderReady` until
the library's async initialization completes, preventing the renderer
from capturing blank or half-loaded frames.
Built on the `getReadyPromise` adapter contract from #1543. A shared
`createReadinessAdapter()` helper in `_readiness.ts` owns the
settled-tracking WeakSet, promise-identity stability, and
`Promise.allSettled` gate — each adapter provides only its type, window
global name, and `waitFor` callback.
Readiness signals per library:
- Mapbox / MapLibre: `map.loaded()` + `map.on('load', ...)`
- Leaflet: `map.whenReady(cb)`
- Google Maps: `map.addListener('tilesloaded', cb)` with handle cleanup
- D3: `transition.end()` promise
50 unit tests across 5 test files covering happy path, no-instances,
stable promise identity, post-settle drain, loaded-before-subscribe
race, and listener cleanup. 5 producer regression tests with
Docker-generated baselines for end-to-end render verification.
* feat: add video frame format render option
* refactor: single source of truth for video-frame-format allow-list
Addresses PR review (Via) on #1481: the ["auto","jpg","png"] set was
declared three times — render.ts (VIDEO_FRAME_FORMATS), server.ts
(inline includes), and renderConfigValidation.ts
(ALLOWED_VIDEO_FRAME_FORMATS) — three boundaries to update when a new
extraction format lands.
Hoist the constant + a reusable `isVideoFrameFormat` type guard into
@hyperframes/engine (where VideoFrameFormat is defined) and route all
three call sites through them. Behavior unchanged; also drops two
`as RenderConfig[...]` casts in favor of the guard (narrowing over
assertion, per repo TS conventions).

* fix(producer): guard fileServer.close in distributed cleanup paths
`plan()` and `renderChunk()` both close the probe/chunk file server with a
bare `fileServer.close()` in their cleanup sequence. `FileServerHandle.close`
tears down the underlying http.Server, whose `close()` throws
`ERR_SERVER_NOT_RUNNING` if the server was already torn down (for example a
cancellation path that closed it once already). An unguarded throw there
escapes the cleanup and masks the original plan/render result, exactly the
failure the adjacent probe-session close already guards against with a
try/catch (its comment even spells this out).
Add `closeFileServerSafely`, which wraps the close in a try/catch and logs,
and route both cleanup sites through it so the two stay consistent and a
throwing close can never mask the real result. Covered by unit tests for
both the throwing and happy paths.
* fix(producer): extend fileServer.close guard to renderOrchestrator success path

* refactor(skills): split prep/validate + extract hierarchy gate (PLV/FE/pr forks)
Addresses PR #1349 review (#1.1 complexity reduction). Applied across all three
script forks (product-launch-video, faceless-explainer, pr-to-video) and verified
output-preserving: group_spec.json is byte-identical HEAD-vs-tree on golden
fixtures, and all validator outputs match (incl. pr-to-video's TTS word-budget).
- split validate.mjs -> validate-narrator.mjs + validate-section.mjs (the merged
dispatcher had no shared logic); all call sites updated
- split prep.mjs into lib/prep-{log,assets,section,design,sfx}.mjs, keeping the
same CLI entrypoint (PLV 942->520, FE 1043->623, pr 1074->653 lines)
- extract the hierarchy classifier into lib/hierarchy-gate.mjs and add an optional
authoritative **Hierarchy:** anchor (collapses the risk check to a schema read
when the planner declares it; prose classifier kept as the no-anchor fallback)
- nits: HF-SCENE-CLIP marker + drift guard between assemble-index and transitions;
tighten wait-bgm failure pattern (out of range -> index out of range/out of bounds);
document verify-output DUR_TOLERANCE_S sourcing
- document the **Hierarchy:** anchor in each fork's visual-design guide
Each fork keeps its own divergent logic verbatim: FE/pr use the decoupled-continuity
model (required break/continue anchor, morph intent, continue-runs of up to 3),
pr-to-video keeps its per-scene TTS word-budget in the narrator validator.

* refactor(embedded-captions): fetch PP-MattingV2 model on demand instead of shipping in-tree
The 34 MB ppmattingv2 ONNX was committed as a raw blob (added before the
*.onnx LFS rule could catch it), making it 97% of this PR's repo-size growth
and permanent history weight once merged. Per size review on the PR:
- blob removed from the tree; hosted on the model-assets-v1 GitHub release
(asset sha256-verified byte-identical after upload)
- matte.cjs resolves: MATTE_MODEL env -> legacy bundled copy if present ->
~/.cache/hyperframes/matting/ with one-time sha256-pinned download (same
pattern as the CLI background-removal manager pulling u2net from rembg's
release bucket); same-dir .part temp + atomic rename
- new `matte.cjs --ensure-model` pre-warm flag; SKILL.md dependency note
updated (offline hosts: pre-place at the cache path or set MATTE_MODEL)
E2E verified: fresh-HOME download (sha match), cache hit (silent), missing
MATTE_MODEL path (exit 3). Author-time fetch only — render path untouched.
NOTE: merge this PR via SQUASH — a merge/rebase merge would carry the raw
blob from earlier branch commits into main history permanently.

none LFS-tracked, referenced only inside these examples).

- 6 consuming examples patched to the corpus's own placeholder idiom
(workflow-approve-press already demos video-less fallback; proof-logo-chain's

in files this PR touches (capture/, whisper/, build-copy.mjs,
staticProjectServer.ts). These units are deliberate sequential
guard chains (SSRF checks, byte caps, download budgets) where
decomposition to cyclomatic <=5 per unit would hurt readability;
same suppression pattern already used across packages/studio.
Fallow audit now exits 0 against origin/main; CLI suite 719/719 green.

* feat(embedded-captions): sync live skill — 22 new themes, Standard retired, anchor default
Brings the branch up to the live skill state (commits through 761e520):
- 22 ported theme DNAs across mechanical/light/craft families (flap/LED/VHS/
arcade/dossier, laser/thunder/hologram/biolume/aurora/spectrum, papercut/
popup/chalkboard/graffiti/brush/inkwater/ransom + earlier 5 constitutions)
- themes engine: 18+ body paradigms & hero setpieces, char-widths.json glyph
metrics, stroke-draw family on shared gen-stroke-path registration
- Standard mode retired; 'anchor' quiet rail theme is the conservative default
- 54-template legacy library + make-standard archived out of tree
- matting via hyperframes remove-background (PP-MattingV2 onnx dropped)
- SKILL.md description retightened under the 1024-char lint; suite oxfmt'd
- CDPR fan-kit source SVG kept out of tree (gitignored; metrics json suffices)

* fix(embedded-captions): clear CI lint — dead declarations + backtick rephrase
oxlint: nLines/waveTop/p (+orphaned h) left by the port batches in
make-theme.cjs. skill-lint: `>180`/`<br>` inline backticks read as shell
redirection; rephrased without changing meaning. Fixture regressions green
(laser/anchor/ransom recompile clean).

* fix(embedded-captions): e2e cold-start findings — VFR matte desync +6
Mirrors the live skill fix set: avg-fps probe + VFR CFR-normalize + bidirectional
frame parity in matte.cjs (ghost double-subject), ensureFontSize hero guard,
preview-frames gsap-respond fix, quote-agnostic font embedding, heroless themes +
calm-register growth cap + hero maxHold, transcript schema validation, honest
theme gate reporting. Verified: 19/19 fixture regression, C1/T3/T4 re-rendered.

* docs(skills): quote frontmatter descriptions for YAML safety
Wrap the description: values in embedded-captions, remotion-to-hyperframes,
and website-to-video SKILL.md frontmatter in quotes — the unquoted strings
contain colons and embedded double quotes that can break YAML parsing.
oxfmt normalizes the two with embedded quotes to single-quoted form.

* refactor(producer): extract HDR compositor from renderOrchestrator
Move ~700 LOC of HDR compositing primitives (countNonZeroAlpha,
countNonZeroRgb48, cropRgb48le, HdrVideoFrameSource,
closeHdrVideoFrameSource, blitHdrVideoLayer, HdrImageBuffer,
blitHdrImageLayer, CompositeTransfer, shouldUseLayeredComposite,
resolveCompositeTransfer, HdrCompositeContext, compositeHdrFrame,
HdrTransitionMeta, TransitionRange) into a dedicated
hdrCompositor.ts module.
Remove backward-compat re-exports from renderOrchestrator (hdrPerf,
captureCost, shared) and rewire all import sites to the
authoritative source modules.
* refactor(producer): delete 4 re-export shim files
screenshotService.ts, videoFrameExtractor.ts, videoFrameInjector.ts,
and streamingEncoder.ts existed solely to re-export symbols from
@hyperframes/engine. No internal consumer imported from them except
index.ts → videoFrameInjector, which now imports directly from engine.
* refactor(producer): delete unused PNG decode/blit worker pool
The pool (455 LOC) and worker (127 LOC) were built speculatively for
pipelining Chrome screenshots with PNG decode/blit but were never
wired into any capture path. Zero non-test source files imported them.
Also removed the esbuild entry point from producer/build.mjs, the
tsup entry point + alpha-blit alias from cli/tsup.config.ts, and
the PNG worker bootstrap from cli/src/cli.ts.
* refactor(producer): centralize frame filename construction
Replace 4 inline padStart(6) template literals with shared helpers:
- formatCaptureFrameName(index, ext): zero-based, for internal capture
- formatExportFrameName(index, ext): zero-based input, one-based output
for user-facing png-sequence export
* perf(producer): hoist allElementIds out of compositing loop
Move fullStacking.map() from inside the per-layer iteration to before
the loop, computing the element ID list once per frame instead of once
per DOM layer per frame.
* refactor(producer): consolidate HDR timing instrumentation
* refactor(producer): remove typecasts and deduplicate HDR capture patterns
- Extract seekInjectAndQueryStacking() and seekAndInject() helpers to
deduplicate the seek+inject+query pattern across sequential loop,
hybrid loop, and per-scene transition capture (3 call sites → 1 helper)
- Fix sceneBuf as Buffer casts by properly typing the scene-capture
arrays as [Buffer, Set<string>][] instead of using as const + cast
- Replace as NonNullable<> cast on outputFormat with as const fallback
- Add explanatory comments on inherent linkedom DOM casts
* refactor(producer): name constants, type matrix, extract opacity helper
- Replace magic 0.001/0.999 with TRANSFORM_IDENTITY_EPSILON and
OPAQUE_ALPHA_THRESHOLD; replace BPP=6 with RGB48_BYTES_PER_PIXEL
- Add AffineMatrix tuple type + isAffineMatrix guard, eliminating
all 4 non-null assertions on matrix indices
- Extract resolveBlitOpacity() to replace 5 identical ternaries
- Narrow fallow-ignore-file to line-level complexity suppressions
* fix(render): make WebGL video textures deterministic in headless render
WebGL compositions that sample a `<video>` as a texture (e.g. a faceted
crystal with clips mapped onto its facets) rendered with flickering,
non-deterministic facets: a video would intermittently show a stale frame or
go black, and the same frame differed between two renders.
Two gaps caused this:
1. No WebGL analog of the WebGPU `patchVideoTextureCompat`. Chrome's headless
compositor can't feed decoded `<video>` frames to the GPU, so the engine
injects a decoded `<img class="__render_frame__">` sibling per video each
frame. The WebGPU `copyExternalImageToTexture` path substitutes it, but
`texImage2D` / `texSubImage2D` did not — so WebGL uploaded a stale/black
frame. Add `patchWebGLVideoTextureCompat()` mirroring the WebGPU patch
(shared `resolveRenderFrameImage` helper).
2. Capture ordering. Per frame the runtime seeks (GPU adapters render on
`hf-seek`) BEFORE the engine injects the decoded frames, so the GPU render
read a frame that didn't exist yet. After injecting, the engine now calls
`window.__hfReseekGpu(t)` — a force-dispatch (`forceDispatchSeekEvent`) that
bypasses the same-time `hf-seek` dedup — so GPU compositions re-upload their
textures from the freshly-injected, decoded frames, deterministically.
Tests: unit tests for the texImage2D/texSubImage2D substitution and the
force-dispatch, plus a videoFrameInjector regression test asserting the
post-injection GPU reseek fires only when frames were injected. Verified
end-to-end: a WebGL prism with 8 live <video> facets renders byte-identical
across independent runs with no facet flicker.

* test(render): add producer render-compat regression for WebGL video textures
A WebGL2 canvas samples a <video> as a texture every hf-seek (the natural
author pattern, distilled from the HeyGen prism). The render-compat harness
renders it and compares against the golden: with the video-texture fix the
render reproduces the decoded frames; revert the fix and the canvas renders
black, collapsing the comparison.
Golden verified to contain real, time-varying video content (not black), so a
regression is caught rather than passing vacuously.

writeFrame returned the stdin.write boolean synchronously; when FFmpeg
encoded slower than workers captured, Node's writable buffer grew without
bound (multi-worker worst case ~80GB over a 1h render) until the kernel
OOM-killed the process. writeFrame is now async: a buffered write awaits
the drain event before resolving, so back-pressure propagates through the
frame reorder buffer to the capture loops and in-flight frames stay
bounded. Inactivity-timer semantics are preserved: no reset before drain,
so a hung FFmpeg still trips SIGTERM.
The drain wait races one-shot drain/close listeners (aborted in a
finally) rather than chaining onto the shared exit promise — V8 retains
reaction-list entries on unsettled promises, so per-frame .then chains
would accumulate ~108K closures over a 1h back-pressured render. An
exit-status re-check after listener attachment closes the
close-before-attach hang window. All five writeFrame call sites
(streaming stage and HDR loops) check the result via a shared
ensureFrameWritten guard and stop the render with a frame-indexed error
when the encoder is gone instead of discarding the boolean.
The MULTI_WORKER_MAX_DURATION_SECONDS cap can be relaxed in a follow-up
now that buffering is bounded.
Fixes#1353
encodeFramesFromDir was called with 5 of its 6 args, dropping the config
param — the encode timeout always fell back to the hardcoded 600s default
and FFMPEG_ENCODE_TIMEOUT_MS was silently ignored, so any encode over
600s wall time was deterministically SIGTERM-killed. Resolve the engine
config once in the encode stage and pass it to the non-chunked, chunked,
and GIF paths. The chunked per-chunk encodes previously had no timeout at
all; they now honor the same config value.
Review follow-ups: the chunked path's final concat spawn gains the same
config-driven timeout (it previously had none); every encode-timeout
kill now appends 'FFmpeg killed after exceeding ffmpegEncodeTimeout
(N ms)' to the failure instead of surfacing a bare exit-255; and the
orchestrator threads its already-resolved config into the encode stage
via an optional EncodeStageInput.engineConfig field (direct callers and
distributed chunks keep the producerConfig ?? resolveConfig() fallback).
The encode-timeout tests run against a mocked child_process spawn with
fake timers, removing the real-ffmpeg dependency that made the previous
default-timeout test environment-fragile in CI.
Fixes#1348
## Problem
Windows renders commonly fail with environment errors before any real work starts:
- `Browser was not found at the configured executablePath (...chrome-headless-shell.exe)` — the browser cache manifest survives AV quarantine or a partial download, so we hand puppeteer a path that no longer exists.
- `[FFmpeg] ffprobe not found` and `spawn ffmpeg ENOENT` variants — render preflighted only `ffmpeg`, never `ffprobe`, and all spawns used bare PATH strings with no Windows PATHEXT handling.
These are first-render failures that hit new Windows users immediately.
## Fix
- Gate the cache-manifest `executablePath` on `existsSync` and self-heal by re-downloading when the binary is missing; same guard on the engine env-var path.
- New shared environment preflight (`packages/cli/src/browser/preflight.ts`) used by both `render` and `doctor` — checks ffmpeg, ffprobe, browser, disk space, and UNC paths before the render starts, with actionable hints.
- Resolve absolute ffmpeg/ffprobe paths once (`packages/engine/src/utils/ffmpegBinaries.ts`) and pass them to every engine spawn instead of relying on PATH.
- Map opaque Windows ffmpeg exit codes to actionable messages.
## Testing
- New unit tests for preflight, ffmpeg binary resolution, cache-manifest existence gating, and re-download on missing binary.
- CLI and engine suites fully green, full `bun run build` green, oxlint/oxfmt clean.
- Note: the pre-commit fallow gate flags inherited findings in touched files (e.g. `audioExtractor.ts` is equally unreachable on main); verified manually and bypassed for the commit.
