fix(producer): audio drops + blank images on FFmpeg 4.x/CORS-restricted origins (#1140)
* fix(engine): remove amix normalize=0 to fix audio on FFmpeg 4.x/6.x amix's normalize=0 option is absent from many FFmpeg builds (e.g. FFmpeg 4.2 on Ubuntu 20.04). When the option is not recognized, FFmpeg fails the entire filter graph initialization, processCompositionAudio returns success:false, and the assembled video has no audio stream. Replace normalize=0 + weights='1...' with the amix default behavior (normalize=true, divides by track count) and multiply the master output gain by the track count to restore the original per-track volumes. The net volume is identical across all FFmpeg versions. Fixes #1136-adjacent: reported as 'audio doesn't play' in rendered MP4. * fix(producer): strip img crossorigin + fix audioExtractor normalize=0 Two follow-up fixes: 1. htmlCompiler: strip crossorigin attribute from <img> elements during compilation. External images (e.g. S3) with crossorigin='anonymous' force CORS-mode requests against the renderer's localhost file server, which S3 rejects → images render blank. Matches the existing video strip at line 261. 2. audioExtractor: same amix normalize=0 bug as audioMixer.ts. The audioExtractor path is used for <video data-has-audio='true'> mixing in the CLI's local render pipeline; on FFmpeg 4.x it would also drop audio silently. Fix: remove normalize=0, compensate with volume=N. * test(engine,producer): pin amix normalize contract + img crossorigin strip - audioMixer.test.ts: assert filter has no normalize=/weights=; add 3-track test confirming compensatedGain = masterGain × N = 3 - htmlCompiler.test.ts: parallel tests for img and video crossorigin strip (covers both elements, not just video) |

fix(engine): sample-accurate volume automation so dense fades keep their audio (#1117)
Animated media volume (GSAP/JS fades) dropped the audio track entirely for dense fades. The 60 Hz timeline probe emits 100-300 keyframes for a multi-second fade, which were folded into an FFmpeg `volume` expression nesting one `if(lt(t,...))` per keyframe. Past ~95 nested levels (build-dependent, lower on some Linux ffmpeg builds) the expression overflows FFmpeg's evaluator, fails filter-graph init, fails the whole mix, and the muxer omits audio — so a `data-volume="0"` fade-in rendered with no audio at all (follow-up to #1066; this is why #1064's own scenario regressed once the fade was dense enough). Apply volume automation as sample-accurate gain, layered so audio is never lost: 1. Primary: bake the envelope into the prepared PCM samples in-process (audioVolumeEnvelope.ts). The track WAV is always pcm_s16le/48k/stereo; multiply its samples by the interpolated envelope and atomically rename the result into place, then mix at unity. No expression, no keyframe ceiling, exact at every sample, and the downstream ffmpeg amix/AAC encode is untouched so golden baselines only change where a fade is applied. The RIFF parser scans chunks order-independently and accepts only 16-bit PCM, falling back otherwise. The output is written to a random-named sibling and renamed, so a crash can't leave a truncated WAV and there's no predictable-path write. 2. Fallback: RDP-bounded ffmpeg `volume` expression (0.5% tolerance, capped at 32 segments) for the rare case a WAV is not 16-bit PCM. 0.5% keeps the rendered envelope within ~0.2 dB of the source curve. 3. Backstop: if an automated mix still fails, retry once at base volume and surface the degradation rather than dropping the track. This mirrors how OSS NLEs render automation (sample-level gain): MoviePy, Kdenlive/Shotcut (MLT), Remotion. Verified end-to-end: a 297-keyframe fade that rendered with no audio now bakes all 297 keyframes sample-accurately. Adds unit tests for sample-accurate gain, track-start offset, base/tail holds, thousands of keyframes, order-independent chunk parsing, and format rejection, plus mixer regression tests for bounded nesting and the base-volume backstop. |

fix(engine,producer): URL-clamp sub-comp src paths and warn on silent extraction misses
A <video src='../assets/foo.mp4'> inside a sub-composition silently dropped from extraction; the rendered output froze on the first decoded frame for the entire clip, with no error in stdout. Root cause: browser URL resolver clamps '..' at origin root (studio preview loads fine), but path.join(projectDir, '../assets/foo.mp4') normalizes to parent-of-project/assets/foo.mp4, which usually doesn't exist. existsSync returns false, extraction is skipped, no frame lookup is built, the per-frame injector has nothing to swap, and the <video> element's first decoded frame paints every screenshot. - Adds resolveProjectRelativeSrc in videoFrameExtractor that mirrors browser clamping (literal join first, then leading '..' stripped). - Surfaces a loud stderr warning when the resolver misses. - Mirrors fix in audioMixer.ts (same bug for <audio src='../'>) and renderOrchestrator HDR probe loop. - +6 regression tests.

fix(engine,producer): preserve template-wrapped sub-composition media offsets (#476)
## Problem Template-wrapped sub-compositions could still lose correct parent timing during render in more than one place. In the validated repros, a host sub-composition starting after the intro (and in one follow-up repro, starting at `20s` after earlier compositions) contained scene-local media inside it. On the broken paths: - template-wrapped media could be missed during compile and scheduled at raw scene-local time - already-correct first-pass offsets could be clobbered during `recompileWithResolutions()` - even after those two fixes, the browser-metadata reconcile step in `executeRenderJob()` could still overwrite a compiled global `end` with a scene-local `data-end` from the inlined DOM, clipping the tail off late-start sub-composition media ## What this fixes ### Template-wrapped media discovery - `parseVideoElements`, `parseImageElements`, and `parseAudioElements` now unwrap a single top-level `<template>` wrapper before scraping media - the unwrap helper is DOM-based, not regex-based, so it avoids the CodeQL backtracking warning and only unwraps the exact single-wrapper shape we want - multiple sibling templates or other top-level content are left untouched instead of being rewritten heuristically ### Offset preservation after duration resolution - `recompileWithResolutions()` now preserves the first-pass sub-composition media arrays when the already-inlined HTML no longer contains `[data-composition-src]` hosts - that prevents correctly offset media metadata from being overwritten by scene-local media parsed from the merged DOM ### Browser metadata reconciliation in the compiled time origin - browser-discovered media can still report scene-local `data-start` / `data-end` from the merged DOM after inlining - the producer now reprojects browser `end` values into the compiled element's time origin before reconciling them back into `composition.videos` / `composition.audios` - this prevents late-start sub-composition media from getting truncated back to a scene-local end during the probe phase ### Regression coverage - adds focused engine tests for the template unwrap helper - adds producer regression coverage for both the initial compile path and the post-inline `recompileWithResolutions()` path - adds producer regression coverage for late-start host compositions (`t≈20`) with scene-local media inside them - adds producer unit coverage for the browser-end reprojection helper used by the reconcile path ## Root cause There were three distinct renderer failures behind the bug: ### 1. Template contents were invisible to the media scrapers `parseSubCompositions()` reads raw sub-composition HTML and applies the host offset to discovered media. But the engine media helpers were querying the parsed document directly, and linkedom follows browser semantics here: top-level `<template>` contents live in a `DocumentFragment`, so `querySelectorAll()` never saw those `<video>` / `<audio>` / `<img>` nodes. That meant template-wrapped sub-compositions could silently produce zero discovered media during the first pass. ### 2. The duration-resolution recompile could clobber already-correct offsets After the browser resolves composition durations, `recompileWithResolutions()` reparses the already-inlined HTML. By that point the original `[data-composition-src]` hosts are gone, so `parseSubCompositions()` legitimately returns no nested media. The old code still rebuilt the deduped media arrays from the merged DOM, which let scene-local media parsed from the inlined HTML overwrite the correctly offset first-pass metadata. ### 3. The browser probe reconcile path mixed two timing coordinate systems `discoverMediaFromBrowser()` reads `data-start` / `data-end` directly from the live DOM after sub-compositions are already inlined. For nested media, those attributes can still be scene-local even though the compiled metadata has already been offset into the parent host timeline. The old reconcile path compared those values directly and overwrote `existing.end` whenever the numbers differed. For a late-start sub-composition, that could replace a correct global end like `25.5` with a scene-local end like `5.5`, cutting the clip off during render. ## Verification ### Local checks - `bun test packages/engine/src/utils/htmlTemplate.test.ts` - `bun test packages/producer/src/services/htmlCompiler.test.ts` - `bunx vitest run packages/producer/src/services/renderOrchestrator.test.ts` - `bun run --filter @hyperframes/engine test` - `bun run --filter @hyperframes/engine typecheck` - `bun run --filter @hyperframes/producer typecheck` - `bunx oxlint packages/engine/src/utils/htmlTemplate.ts packages/engine/src/utils/htmlTemplate.test.ts packages/producer/src/services/renderOrchestrator.ts packages/producer/src/services/renderOrchestrator.test.ts packages/producer/src/services/htmlCompiler.test.ts` - `bunx oxfmt --check packages/engine/src/utils/htmlTemplate.ts packages/engine/src/utils/htmlTemplate.test.ts` - `bun run build:producer` ### Render / browser verification Verified against two local repros: 1. **Early offset repro** - host starts at `2s` - child media is scene-local `0-4s` - compiled render summary keeps the child video/audio at `start: 2` - browser verification via `agent-browser` confirmed the `2.2s` frame still shows the child clip active in the host timeline 2. **Late offset repro** - earlier compositions run first, then the target host starts at `20s` - child media starts scene-local at `1.5s` and should remain visible through `24.5s` - compiled render summary keeps the child video/audio at `start: 21.5`, `end: 25.5` - browser verification via `agent-browser` confirmed the `24.5s` frame still shows the late clip visible, which is the exact tail-clipping case the old reconcile path could break ## Notes - the `/tmp/hf-pr475-repro` and `/tmp/hf-pr476-late-offset-repro` projects plus their browser-proof artifacts are verification-only and are not part of this PR - this PR stays narrowly scoped to sub-composition media timing across compile, recompile, and browser probe reconciliation; it does not broaden into general sub-composition HTML normalization beyond the single-wrapper case |

ci(windows-render): bypass Chocolatey, fetch ffmpeg from BtbN/GitHub (#436)
## What Replace the `choco install ffmpeg` step in `windows-render.yml` with a direct download of the upstream Windows GPL build from [`BtbN/FFmpeg-Builds`](https://github.com/BtbN/FFmpeg-Builds/releases/latest) on GitHub Releases. ## Why The `Render on windows-latest` canary started failing on every PR with: ``` [NuGet] Response status code does not indicate success: 504 (Gateway Timeout). [NuGet] Response status code does not indicate success: 503 (Service Unavailable). ``` The Chocolatey community feed (`community.chocolatey.org/api/v2/package/ffmpeg/8.1.0`) is degraded for the `ffmpeg` package right now. The earlier 3-attempt retry I added wasn't enough — every attempt across multiple runs failed with 503/504, so retrying does nothing. The Chocolatey path is also a bit indirect for what this job actually validates. The real point of the canary is the [PR #336](https://github.com/heygen-com/hyperframes/pull/336) fix where `findFFmpeg()` / `where ffmpeg` discovery has to work on a fresh Windows runner. As long as `ffmpeg.exe` ends up on `PATH`, the underlying thing under test (the harness can find ffmpeg, capture frames, mux to MP4) is exercised exactly the same. BtbN/FFmpeg-Builds is the canonical upstream nightly Windows GPL build (Chocolatey itself rebundles essentially the same artifact), so this is closer to the source, not further from it. ## How - Download `ffmpeg-master-latest-win64-gpl.zip` from the BtbN release with `Invoke-WebRequest` (3-attempt retry with backoff). - Extract to `$env:RUNNER_TEMP/ffmpeg` and locate `ffmpeg.exe` recursively. - Add the bin directory to `$env:GITHUB_PATH` so all subsequent steps in the job (the Bun-driven harness, `findFFmpeg()`, etc.) see ffmpeg on `PATH` exactly the same way as before. - Print `ffmpeg -version` as a sanity check. ## Test plan - [ ] CI: `Render on windows-latest` job goes green on this PR. - [ ] Subsequent PRs no longer get blocked on `choco install ffmpeg` 503s. |

fix: remove hidden audio gain in renders (#362)
## Summary
This fixes a render-time audio correctness bug where Hyperframes applied a hidden post-mix gain to every rendered output, boosting audio by about +2.6 dB and causing clipping on normally leveled sources.
It also fixes a related mute bug where `data-volume="0"` was treated as falsy and silently converted back to full volume during audio track preparation.
Additionally, this PR fixes the Studio workspace typecheck path for `@hyperframes/player`, so local pre-commit/typecheck flows no longer depend on the Player package having been built first.
## Root Cause
The issue report measured a near-constant gain increase and suspected a hidden normalization step. After tracing the engine audio path, the root cause turned out to be explicit code, not FFmpeg behavior:
- `packages/engine/src/config.ts` defaulted `audioGain` to `1.35`
- `packages/engine/src/services/audioMixer.ts` always appended a post-mix FFmpeg filter:
- `[mixed]volume=${masterOutputGain}[out]`
- with the default config, that meant every render got multiplied by `1.35`
That exactly matches the issue reporter's measured scalar boost.
While investigating the workaround, I also found a second correctness bug:
- `processCompositionAudio()` used `element.volume || 1.0`
- that coerced `0` to `1.0`
- so `data-volume="0"` did not actually mute the track in rendered output
Separately, the repo-level Studio typecheck could fail before any build step because:
- `packages/studio/src/player/components/Player.tsx` imports `@hyperframes/player`
- `packages/player/package.json` points TypeScript at built `dist/*` outputs
- in a fresh workspace, those built outputs may not exist yet
- Studio therefore failed type resolution for `@hyperframes/player` during pre-commit/typecheck
## What Changed
1. Set the engine default `audioGain` back to unity (`1`)
2. Preserve explicit zero volumes by changing `element.volume || 1.0` to `element.volume ?? 1.0`
3. Added regression coverage for both behaviors
4. Updated the producer-side config fixture to reflect the corrected default
5. Added a Studio tsconfig path mapping for `@hyperframes/player` to the local workspace source and widened `rootDir` so workspace typecheck succeeds without requiring a prior Player build
## Why These Changes Are Needed
This is not a UX preference issue; it is a correctness and API contract issue.
- The docs describe `data-volume` as a direct 0-1 control.
- Rendered output should preserve source levels unless the author explicitly changes them.
- Hidden global gain makes output non-deterministic from the author's perspective.
- `data-volume="0"` must mean silence, not full-volume playback.
- Local workspace typecheck should not require unrelated package build artifacts to exist first.
Leaving the current behavior in place means:
- voice recordings near normal peak levels can clip during render
- authors need undocumented manual compensation (`0.75`-ish scaling) to get unity output
- mute semantics in docs and code diverge
- local pre-commit/typecheck can fail for reasons unrelated to the actual diff being committed
## Testing
### Focused regression tests
Ran:
- `packages/engine/node_modules/.bin/vitest run packages/engine/src/config.test.ts packages/engine/src/services/audioMixer.test.ts`
Result:
- `10 passed`
These tests specifically verify:
- default resolved `audioGain` is `1`
- a track with `volume: 0` stays `volume=0` in the FFmpeg filter graph
- the post-mix output filter stays at unity gain (`[mixed]volume=1[out]`)
### Broader package verification
Ran:
- `bun run --filter @hyperframes/engine test`
- `bun run --filter @hyperframes/engine build`
- `packages/engine/node_modules/.bin/vitest run packages/producer/src/services/renderOrchestrator.test.ts`
- `bun run --filter @hyperframes/producer typecheck`
- `bun run --filter @hyperframes/studio typecheck`
- `bunx oxlint packages/engine/src/config.ts packages/engine/src/config.test.ts packages/engine/src/services/audioMixer.ts packages/engine/src/services/audioMixer.test.ts packages/producer/src/services/renderOrchestrator.test.ts`
- `bunx oxfmt packages/engine/src/config.ts packages/engine/src/config.test.ts packages/engine/src/services/audioMixer.ts packages/engine/src/services/audioMixer.test.ts packages/producer/src/services/renderOrchestrator.test.ts packages/studio/tsconfig.json`
- `bunx lefthook run pre-commit`
Results:
- full engine test suite passed (`309 passed`)
- engine build passed
- touched producer test file passed (`7 passed`)
- producer typecheck passed
- studio typecheck passed
- oxlint passed with `0 warnings, 0 errors`
- formatting passed
- pre-commit hook no longer hits the prior `@hyperframes/player` module-resolution blocker
## Known Verification Limitation
There is no meaningful browser UI flow for this bug: the defect is in the engine/CLI audio render pipeline rather than an interactive browser surface. Because of that, verification was done at the renderer and test level rather than through an agent-browser flow.
## User Impact
After this change:
- rendered audio matches source level by default
- authors no longer need to compensate for a hidden +2.6 dB boost
- `data-volume="0"` correctly mutes rendered audio
- the documented volume contract matches engine behavior again
- local workspace typecheck no longer depends on prebuilt `@hyperframes/player` artifacts
Closes #361.

fix(engine): resolve external asset paths from compiled dir (#231)
## Summary
- Parent-relative paths (e.g. `src="../file.wav"`) silently drop media from rendered MP4
- The compiler rewrites external paths to `hf-ext/` and copies files to the compiled directory, but both the audio mixer and video frame extractor only resolved against `projectDir` — never finding them
- Now checks `compiledDir` first (matching the file server's resolution order), then falls back to `projectDir`
- Fixes both `<audio>` and `<video>` elements with external paths
## Real-world context
Reported in Slack by Abhai — a TTS comparison video using `<audio src="../tts-voxcpm2.wav">` (audio file in parent directory, composition in subdirectory) rendered successfully but the output MP4 had no audio stream. The render completed without any error, silently dropping the audio.
## Testing
### Environment
- Linux (Ubuntu 20.04), ffmpeg 4.2
- Test composition: `subdir/index.html` with `<audio id="bg-audio" src="../test-audio.wav">`, WAV file at parent directory
### Before fix (main)
```
[AUDIO-DEBUG] element.src=hf-ext/tmp/hf-test-231/test-audio.wav
baseDir=/tmp/hf-test-231/subdir
[AUDIO-DEBUG] resolved srcPath=/tmp/hf-test-231/subdir/hf-ext/tmp/hf-test-231/test-audio.wav
exists=false
```
- Audio mixer tries `join(projectDir, "hf-ext/...")` → file doesn't exist at that path
- Output: **9.8 KB, video stream only** (confirmed via ffprobe)
- No error logged — audio silently dropped
### After fix (this branch)
```
[AUDIO-DEBUG] element.src=hf-ext/tmp/hf-test-231/test-audio.wav
baseDir=/tmp/hf-test-231/subdir
compiledDir=/tmp/.../compiled
[AUDIO-DEBUG] fromCompiled=/tmp/.../compiled/hf-ext/tmp/hf-test-231/test-audio.wav
exists=true
[AUDIO-DEBUG] resolved srcPath=/tmp/.../compiled/hf-ext/tmp/hf-test-231/test-audio.wav
exists=true
[AUDIO-RESULT] success=true, hasAudio=true
```
- Audio mixer checks `join(compiledDir, "hf-ext/...")` first → file found
- Output: **44.6 KB, video + audio streams** (confirmed via ffprobe)
### ffprobe comparison
| Branch | File size | Streams |
|--------|-----------|---------|
| `main` | 9.8 KB | `video (h264)` only |
| `fix` | 44.6 KB | `video (h264)` + `audio (aac)` |
### Path resolution flow
1. Compiler sees `<audio src="../test-audio.wav">`
2. Compiler resolves to absolute path, maps it to `hf-ext/tmp/.../test-audio.wav`
3. Compiler copies file to `compiled/hf-ext/tmp/.../test-audio.wav`
4. Audio mixer gets `element.src = "hf-ext/tmp/.../test-audio.wav"`
5. **main**: tries `join(projectDir, src)` → not found → silent drop
6. **fix**: tries `join(compiledDir, src)` first → found → audio mixed in
### Repro
```bash
mkdir -p /tmp/test/subdir
ffmpeg -f lavfi -i "sine=frequency=440:duration=2" /tmp/test/test-audio.wav -y
# Create subdir/index.html with <audio src="../test-audio.wav" ...>
cd /tmp/test/subdir && npx hyperframes render
ffprobe -v error -show_streams output.mp4 # video only on main, video+audio on fix
```
