Forked from HyperFrames (Apache-2.0), full history preserved. Hosts are mapped explicitly and BEFORE the identifier rename, because hyperframes.heygen.com is not decoration: 175 of its occurrences are $schema identifiers that a validator dereferences. A blind rename would have left them naming a host that never serves them. The schema files are in this repo under docs/schema, so the mapped host is one we can actually serve -- that is the condition that makes the rewrite safe, and serving them is a deploy task, not an edit. docs/schema/hyperframes.json is renamed to frames.json to match the identifier it is now published under. api.heygen.com and the CLI auth against heygen.com are left UNRENAMED on purpose. They are a dependency on HeyGen's SaaS, not a name of ours to take, and the right move is to remove that integration rather than rebrand it. LICENSE and CREDITS.md are untouched; NOTICE records the lineage. Co-authored-by: Hanzo Dev <[email protected]>
hdr-hlg-regression
Regression test that locks down end-to-end HDR HLG (BT.2020 ARIB STD-B67)
video rendering. Companion to hdr-regression (PQ), kept as a separate suite
so the HLG-specific encoder/metadata path stays tested in isolation.
What it covers
| Window | Time | Shape | Expected |
|---|---|---|---|
| A | 0.0 – 2.5 s | Baseline HLG video + DOM overlay | pass |
| B | 2.5 – 5.0 s | Wrapper opacity fade around HLG video | pass |
The test pins the contract that:
extractMediaMetadatareportsbt2020/arib-std-b67/limitedfor the HLG source (i.e. HLG is detected and not silently coerced to PQ).isHdrColorSpaceflips the orchestrator into the layered HDR path on the HLG signal.- The HLG source is decoded into
rgb48leand blitted under the SDR DOM overlay on every frame. - Wrapper-opacity composition (window B) does not break HLG pass-through.
hdrEncoderwrites HEVC Main10 /yuv420p10le/ BT.2020 HLG with the correct color tags (no PQ mastering display metadata for HLG).
The suite is intentionally short (5 s, two windows) — it exists to detect
regressions in the HLG-specific code path, not to enumerate every composition
shape (those live in hdr-regression).
Fixture
src/hdr-hlg-clip.mp4 — last 5 seconds of a user-recorded HEVC HLG clip,
remuxed (no re-encode) so the HLG color tags survive verbatim.
Running
cd packages/producer
bun run test:regression hdr-hlg-regression
bun run test:regression:update hdr-hlg-regression
In CI it runs in the hdr shard alongside hdr-regression
(see .github/workflows/regression.yml).
