* feat(studio-server): serve H.264 proxies from the preview route Wires the codec manifest and the transcoder into the preview surface: the route negotiates a proxy via a query param and serves it through the existing range and ETag machinery, composition HTML carries a codec map for the runtime, and hostile assets pre-warm so a first play does not wait on a cold transcode. Exposes the three subpath exports the CLI surfaces consume upstack. Drops the TEMP fallow entry added with the transcoder: it has real importers now. * fix(studio-server): publish media proxy exports * fix(parsers): scan HTML comments linearly * feat(cli): let projects opt out of automatic proxying Adds media.autoProxy to hyperframes.json plus --proxy/--no-proxy flags, and forwards the resolved value into the studio and preview servers and the vite adapter. Lands before the runtime slice that turns auto-proxying on, so the switch exists before there is any behavior to switch off. * fix(cli): align media config schema * feat(core): swap undecodable video to its proxy at runtime Adds the browser-side half: before first load the runtime consults the injected codec map and swaps a hostile source to its proxy, and if a video still reports zero decodable width it rescues it reactively. An HEVC file carrying AAC fires no error event, so zero videoWidth, not the error event, is the reliable signal. Audio elements and alpha sources are never proxied, render mode never proxies, and each swap evicts the element's stale sync state and reports once. This completes the loop: auto-proxying is live for preview and studio from here. The opt-out (media.autoProxy, --no-proxy) shipped in the previous slice.
@hyperframes/core
Types, parsers, generators, compiler, linter, runtime, and frame adapters for the Hyperframes video framework.
Install
npm install @hyperframes/core
Most users don't need to install core directly — the CLI, producer, and studio packages depend on it internally.
What's inside
| Module | Description |
|---|---|
| Types | TimelineElement, CompositionSpec, Asset, canvas dimensions, defaults |
| Parsers | parseHtml — extract timeline elements from HTML; parseGsapScript — parse GSAP animations |
| Generators | generateHyperframesHtml — produce valid Hyperframes HTML from a composition spec |
| Compiler | compileTimingAttrs — resolve data-start / data-duration into absolute times |
| Linter | lintHyperframeHtml — validate Hyperframes HTML (missing attributes, overlapping tracks, etc.) |
| Runtime | IIFE script injected into the browser — manages seek, media playback, and the window.__hf protocol |
| Frame Adapters | Pluggable animation drivers (GSAP, Lottie, CSS, or custom) |
Frame Adapters
A frame adapter tells the engine how to seek your animation to a specific frame:
import { createGSAPFrameAdapter } from "@hyperframes/core";
const adapter = createGSAPFrameAdapter({
getTimeline: () => gsap.timeline(),
compositionId: "my-video",
});
Implement FrameAdapter for custom animation runtimes:
import type { FrameAdapter } from "@hyperframes/core";
const myAdapter: FrameAdapter = {
id: "my-adapter",
getDurationFrames: () => 300,
seekFrame: (frame) => {
/* seek your animation */
},
};
Parsing and generating HTML
import { parseHtml, generateHyperframesHtml } from "@hyperframes/core";
const { elements, metadata } = parseHtml(htmlString);
const html = generateHyperframesHtml(spec);
Linting
import { lintHyperframeHtml } from "@hyperframes/core/lint";
const result = lintHyperframeHtml(htmlString);
// result.findings: { severity, message, elementId }[]
