@doedja/scenecut-core

Shared scene-detection internals. Platform-agnostic WASM (Xvid motion estimation), the detector orchestrator, the online smoother, and the file-format exporters. No I/O — you supply a FrameSource and a WasmFactory.

You probably don't want to install this directly. It ships transitively with:

• @doedja/scenecut — Node CLI + library
• @doedja/scenecut-web — browser library

This package exists so those two can share one detector implementation.

What's exported

• SceneDetector — the orchestrator. Accepts a WasmFactory + options, and a FrameSource at detection time.
• WasmBridge — thin wrapper around the emscripten module with double-buffered frames.
• SceneSmoother — online non-max suppression with a refractory gap.
• MotionWorkerPool — platform-neutral worker pool abstraction.
• installMotionHandler — the worker-side message handler you install in your worker script.
• Exporters: formatJson, formatCsv, formatAegisub, formatTimecodeList, formatEdl, formatFcpxml, formatPremiereMarkers, secondsToSmpte, frameDurationNumDen.
• Helpers: formatTimecode, calibratePCut, calculateFcode, calculateThresholds, validateFrame.

The compiled WASM is at:

• @doedja/scenecut-core/dist/detection.wasm.js (ES-module glue)
• @doedja/scenecut-core/dist/detection.wasm (binary)
