@catlabtech/webcvt-backend-wasm

ffmpeg.wasm fallback backend for webcvt. Handles any format pair not covered by the native backends.

Installation

bash

npm i @catlabtech/webcvt-backend-wasm

API

Detailed API reference coming in v0.2. See the source code for now.

Notes

This backend ships a ~4 MB WebAssembly blob (a build of FFmpeg). Load it lazily when possible:

ts

async function ensureWasm() {
  const { WasmBackend } = await import('@catlabtech/webcvt-backend-wasm');
  defaultRegistry.register(new WasmBackend());
}

Requires COEP/COOP headers for multithreading. See Browser Usage.
