Install package:
npm install @diotoborg/maxime-placeat-deserunt
# or
yarn add @diotoborg/maxime-placeat-deserunt
# or
pnpm add @diotoborg/maxime-placeat-deserunt
Import and use it:
import { parseSchema } from '@diotoborg/maxime-placeat-deserunt';
const ffmpegCommand = parseSchema(schema);
or if you need filter complex part only:
const filter = parseSchema(schema, true);
Tool translates video description from JSON to complex FFmpeg command including all required preprocessing steps, filters and transitions.
The timeline can be passed either as a JSON string or as a JS object. For example this JSON represent the timeline shown above:
