The layer of the Mattebox player without a UI: source resolution and the handler chain over the mattebox engine. For a page with its own UI. No DOM writes, except that the native handler assigns src. No side effects on import.

npm install @mattebox/player-core mattebox

import { createPlayer, matteboxHandler, nativeHandler } from '@mattebox/player-core';
import full from 'mattebox/presets/full';

const player = createPlayer(video, {
  handlers: [matteboxHandler({ preset: full }), nativeHandler()],
});

const session = await player.load({ url: 'https://example.com/vod/master.m3u8' });

The guide explains the rest.
