mpv-play-with

tampermonkey script for using local mpv player to play web videos, which requires local support for mpv-easy:// protocol

If you use mpv-easy, you only need to start mpv once, and mpv-easy will automatically register the mpv-easy:// protocol

Inspired by https://github.com/LuckyPuppy514/Play-With-MPV

install

You need to install the tampermonkey extension first

Then install script mpv-easy-play-with.user.js

npm

npm i @mpv-easy/play-with

import { sendToMpv, encodeToBase64 } from '@mpv-easy/play-with';
import type { PlayItem } from '@mpv-easy/play-with';

const list: PlayItem[] = [];
const base64 = encodeToBase64(list);
sendToMpv(base64);

type

A playable video corresponds to the following structure

export type PlayItem = {
  url: string;
  title: string;
  args: string[];
};

Encode a set of video information in base64 and pass it to the player Since the URL length is limited to 2048, zip compression is used to support more videos.

export function getMpvUrl(playList: PlayItem[]): string {
  const jsonStr = JSON.stringify(playList);
  const zipBuf = gzipSync(strToU8(jsonStr));
  const base64 = encode(zipBuf);
  return `mpv-easy://${base64}`;
}

chunk

When the data length exceeds 2048, you can use chunks to pass the data. You only need to concatenate the current chunk id and the total number of chunks after base64. To prevent errors in the order of chunk merging, it is recommended to wait 100ms after each chunk is sent to allow the program enough time to write the file.
