Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

一个便利的工具,从 m3u8 转换到 mp4 文件,并且可以在浏览器端使用!

感谢

基于优秀的 FFMPEG ffmpeg.wasm,简单封装了下。

demo 演示

见 demo 文件夹下。

在线体验

安装

In Browser

<script src="https://unpkg.com/@zackdk/[email protected]/dist/m3u8tomp4.browser.mini.js"></script>

npm

npm i @zackdk/m3u8tomp4

使用

//node端
//import m3u8tomp4 from 'm3u8tomp4'; ES Module
const m3u8tomp4 = require('m3u8tomp4');
const fs = require('fs');
//返回一个promise, data 是一个 Unit8Array。
const data = await m3u8tomp4.default(m3u8Url, options);
fs.promises.writeFile('./test.mp4', data);

//浏览器内
const data = await m3u8tomp4(m3u8Url, options);
const url = URL.createObjectURL(new Blob([res.buffer], { type: 'video/mp4' }));

//log信息
m3u8tomp4.setLogger((msg) => console.log);

options

interface MergeOptions {
  /** 下载 TS 片段时,最大的并发请求数量,默认 6 */
  maxLimit?: number;
  /** 是否打印日志,默认 true */
  logOpen?: boolean;
  /** 如果下载ts片段,出现下载失败的情况,重新下载所有失败片段的次数,默认 3 */
  retryTimes?: number;
}

限制

具体请参照 ffmpeg.wasm 的FAQ.

  1. 只能在支持 SharedArrayBuffer 的浏览器种运行.(目前看来只有 PC 端的谷歌浏览器可以用)

  2. 由于 WebAssembly 的限制,最大支持 2GB 文件的输入.
