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 🙏

M3U8 视频并发下载, 并生成ffmpeg合并命令

start

npm run dev

开始使用

npm install -g m3u8-down

然后任意位置

m3u8 <url> p=6

url 必须要, p可选. p为并发下载文件数量

程序会自动解析m3u8文件并下载所有ts视频文件. 并生成一个sh脚本, 文件管理打开./temp/ ~ 下的一个.sh文件可自动合并视频, 依赖 ffmpeg

代码讲解

首先通过链家拆解获得地址携带的参数

const { origin, pathname } =  new URL(url)
const { originPath, fileName } = (url=>{
  const arr = url.split('/')
  return {
    "fileName": arr[arr.length - 1],
    "originPath": url.replace(arr[arr.length-1],'')
  }
})(pathname)

然后获取.m3u8文件, 对里面的内容进行分析

没行代码已#符号开头的代表一些协议注释, 过滤掉就是我们需要下载的视频断链接


const data = await $http.get(url)
const list = data.split('\n').filter(item=> !/^#\w+/.test(item) && item)

创建一个队列来下载任务, 通过Primise来控制下载文件, 成功一个任务就取下一个任务去下载
