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 🙏

ts to mp4,flv to mp4 mux 模块

online usage

<script src="https://cdn.jsdelivr.net/npm/vod-fp-mux@latest/lib/vod-fp-mux.min.js"></script>

or

npm install vod-fp-mux --save
import Mux from 'vod-fp-mux';

ts to mp4

const { TsToMp4 } = Mux;
const tsToMp4 = new TsToMp4();

// bind event
tsToMp4.on('data', buffer => {});
tsToMp4.on('error', e => {});

/*
 * buffer: ts buffer信息
 * sequenceNumber: 分片序列id
 * keyInfo: // aes-128加密的ts的key信息
 *    {
 *      method:'AES-128',
 *      key:,// 16字节 arraybuffer or uint8array
 *      iv:,// 16进制字符串或uint8array
 *    }
 *
 * /
tsToMp4.push(buffer,sequenceNumber,keyInfo)
tsToMp4.flush()

首次处理或者level 改变时执行 tsToMp4.resetInitSegment()

存在不连续标记时执行 tsToMp4.setDisContinuity()

seek时执行 tsToMp4.setTimeOffset(offset) // offset 当前位置在timeline上偏移
const { TsStringify } = Mux;
// demux ts 为对应的对象结构 ,使用方式如上

flv to mp4

const { FlvToMp4 } = Mux; //基本 api 同上,暂时执行 setDisContinuity()无效
const { FlvStringify } = Mux; //// demux Flv 为对应的对象结构

mp4 parser

解析 MP4 buffer 为对应的 box 树形对象结构

const { Mp4Stringify } = Mux;

let mp4Json = Mp4Stringify(buffer);
