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 🙏

dashjs-mpd-loader

用于将mpd文件内容,转化为dash.js 支持的manifest对象。可以用来实现mpd文件的预加载。

说明

将Manifest.mpd文件名转化为js对象,该对象可以直接用作dash.js player的src。从而可以在某些场景下,提前预加载mpd文件,在播放时直接使用而无需加载。

安装

umd打包,支持各种方式引入:

npm i dashjs-mpd-loader

使用

npm方式

安装

npm i dashjs-mpd-loader

加载页面

import mpdLoader from "dashjs-mpd-loader"

// 方式1:直接通过load方法加载远程mpd
mpdLoader.load(mpdSource).then(manifest => {
  // 保存manifest,在需要时使用
  // 
  window.videoManifest = manifest
})

// 方式2:通过ajax加载mpd内容,再转化为manifest对象
const mpdUrl = 'https://xxx.xxx.xxx/xxx/Manifest.mpd'  // 示例

const xhr = new XMLHttpRequest();

xhr.onload = () => {
  const baseUri = url.replace(/([^\/])+?$/, ''); // baseUri是要加载的视频分片的基础路径,一般是'https://xxx.xxx.xxx/xxx/'
  const manifest = mpdLoader.parse(xhr.responseText, baseUri);
  window.videoManifest = manifest
}

xhr.open(methods, url, true);

xhr.send();
// 在播放页面,在初始化player时使用
dashPlayer.initialize(videoElement, window.videoManifest)
// 或,在设置src时使用
dashPlayer.attachSource(window.videoManifest)

browser方式

引入script

<script src="path/to/dashjs-mpd-loader.js"></script>

使用


// 方式1:直接通过load方法加载远程mpd
DashjsMpdLoader.load(mpdSource).then(manifest => {
  // 保存manifest,在需要时使用
  // 
  window.videoManifest = manifest
})

// 方式2:通过ajax加载mpd内容,再转化为manifest对象
const mpdUrl = 'https://xxx.xxx.xxx/xxx/Manifest.mpd'  // 示例

const xhr = new XMLHttpRequest();

xhr.onload = () => {
  const baseUri = url.replace(/([^\/])+?$/, ''); // baseUri是要加载的视频分片的基础路径,一般是'https://xxx.xxx.xxx/xxx/'
  const manifest = DashjsMpdLoader.parse(xhr.responseText, baseUri);
  window.videoManifest = manifest
}

xhr.open(methods, url, true);

xhr.send();
