JSPM – cdnbye@0.1.2

Package Exports

cdnbye

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (cdnbye) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

It's time to say bye to CDN.

中文

This JS library implements WebRTC datachannel to scale live/vod video streaming by peer-to-peer network using bittorrent-like protocol. The forming peer network can be layed over other CDNs or on top of the origin server. Powered by hls.js, it can play HLS on any platform with many popular HTML5 players such as video.js, Clappr and Flowplayer.

This library is a part of CDNBye project which attempts to deliver high quality video streams, decreasing the number of requests to CDN servers, reducing the cost of transmission and enhancing system’s scalability. As the name suggests, CDNBye will help you offload bandwidth from expensive traditional CDNs，while also maximizing a user’s viewing experience.

Getting Started

Quick Start Demo

Put the quick-start.html in your web page, run it. Wait for a few seconds，then open the same page from another browser. Now you have a direct P2P connection between two browsers without plugin! The first web peer will serve as a seed, if no one else in the same channel.

Integrate to Your Hls.js Project

Simply replace the hls.js script tag like:

<script src="https://cdn.jsdelivr.net/npm/hls.js@latest"></script>

with

<script src="https://cdn.jsdelivr.net/npm/cdnbye@latest"></script>

That's it!

Browser Support

WebRTC has already been incorporated into the HTML5 standard and it is broadly deployed in modern browsers. The compatibility of CDNBye depends on the browser support of WebRTC and Hls.js. Please note that iOS Safari "Mobile" does not support the MediaSource API.

Compatibility	Chrome	Firefox	Mac Safari	iOS Safari	Opera	IE	Edge
WebRTC	Yes	Yes	Yes	Yes	Yes	No	No
Hls.js	Yes	Yes	Yes	No	Yes	Yes	Yes
CDNBye	Yes	Yes	Yes	No	Yes	No	No

Installation

Pre-built Script

Include the latest version bundled with hls.js(recommended):

<script src="https://cdn.jsdelivr.net/npm/cdnbye@latest"></script>

Or include the latest version without hls.js:

<script src="https://cdn.jsdelivr.net/npm/cdnbye@latest/dist/hlsjs-p2p-engine.min.js"></script>

Via NPM

cd yourProject && npm install cdnbye --save

In your application import/require the package you want to use as the following examples:

import Hls from 'cdnbye';   // the package with hls.js

import Hls from 'hls.js';     // please run "npm install --save hls.js" first
import P2PEngine from 'cdnbye/dist/hlsjs-p2p-engine';   // the package without hls.js

Usage

Bundle

Add p2pConfig as a property of hlsjsConfig, then Create hls.js instance passing hlsjsConfig as constructor param.

var hlsjsConfig = {
    debug: true,
    // Other hlsjsConfig options provided by hls.js
    p2pConfig: {
        logLevel: 'debug',
        // Other p2pConfig options if applicable
    }
};
// Hls constructor is overriden by included bundle
var hls = new Hls(hlsjsConfig);
// Use `hls` just like the usual hls.js ...

Engine(the library without hls.js)

Create hls.js instance passsing hlsjsConfig as param. Create P2PEngine instance passing hls.js instance and p2pConfig as params. Call hls.js loadSource and attachMedia methods.

var hlsjsConfig = {
    maxBufferSize: 0,       // Highly recommended setting
    maxBufferLength: 30,    // Highly recommended setting
    liveSyncDuration: 30    // Highly recommended setting
};

var p2pConfig = {
    logLevel: 'debug',
    // Other p2pConfig options if applicable
};

var hls = new Hls(hlsjsConfig);
var p2pEngine = new P2PEngine(hls, p2pConfig);        // Key step

// Use `hls` just like your usual hls.js…
hls.loadSource(contentUrl);
hls.attachMedia(video);
hls.on(Hls.Events.MANIFEST_PARSED,function() {
    video.play();
});
