PackagerJS

A package that edits and packages your HLS and DASH videos

Getting Started

Make sure FFMpeg and Shaka Packager are installed and add to your path

Instalation

npm install js-stream-packager --save

Usage

const packager = require("packager")

const videopackager = new packager()
//To create DASH contents
videopackager().dash([{input:"/path/to/inputfile.mkv",duration:"59",output:'/path/to/outputfile.mp4'}],'/path/to/outputDASHManifest.mpd')

// To skip creating the steams and jump generate the manifest
// Note input files must be mp4
videopackager().dash([{input:"/path/to/inputfile.mp4",output:'/path/to/outputfile.mp4'}],'/path/to/outputDASHManifest.mpd',false)

//To create HLS contents
videopackager().hls([{input:"/path/to/inputfile.mkv",duration:"59",output:'/path/to/outputfile.mp4'}],'/path/to/outputHLSManifest.m3u8')

// To skip creating the steams and jump generate the manifest
// Note input files must be mp4
videopackager().dash([{input:"/path/to/inputfile.mp4",output:'/path/to/outputfile.mp4'}],'/path/to/outputHLSManifest.m3u8',false)

//Multiply video streams can be created to and edited with FFMPEG 
p.ffmpeg([{input:'/path/to/video.mp4',duration:'10',
size:'144x360',duration:'10',aspectRatio:'4:3',framerate:'10',output:'/path/to/outvideo.mp4'},
{input:'/path/to/video.mp4',duration:'10',startTime:'10',
size:'720x360',duration:'10',aspectRatio:'4:3',framerate:'10',output:'/path/to/video.mp4'}]
