Included in video.js 7 by default! See the [video.js 7 blog post](https://blog.videojs.com/video-js-7-is-here/) Maintenance Status: Stable Video.js Compatibility: 6.0, 7.0 <!-- START doctoc generated TOC please keep comment here to allow auto update --> <!-- DON'T EDIT THIS SECTION, INSTEAD RE-RUN doctoc TO UPDATE --> **Table of Contents** *generated with [DocToc](https://github.com/thlorenz/doctoc)* - [Installation](#installation) - [NPM](#npm) - [CDN](#cdn) - [Releases](#releases) - [Manual Build](#manual-build) - [Contributing](#contributing) - [Troubleshooting](#troubleshooting) - [Talk to us](#talk-to-us) - [Getting Started](#getting-started) - [Compatibility](#compatibility) - [Via MSE](#via-mse) - [Native only](#native-only) - [Flash Support](#flash-support) - [DRM](#drm) - [Documentation](#documentation) - [Options](#options) - [How to use](#how-to-use) - [Initialization](#initialization) - [Source](#source) - [List](#list) - [withCredentials](#withcredentials) - [handleManifestRedirects](#handlemanifestredirects) - [useCueTags](#usecuetags) - [overrideNative](#overridenative) - [blacklistDuration](#blacklistduration) - [bandwidth](#bandwidth) - [useBandwidthFromLocalStorage](#usebandwidthfromlocalstorage) - [enableLowInitialPlaylist](#enablelowinitialplaylist) - [limitRenditionByPlayerDimensions](#limitrenditionbyplayerdimensions) - [smoothQualityChange](#smoothqualitychange) - [allowSeeksWithinUnsafeLiveWindow](#allowseekswithinunsafelivewindow) - [customTagParsers](#customtagparsers) - [customTagMappers](#customtagmappers) - [cacheEncryptionKeys](#cacheencryptionkeys) - [Runtime Properties](#runtime-properties) - [hls.playlists.master](#hlsplaylistsmaster) - [hls.playlists.media](#hlsplaylistsmedia) - [hls.systemBandwidth](#hlssystembandwidth) - [hls.bandwidth](#hlsbandwidth) - [hls.throughput](#hlsthroughput) - [hls.selectPlaylist](#hlsselectplaylist) - [hls.representations](#hlsrepresentations) - [hls.xhr](#hlsxhr) - [hls.stats](#hlsstats) - [Events](#events) - [loadedmetadata](#loadedmetadata) - [HLS Usage Events](#hls-usage-events) - [Presence Stats](#presence-stats) - [Use Stats](#use-stats) - [In-Band Metadata](#in-band-metadata) - [Segment Metadata](#segment-metadata) - [Hosting Considerations](#hosting-considerations) - [Known Issues](#known-issues) - [Fragmented MP4 Support](#fragmented-mp4-support) - [Testing](#testing) - [Debugging](#debugging) - [Release History](#release-history) - [Building](#building) - [Development](#development) - [Tools](#tools) - [Commands](#commands) <!-- END doctoc generated TOC please keep comment here to allow auto update --> ## Installation ### NPM To install `videojs-http-streaming` with npm run ```bash npm install --save @videojs/http-streaming ``` ### CDN Select a version of VHS from the [CDN](https://unpkg.com/@videojs/http-streaming/dist/) ### Releases Download a release of [videojs-http-streaming](https://github.com/videojs/http-streaming/releases) ### Manual Build Download a copy of this git repository and then follow the steps in [Building](#building) ## Contributing See [CONTRIBUTING.md](/CONTRIBUTING.md) ## Troubleshooting See [our troubleshooting guide](/docs/troubleshooting.md) ## Talk to us Drop by our slack channel (#playback) on the [Video.js slack][slack-link]. ## Getting Started This library is included in video.js 7 by default, if you are using an older version of video.js then get a copy of [videojs-http-streaming](#installation) and include it in your page along with video.js: ```html <video-js id=vid1 width=600 height=300 class="vjs-default-skin" controls> <source src="https://example.com/index.m3u8" type="application/x-mpegURL"> </video-js> <script src="video.js"></script> <script src="videojs-http-streaming.min.js"></script> <script> var player = videojs('vid1'); player.play(); </script> ``` Check out our [live example](https://jsbin.com/gejugat/edit?html,output) if you're having trouble. Is it recommended to use the `<video-js>` element or load a source with `player.src(sourceObject)` in order to prevent the video element from playing the source natively where HLS is supported. ## Compatibility ### Via MSE - Chrome - Firefox - Internet Explorer 11 Windows 10 or 8.1 Using the [overrideNative](#overridenative) option - Chrome Android - Edge ### Native only - Mac Safari - iOS Safari ### Flash Support This plugin does not support Flash playback. Instead, it is recommended that users use the [videojs-flashls-source-handler](https://github.com/brightcove/videojs-flashls-source-handler) plugin as a fallback option for browsers that don't have a native [HLS](https://caniuse.com/#feat=http-live-streaming)/[DASH](https://caniuse.com/#feat=mpeg-dash) player or support for [Media Source Extensions](http://caniuse.com/#feat=mediasource). ### DRM DRM is supported through [videojs-contrib-eme](https://github.com/videojs/videojs-contrib-eme). In order to use DRM, include the videojs-contrib-eme plug, [initialize it](https://github.com/videojs/videojs-contrib-eme#initialization), and add options to either the [plugin](https://github.com/videojs/videojs-contrib-eme#plugin-options) or the [source](https://github.com/videojs/videojs-contrib-eme#source-options). Detailed option information can be found in the [videojs-contrib-eme README](https://github.com/videojs/videojs-contrib-eme/blob/master/README.md). ## Documentation [HTTP Live Streaming](https://developer.apple.com/streaming/) (HLS) has become a de-facto standard for streaming video on mobile devices thanks to its native support on iOS and Android. There are a number of reasons independent of platform to recommend the format, though: - Supports (client-driven) adaptive bitrate selection - Delivered over standard HTTP ports - Simple, text-based manifest format - No proprietary streaming servers required Unfortunately, all the major desktop browsers except for Safari are missing HLS support. That leaves web developers in the unfortunate position of having to maintain alternate renditions of the same video and potentially having to forego HTML-based video entirely to provide the best desktop viewing experience. This project addresses that situation by providing a polyfill for HLS on browsers that have support for [Media Source Extensions](http://caniuse.com/#feat=mediasource). You can deploy a single HLS stream, code against the regular HTML5 video APIs, and create a fast, high-quality video experience across all the big web device categories. Check out the [full documentation](docs/README.md) for details on how HLS works and advanced configuration. A description of the [adaptive switching behavior](docs/bitrate-switching.md) is available, too. videojs-http-streaming supports a bunch of HLS features. Here are some highlights: - video-on-demand and live playback modes - backup or redundant streams - mid-segment quality switching - AES-128 segment encryption - CEA-608 captions are automatically translated into standard HTML5 [caption text tracks][0] - In-Manifest WebVTT subtitles are automatically translated into standard HTML5 subtitle tracks - Timed ID3 Metadata is automatically translated into HTML5 metedata text tracks - Highly customizable adaptive bitrate selection - Automatic bandwidth tracking - Cross-domain credentials support with CORS - Tight integration with video.js and a philosophy of exposing as much
