Build status (CircleCI): [![CircleCI](]( [Join #dashjs on Slack!]( ## Migration from v3.x to v4.0 If you are migrating from dash.js v3.x to dash.js v4.x please read the migration document found [here]( ## Overview A reference client implementation for the playback of MPEG DASH via JavaScript and [compliant browsers]( Learn more about DASH IF Reference Client on our [wiki]( If your intent is to use the player code without contributing back to this project, then use the MASTER branch which holds the approved and stable public releases. If your goal is to improve or extend the code and contribute back to this project, then you should make your changes in, and submit a pull request against, the DEVELOPMENT branch. Read our []( file for a walk-through of the contribution process. All new work should be in the development branch. Master is now reserved for tagged builds. ## Demo and reference players All these reference builds and minified files are available under both http and https. ### Samples Multiple [dash.js samples]( covering a wide set of common use cases. ### Reference players The released [pre-built reference players ]( if you want direct access without writing any Javascript. The [nightly build of the /dev branch reference player](, is pre-release but contains the latest fixes. It is a good place to start if you are debugging playback problems. ### CDN hosted files The latest minified files have been hosted on a global CDN and are free to use in production: - [dash.all.min.js]( - [dash.all.debug.js]( In addition, all the releases are available under the following urls. Replace "vx.x.x" with the release version, for instance "v3.1.0". - []( - []( ## Documentation Full [API Documentation]( is available describing all public methods, interfaces, properties, and events. For help, join our [Slack channel](, our [email list]( and read our [wiki]( ## Tutorials Detailed information on specific topics can be found in our tutorials: * [Low latency streaming]( * [UTCTiming Clock synchronization]( * [Digital Rights Management (DRM) and license acquisition]( * [Buffer and scheduling logic]( ## Getting Started The standard setup method uses javascript to initialize and provide video details to dash.js. `MediaPlayerFactory` provides an alternative declarative setup syntax. ### Standard Setup Create a video element somewhere in your html. For our purposes, make sure the controls attribute is present. ```html ``` Add dash.all.min.js to the end of the body. ```html ... ``` Now comes the good stuff. We need to create a MediaPlayer and initialize it. ``` js var url = ""; var player = dashjs.MediaPlayer().create(); player.initialize(document.querySelector("#videoPlayer"), url, true); ``` When it is all done, it should look similar to this: ```html Dash.js Rocks
``` ### Module Setup We publish dash.js to [npm]( Examples of how to use dash.js in different module bundlers can be found in the [`samples/modules`]( directory. ### MediaPlayerFactory Setup An alternative way to build a Dash.js player in your web page is to use the MediaPlayerFactory. The MediaPlayerFactory will automatically instantiate and initialize the MediaPlayer module on appropriately tagged video elements. Create a video element somewhere in your html and provide the path to your `mpd` file as src. Also ensure that your video element has the `data-dashjs-player` attribute on it. ```html ``` Add dash.all.min.js to the end of the body. ```html ... ``` When it is all done, it should look similar to this: ```html Dash.js Rocks
``` ## Quick Start for Developers 1. Install Core Dependencies * [install nodejs]( 2. Checkout project repository (default branch: development) * ```git clone``` 3. Install dependencies * ```npm install``` 4. Build, watch file changes and launch samples page, which has links that point to reference player and to other examples (basic examples, captioning, ads, live, etc). * ```npm run start``` ### Other Tasks to Build / Run Tests on Commandline. * Build distribution files (minification included) * ```npm run build``` * Build and watch distribution files * ```npm run dev``` * Run linter on source files (linter is also applied when building files) * ```npm run lint``` * Run unit tests * ```npm run test``` * Generate API jsdoc * ```npm run doc``` ### Troubleshooting * In case the build process is failing make sure to use an up-to-date node.js version. The build process was successfully tested with node.js version 14.16.1. ### License dash.js is released under [BSD license]( ### Tested With [Browser Stack Logo](
