This is used to configure the application for a specific runtime environment. This function first creates a DashContext. Player.attachView(document.querySelector("#videoplayer")) setup the video element and attach it to the Dash player Add the following script after the line in which you load : Next, create a function to initialize the player when the page loads. To add the dash.js player to your applications, add a script tag to the head section of basicPlayer.html:

If you have a look around the dash.js repository, you find the individual files, test code and much more, but if all you want to do is use dash.js, then the file is what you need. This file is a convenience file that pulls together all the necessary dash.js code into a single file. This should be saved in the JavaScript folder of your application. To add the dash.js reference implementation to the application, you need to grab the file from the latest version of dash.js project. The first step is to create a standard HTML page containing the video element, save this file as basicPlayer.html, as the following example illustrates: Using dash.js, it really is that simple to embed MPEG-DASH video in your browser-based applications. Initializing the player can be completed in just a handful of lines of JavaScript code. View the results in a browser that implements MSE.To create a simple web page that displays a video player with the expected controls such a play, pause, rewind etc., you need to: Creating a browser-based streaming video player For more information about DASH.js, js see the GitHub dash.js repository. It provides MPEG-DASH playback in any browser that supports the W3C Media Source Extensions (MSE), today that is Chrome, Microsoft Edge, and IE11 (other browsers have indicated their intent to support MSE). Its goal is to provide a robust, cross-platform player that can be freely reused in applications that require video playback. That means that the first few seconds can be played in a fast-to-download lower quality segment and then step up to a higher quality once sufficient content has been buffered.ĭash.js is an open-source MPEG-DASH video player written in JavaScript. This ability to adapt the bandwidth required also results in a faster start time for video. As network congestion reduces, the video player will in turn return to a higher-quality stream. This reduces the likelihood of the viewer seeing a "paused" video while the player downloads the next few seconds to play (that is, it reduces the likelihood of buffering). With MPEG-DASH, the video stream adjusts automatically to a lower definition when the network becomes congested.
