Configure LCEVC

LCEVC Decoder library needs to be included in the HTML page:

  • Local npm install lcevc_dec.js
<script src="../node_modules/lcevc_dec.js/dist/lcevc_dec.min.js"></script> 
  • Or use for latest LCEVC Decoder libraries.
<script src=""></script>

Configuration to enable LCEVC enhancement:

player.configure('lcevc.enabled', true); 

LCEVC setup via UI library

Sample setup using the Shaka Player UI library:

<!DOCTYPE html> 
    <!-- Shaka Player UI compiled library and default CSS for player controls: --> 
    <script src="dist/shaka-player.ui.js"></script> 
    <link rel="stylesheet" href="dist/controls.css" /> 
    <!-- LCEVC decoder compiled library --> 
    <script src=""></script>
    <!-- Application source: --> 
    <script src="app.js"></script> 
    <!-- The data-shaka-player-container tag will make the UI library place the controls in this div. --> 
    <div data-shaka-player-container style="max-width:40em"> 
      <!-- The data-shaka-player tag will make the UI library use this video element. --> 
      <video data-shaka-player id="video" style="width:100%;height:100%"></video> 
// app.js 
const manifestUri = ''; 
// Initialise Shaka Player with LCEVC enhancement. 
async function init() { 
  // When using the UI, the player is made automatically by the UI object. 
  const video = document.getElementById('video'); 
  const ui = video['ui']; 
  const controls = ui.getControls(); 
  const player = controls.getPlayer(); 
  // Enable the LCEVC enhancement. 
  player.configure('lcevc.enabled', true); 
  // Listen for error events. 
  player.addEventListener('error', onError); 
  controls.addEventListener('error', onError); 
  // Try to load a manifest. 
  // This is an asynchronous process. 
  try { 
    await player.load(manifestUri); 
    // This runs if the asynchronous load is successful. 
    console.log('The video has now been loaded!'); 
  } catch (error) { 
// Handle errors. 
function onError(error) { 
  console.error('Error', error); 
// Listen to the custom shaka-ui-loaded event, to wait until the UI is loaded. 
document.addEventListener('shaka-ui-loaded', init); 
// Listen to the custom shaka-ui-load-failed event, in case Shaka Player fails 
// to load (e.g. due to lack of browser support). 
document.addEventListener('shaka-ui-load-failed', onError); 

User provided canvas

User can also provide a canvas to the player though attachCanvas function:


Note: If external canvas is used, user is responsible for managing the canvas. If no canvas is provided for Shaka UI library, the player will generate and manage the canvas.
