# Basic Usage
|
|
|
|
Basic usage of Shaka Player is very easy:
|
|
|
|
1. Start with {@tutorial welcome} and compile the library.
|
|
2. Create a simple HTML page with a video or audio element.
|
|
3. In your application's JavaScript -
|
|
1. Install Shaka's polyfills.
|
|
2. Check for browser support.
|
|
3. Create a Player object to wrap the media element.
|
|
4. Listen for errors.
|
|
5. Load a manifest.

```html
|
|
<!DOCTYPE html>
|
|
<html>
|
|
<head>
|
|
<!-- Shaka Player compiled library: -->
|
|
<script src="dist/shaka-player.compiled.js"></script>
|
|
<!-- Your application source: -->
|
|
<script src="myapp.js"></script>
|

</head>
|
|
<body>
|
|
<video id="video"

|
|

|

|

|
|
```
|
|
|
|
```js
|
|
// myapp.js
|
|
|
|
const manifestUri =
|
|
'https://storage.googleapis.com/shaka-demo-assets/angel-one/dash.mpd';
|
|
|
|
function initApp() {
|
|
// Install built-in polyfills to patch browser incompatibilities.
|
|
shaka.polyfill.installAll();
|
|
|
|
// Check to see if the browser supports the basic APIs Shaka needs.
|
|
if (shaka.Player.isBrowserSupported()) {
|
|
// Everything looks good!
|
|
initPlayer();
|
|
} else {
|
|
// This browser does not have the minimum set of APIs we need.
|
|
console.error('Browser not supported!');
|
|
}
|
|
}
|
|
|
|
async function initPlayer() {
|
|
// Create a Player instance.
|
|
const video = document.getElementById('video');
|
|
const player = new shaka.Player();
|
|
await player.attach(video);
|
|
|
|
// Attach player to the window to make it easy to access in the JS console.
|
|
window.player = player;
|
|
|
|
// Listen for error events.
|
|
player.addEventListener('error', onErrorEvent);
|
|
|
|
// 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 (e) {
|
|
// onError is executed if the asynchronous load fails.
|
|
onError(e);
|
|
}
|
|
}
|
|
|
|
function onErrorEvent(event) {
|
|
// Extract the shaka.util.Error object from the event.
|
|
onError(event.detail);
|
|
}
|
|
|
|
function onError(error) {
|
|
// Log the error.
|
|
console.error('Error code', error.code, 'object', error);
|
|
}
|
|
|
|
document.addEventListener('DOMContentLoaded', initApp);
|
|
```
|
|
|
|
That's it!
