opus.js

An Opus audio decoder for aurora.js, ported using Emscripten.

Browser usage

You can either use Browserify to build your project using the Node module system, or download standalone versions of aurora.js, ogg.js, and opus.js to include as <script> tags on your HTML page.

See the Aurora.js docs for details on using Aurora.js.

Node usage

Install using npm:

npm install av opus.js

Register codecs and play a file:

var AV = require('av');
require('opus.js'); // and any other codecs you want...

AV.Player.fromFile('filename.ogg').play();

In node, requiring opus.js automatically loads the ogg.js demuxer.

See the Aurora.js docs for more details.

Building from source

1. Install Emscripten.
2. Run make to fetch and build the submodules, and to build the emscripten lib. Run this again whenever you make changes to the C wrapper or a new version of libogg is released.
3. Run make browser to generate a browser version of opus.js, or use browserify to build your application.
