opus.js's Introduction

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

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

Install Emscripten.
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.
Run make browser to generate a browser version of opus.js, or use browserify to build your application.

License

libopus is available under its existing license, and the JavaScript and C wrapper code in this repo for Aurora.js is licensed under MIT.

opus.js's Issues

Please provide also encoder

opus.js suggests you can both encode and decode signal.

Please add encoding support. Maybe create opus-decode.js for only decoding?

error when using with browserify

i've installed av and opus.js:

"av": "^0.4.9",
"opus.js": "^0.1.1",

however when i try to play it in browser i get the following error:

opus.js can't play some opus files

Hello! My android app uses OPUS to record and play audio. OPUS is not supported on most mobile browsers such as Safari and Chrome so I gave a shot with this awesome library.
I used the prebuilt opus.js and succeeded to play opus files. However, some of my files cannot be played and I have no idea why this happens on some files. I've confirmed that these files are correct opus files using opusinfo and these files can be played on VLC player as well. I've attached links that you can download.
