## What is it?
|
|
|
|
An easy-to-use stream-based toolkit that you can use for media processing. All the features provided have predictable
|
|
abstractions and join together coherently.
|
|
|
|
```js
|
|
// This example will demux and decode an Opus-containing OGG file, and then write it to a file.
|
|
const prism = require('prism-media');
|
|
const fs = require('fs');
|
|
|
|
fs.createReadStream('./audio.ogg')
|
|
.pipe(new prism.opus.OggDemuxer())
|
|
.pipe(new prism.opus.Decoder({ rate: 48000, channels: 2, frameSize: 960 }))
|
|
.pipe(fs.createWriteStream('./audio.pcm'));
|
|
```
|
|
|
|
The example above can work with either a native or pure JavaScript Opus decoder - you don't need to worry about changing
|
|
your code for whichever you install.
|
|
|
|
- FFmpeg support (either through npm modules or a normal installation)
|
|
- Opus support (native or pure JavaScript)
|
|
- Demuxing for WebM/OGG files (no modules required!)
|
|
- Volume Altering (no modules required!)
|
|
|
|
