# Getting Started
|
||
|
|
|
||
|
|
The important things you should take from this:
|
||
|
|
|
||
|
|
1. You install the modules you need to get the features you want - you can't use Opus if you don't have an Opus module installed.
|
||
|
|
2. The interface is stream-based, which should make developing with it more intuitive.
|

## Installation
|
||
|
|
|
||
|
|
You'll need to first install Node.js, and then you can install `prism-media` like so:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ npm install prism-media # latest stable release
|
||
|
|
$ npm install hydrabolt/prism-media # development
|
||
|
|
```
|
||
|
|
|
||
|
|
## Functionality
|
||
|
|
|
||
|
|
By default, no extra packages come with prism, so you're limited to just volume transformers and demuxers. This is so you can pick and choose which parts of prism you require.
|
||
|
|
|
||
|
|
| | Volume Transform | Demuxing | Opus | FFmpeg |
|
||

| [krypton](https://github.com/Hackzzila/krypton) | yes | | yes | |
|

|
|
| [node-opus](https://github.com/Rantanen/node-opus) | | | yes | |
|
||
|
|
| [opusscript](https://github.com/abalabahaha/opusscript) | | | yes | |
|
||
|
|
| FFmpeg ([directly](http://ffmpeg.org/) or via [ffmpeg-binaries](https://github.com/Hackzzila/node-ffmpeg-binaries)) | | | | yes |
|
||
|
|
|
||
|
|
### Opus
|
||
|
|
The 3 supported Opus libraries are `krypton`, `node-opus`, and `opusscript` (as shown above). They are also preferred by prism in this order; `krypton` is more performant, whereas `opusscript` is less so but doesn't require building upon installation.
|
||
|
|
|
||
|
|
### FFmpeg
|
||
|
|
If you would like to use FFmpeg with prism, you can either install directly from FFmpeg.org, or through ffmpeg-binaries (links in the table above).
|
||
|
|
|
||
|
|
If you're installing directly, you'll need to ensure `ffmpeg` is in your path, or that the executable file is placed in the root of your project's directory (with the package.json file)
