# ffmpeg-static

Static **[ffmpeg](https://ffmpeg.org) binaries for macOS, Linux, Windows.**

Supports macOS (64-bit and arm64), Linux (32 and 64-bit, armhf, arm64), Windows (32 and 64-bit). [The ffmpeg version currently used is `6.0`.](https://github.com/eugeneware/ffmpeg-static/releases/tag/b6.0)

[![npm version](https://img.shields.io/npm/v/ffmpeg-static.svg)](https://www.npmjs.com/package/ffmpeg-static)
![minimum Node.js version](https://img.shields.io/node/v/ffmpeg-static.svg)

*Note:* The version of `ffmpeg-static` follows [SemVer](http://semver.org). When releasing new versions, **we do *not* consider breaking changes in `ffmpeg` itself**, but only the JS interface (see below). For example, `ffmpeg-static@4.5.0` might download ffmpeg `5.0`. To prevent an `ffmpeg-static` upgrade downloading backwards-incompatible ffmpeg versions, [use a strict version range](https://docs.npmjs.com/files/package.json#dependencies) for it or use a [lockfile](https://docs.npmjs.com/files/package-lock.json).

Also check out [`node-ffmpeg-installer`](https://github.com/kribblo/node-ffmpeg-installer)!

## Installation

``` bash
$ npm install ffmpeg-static
```

*Note:* During installation, it will download the appropriate `ffmpeg` binary from the [`b6.0` GitHub release](https://github.com/eugeneware/ffmpeg-static/releases/tag/b6.0). Use and distribution of the binary releases of `ffmpeg` are covered by their respective license.

### Custom binaries url

By default, the `ffmpeg` binary will get downloaded from `https://github.com/eugeneware/ffmpeg-static/releases/download`. To customise this, e.g. when using a mirror, set the `FFMPEG_BINARIES_URL` environment variable.

```shell
export FFMPEG_BINARIES_URL=https://cdn.npmmirror.com/binaries/ffmpeg-static
npm install ffmpeg-static
```

### Electron & other cross-platform packaging tools

Because `ffmpeg-static` will download a binary specific to the OS/platform, you need to purge `node_modules` before (re-)packaging your app *for a different OS/platform* ([read more in #35](https://github.com/eugeneware/ffmpeg-static/issues/35#issuecomment-630225392)).

## Example Usage

Returns the path of a statically linked ffmpeg binary on the local filesystem.

``` js
const pathToFfmpeg = require('ffmpeg-static')
console.log(pathToFfmpeg)
// /Users/j/playground/node_modules/ffmpeg-static/ffmpeg
```

Check the [example script](example.js) for a more thorough example.
