node-ffmpeg-installer

Platform independent binary installer of FFmpeg for node projects. Useful for tools that should "just work" on multiple environments.

Installs a binary of

ffmpeg
for the current platform and provides a path and version. Supports Linux, Windows and Mac OS/X.

A combination of package.json fields

optionalDependencies
,
cpu
, and
os
let's the installer only download the binary for the current platform. See also "Warnings during install", below.

Install

npm install --save @ffmpeg-installer/ffmpeg

Usage examples

const ffmpeg = require('@ffmpeg-installer/ffmpeg');
console.log(ffmpeg.path, ffmpeg.version);

process.spawn()

const ffmpegPath = require('@ffmpeg-installer/ffmpeg').path;
const spawn = require('child_process').spawn;
const ffmpeg = spawn(ffmpegPath, args);
ffmpeg.on('exit', onExit);

fluent-ffmpeg

const ffmpegPath = require('@ffmpeg-installer/ffmpeg').path;
const ffmpeg = require('fluent-ffmpeg');
ffmpeg.setFfmpegPath(ffmpegPath);

Known issues

Warnings during install

To automatically choose the binary to install, optionalDependencies are used. This currently outputs warnings in the console, an issue that is tracked by the npm team here.

AWS and/or Elastic Beanstalk

If you get permissions issues, try adding a .npmrc file with the following:

unsafe-perm=true

See issue #21

Wrong path under Electron with Asar enabled

It's a known issue that Asar breaks native paths. As a workaround, if you use Asar, you can do something like this:

const ffmpegPath = require('@ffmpeg-installer/ffmpeg').path.replace('app.asar', 'app.asar.unpacked');
