You need to get these packages to use FFmpeg.
yarn add fluent-ffmpeg @ffmpeg-installer/ffmpeg @ffprobe-installer/ffprobe
fluent-ffmpeg— wrapper for ffmpeg command@ffmpeg-installer/ffmpeg— ffmpeg binary@ffprobe-installer/ffprobe— ffprobe binary
Example ffmpeg.js file. No more settings need. Require it and use.
const ffmpeg = require('fluent-ffmpeg')
const ffmpegPath = require('@ffmpeg-installer/ffmpeg').path;
const ffprobePath = require('@ffprobe-installer/ffprobe').path;
ffmpeg.setFfmpegPath(ffmpegPath);
ffmpeg.setFfprobePath(ffprobePath);
module.exports = ffmpeg;
Usage
Now you can use FFmpeg API.
const ffmpeg = require('./ffmpeg');
ffmpeg()
.input('voice-message.ogg')
.save('voice-message.wav');
Electron app
If you want to package binaries to Electron app compressed with asar, update path strings.
const ffmpeg = require('fluent-ffmpeg')
const ffmpegPath = require('@ffmpeg-installer/ffmpeg').path;
const ffprobePath = require('@ffprobe-installer/ffprobe').path;
ffmpeg.setFfmpegPath(ffmpegPath.replace('app.asar', 'app.asar.unpacked'));
ffmpeg.setFfprobePath(ffprobePath.replace('app.asar', 'app.asar.unpacked'));
module.exports = ffmpeg;
For bundled app paths to binaries will be updated. While app is in development mode (not bundled) FFmpeg will be requested from node_modules directory directly so replace function will do nothing.
