Installation

First make sure you have the ffmpeg binary downloaded and globally accessible on your machine.

const args = [
    '-i', './video.mov',
    './video.mp4'

With parsed progress:

import { run, parse } from 'ff-util';

const args = [
    '-i', './video.mov',
    './video.mp4'
]

const logger = (stdOut: string) => {
    const parsed = parse({ffProgressLine: stdOut})
    console.log({parsed})
}

run({args, logger})
    .then(() => console.log('process complete!'))
