# ffmpeg-command
A simple ffmpeg and ffprobe child process handler, easy to add commands and execute
## Installation
In order to be able to use this module, make sure you have FFmpeg installed on your system (including all necessary encoding libraries like libmp3lame or libx264).
* [FFmpeg binary](https://www.ffmpeg.org/download.html)
```sh
npm i ffmpeg-command
```
## Usage
### ffmpeg
```js
import FFmpegCmd from 'ffmpeg-command';
const ffmpegCmd = new FFmpegCmd({ loglevel: 'info', cwd: './video' });
ffmpegCmd.add(`-i example.mp4 -af volumedetect -vn -sn -dn -f null /dev/null`);
console.log(ffmpegCmd.cmd());
//ffmpeg -threads 0 -hide_banner -y -loglevel info -i example.mp4 -af volumedetect -vn -sn -dn -f null /dev/null
ffmpegCmd.exec().then((stdout) => {
console.log(stdout);
