node-ffprobe's Introduction

FFProbe for NodeJS

A simple wrapper around ffprobe written in NodeJS

This module requires ffmpeg to be installed before it can function. The ffmpeg package comes bundled with ffprobe.

Installation

sudo apt-get install ffmpeg
npm install node-ffprobe

Usage

var probe = require('node-ffprobe');

var track = '/path/to/media/file.mp3';

probe(track, function(err, probeData) {
	console.log(probeData);
});

Calling probe will execute ffprobe and parse the data it sends to STDOUT. A sample object can be seen below.

The streams, format, and metadata fields are taken directly from ffprobe. probe_time is the total execution time for the given file.
