Mediainfo

Wrapper around the mediainfo command for obtaining information about media files.

Overview

This module provides an interface to the mediainfo command. It returns the (parsed) output of the command with all the keys lower-cased. There's not a lot to say here.

Usage

The module exposes just one function, which has a signature of:

mediainfo("/path/to/file", "/path/to/other/file", [...], callback)

The callback function is called, in familiar node fashion, with two arguments. The first is an Error object on error, or null on success. The second argument is an array of objects, forming what you'd expect from the output of mediainfo, if it were mangled into a JSON object.

It's really easier to just see the output, so here:

(bite me, it's a decent track)

Example

var mediainfo = require("mediainfo");

mediainfo("/path/to/something.mp3", function(err, res) {
  if (err) {
    return console.log(err);
  }

  console.log(res);
});

Requirements

The mediainfo command has to be available somewhere in the PATH of the user node is running as.
