Mediainfo

Wrapper around the mediainfo command for obtaining information about media enhanced with the Q promise library 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", [...]).then(...)

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