mediainfo-simple

Description

This gem is a wrapper for the MediaInfo command-line interface.

How it works

It calls the MediaInfo command-line interface, and parses the XML output (obtained with mediainfo file.mp4 --Output=XML). Excepted for the MediaInfo CLI, it's 100% Ruby.

Installation

Dependencies

MediaInfo CLI. Installation:

• Mac OS X: brew install mediainfo
• Debian / Ubuntu: sudo apt-get install mediainfo

The gem

gem install mediainfo-simple

Usage

require 'mediainfo-simple'

info = MediaInfo.new "/path/to/file"

That will issue the system call to mediainfo and parse the output.

# check if there is a stream of some type
info.video?        # true
info.audio?        # true
info.image?        # false

# check the number of streams of some type
info.audio.count   # 2

# get metadata about a stream
info.audio[0].language  # "English"
info.audio[1].language  # "French"

See all the metadata attributes supported for each stream type in the corresponding classes in lib/mediainfo-simple/streams.

TODO

• add tests
• add methods to get duration in a particular format
