Mediainfo

Mediainfo is a class wrapping the mediainfo CLI.

Installation

$ gem install mediainfo -s http://gemcutter.org

Usage

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

That will issue the system call to mediainfo and parse the output. You can specify an alternate path if necessary:

Mediainfo.path = "/opt/local/bin/mediainfo"

By default, REXML is used as the XML parser. If you'd like, you can configure Mediainfo to use Hpricot or Nokogiri instead using one of the following approaches:

  • define the MEDIAINFO_XML_PARSER environment variable to be the name of the parser as you'd pass to a :gem or :require call.

    e.g. export MEDIAINFO_XML_PARSER=nokogiri

  • assign to Mediainfo.xml_parser after you've loaded the gem, following the same naming conventions mentioned previously.

    e.g. Mediainfo.xml_parser = "hpricot"

Once you've got an instance setup, you can call numerous methods to get a variety of information about a file. Some attributes may be present for some files where others are not, but any supported attribute should at least return nil.

For a list of all possible attributes supported:

Mediainfo.supported_attributes

Requirements

This requires at least the following version of the Mediainfo CLI:

MediaInfo Command line,
MediaInfoLib - v0.7.25

Previous versions of this gem(<= 0.5.1) worked against v0.7.11, which did not generate XML output, and is no longer supported.
