Mediainfo is a class wrapping the mediainfo CLI.
$ gem install mediainfo -s http://gemcutter.org
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:
MEDIAINFO_XML_PARSER environment variable to be the
name of the parser as you'd pass to a :gem or :require call.
assign to Mediainfo.xml_parser after you've loaded the gem, following the same naming conventions mentioned previously.
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
For a list of all possible attributes supported:
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.
