Previous versions of this gem(<= 0.5.1) worked against v0.7.11, which did not generate XML output, and is no longer supported. This requires at least the following version of the Mediainfo CLI: MediaInfo Command line, Some attributes may be present for some files where others are not, but any supported attribute should at least return ‘nil`.įor a list of all possible attributes supported: Mediainfo. Once you’ve got an instance setup, you can call numerous methods to get a variety of information about a file. * assign to Mediainfo.xml_parser after you've loaded the gem,įollowing the same naming conventions mentioned previously. Name of the parser as you'd pass to a :gem or :require call.Į.g. 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 Moving on, REXML is used as the XML parser by default. It contains a bunch of relevant usage examples. duration # raises SingleStreamAPIError !įor some more usage examples, please see the very reasonable test suite accompanying the source code for this library. Quicktime files can often contain artifacts like this from somebody editing a more ‘normal’ file. Sometimes you’ll have more than one stream of a given type. The first approach assumes one stream of a given type, a common scenario in many video files, for example. When inspecting specific types of streams, you have a couple general API options. Once you have an info object, you can start inspecting streams and general metadata. You can specify an alternate path if necessary: Mediainfo. That will issue the system call to ‘mediainfo` and parse the output. However, there is one parameter available, described in the following table.Mediainfo is a class wrapping ( ). Typically, Windows calls wmpnscfg with no command line parameters. If the user clicks the popup, wmpnscfg launches Windows Media Player, which displays a dialog box that asks the user to either allow or deny sharing with the new device. When wmpnscfg is notified that a new media device is available on the network, it displays a popup in the system tray that informs the user about the availability of the new device. Wmpnscfg starts the Windows Media Player Network Sharing Service (NSS) and then waits for notifications from the service. Microsoft Windows uses wmpnscfg.exe to alert users when media rendering devices are found on the network.

Windows Media Player supports a set of command line parameters that specify how the Player behaves when it starts. In this article Command Line Parameters for Wmplayer
