Kodi can be used to play/view all common multimedia formats through its native clients and parsers. It can decode these audio and video formats in software or hardware, and optionally pass-through AC3/DTS audio, or encode to AC3 in real time from movies directly to S/PDIF digital output to an external audio-amplifier/receiver for decoding. Addons Manager, addons and plugins Kodi features several open APIs to enable third-party developers to create capabilities which extend Kodi with a multitude of addons, such as audio and video streaming plugins for online sources, screensavers, skins and themes, visualizations, weather forecasts, web interfaces, web scrapers, widget scripts, and more. Kodi developers encourage users to make and submit their own addons to expand media content and value-added services accessible from within Kodi. Kodi/XBMC features, since version 10.0 (codename: "Dharma"), an Addons Framework architecture and an Addons Manager GUI client that connects to a decentralized digital distribution service platform that serves add-on apps and plug-ins which among other things provide online content to Kodi, the "Addons Manager" (or "Addons Browser") inside Kodi allows users to browse and download new addons directly from Kodi's GUI. Many of these online content sources are in over-the-top content high definition services and use video streaming site as sources for the media content that is offered. Kodi has extensibility and integration with online sources for free and premium streaming content, and offers content from everything from commercial video to free educational programming, and media from individuals and small businesses. Not all content sources on add-ons are available in every country, however. Due to rights agreements, many content sources are geo-restricted to prevent users in outside countries from accessing content, although some have taken to bypassing the regional restrictions in order to unblock these sources, disregarding the usage rights. Plugins and scripts Kodi features an integrated Python Scripts interpreter for addon extensions, and WindowXML application framework (a XML-based widget toolkit engine for creating a GUI for apps and widgets) in a similar fashion to Apple macOS Dashboard Widgets and Microsoft Gadgets. Python widget scripts allow normal users to add new functionality to Kodi themselves, using Python scripting language. Current plugin scripts include functions like Internet-TV and movie-trailer browsers, cinemaguides, weather forecast, over-the-top content video streaming services like YouTube, BBC iPlayer, Hulu, Netflix, Veoh, MLB.tv, Internet-radio-station browsers such as Pandora Radio, online picture sharing sites like Flickr, TV guides such as TVShow Time, e-mail clients,
