Moonshine leverages the Windows Media capabilities from Silverlight, provided by the Moonlight browser plugin on Linux, and the Firefox web browser framework to enable the playback of legacy embedded Windows Media content on the web and local files on a user's desktop. It consists of two components: - Firefox/NPAPI plugin that handles legacy embedded Windows Media mime types. This plugin loads the Moonlight plugin and creates a XAML/JS player to play the media. This enables web sites like hbo.com and c-span.com to work on Linux. Additionally, the Windows Media Player ActiveX/JavaScript API is implemented to enable the most compatibility. - Chromeless Firefox overlay for playing back local WM content from a user's desktop. A .desktop file and launcher is provided for easy integration with Linux distributions.
