ums-mlx is a modified version of the Universal Media Server (UMS). mlx stands for Media Library eXtension. It has been started to allow more flexibility to configure what shows up on a renderer while keeping the powerful transcoding possibilities it offers.

Its functionality includes:

• Original Universal Media Server features
• Configure what files will show up in a folder by setting conditions (e.g. all action movies with kurt russell)
• Define how files will be sorted in a folder
• Flexible way to define the name of the file which will be shown on the renderer (e.g. '%name (%year) - %rating_percent/100 [%rating_voters]' will show 'The Dark Knight (2008) 89/100 [1480975]')
• Import video properties from imdb, tmdb and thetvdb (extensible through a plugin system)
• Show files either as single files or with more information in a folder (similar to the transcode folder included in UMS)
• Track the files you've played
• Reworked plugin system allowing full customization
