It looks like the Windows 10 UWP VLC app is finally going to make it to the Xbox One. According to one of the VLC developers the app has been submitted to the Windows Store for certification.
#VLC for #XboxOne has been submitted to the store, hopefully it will land in your living rooms in a few days!

All being well the app should be in the Windows Store in a few days. VLC plays a wide range of video formats, UNPnP/DLNA, network shares and picture in picture.
