.NEF files are Nikon's RAW file format (NEF = Nikon Electronic Format) and based on TIFF. Details on RAW files - https://en.wikipedia.org/wiki/Raw_image_format
Environment: Kodi 17.1 (Estuary Skin) running on Windows 10 x64 PC (Core i7, 16GB RAM). Picture Slideshow Screensaver Addon 4.2.1 from default repository.
So my assumption here is quite simply that FFmpeg used in Kodi (FFmpeg 3.1?) does not support .NEF file format. Does this look correct?
