Troubleshooting

Windows N / KN editions

• There are some editions of Windows (N and KN) that ship with greatly reduced built-in media playback capabilities.
• It seems like these editions don’t include MFPlat.DLL, but do include some basic DirectShow components. This means the Media Foundation playback path will not work.
• These editions of Windows require either a 3rd party codec installed (such as the LAV Filters for DirectShow), or the Microsoft Media Feature Pack:
  • Media Feature Pack for Windows 7 SP1 https://docs.microsoft.com/en-us/troubleshoot/windows-client/shell-experience/windows-media-feature-pack-for-windows-7
  • Media Feature Pack for Windows 8.1 https://www.microsoft.com/en-gb/download/details.aspx?id=40744
  • Media Feature Pack for Windows 10 https://www.microsoft.com/en-gb/download/details.aspx?id=48231
• We found that MJPEG DirectShow codec still works on these editions without installing the Media Feature Pack, so this the best choice for maximum compatibility
