Can anyone smoothly play HLS-HEVC 4K videos under linux in a NUC 5i7? If so, which player are you using?
Intel does not test and validate Intel® NUC on Linux; however, I know that a lot of NUC owners are using it successfully on many different Linux distros.
Intel suggests you check your Linux distro's website and forums for peer assistance with this issue.
