I have a bunch of MKV files generated by Handbrake that LibreELEC can play, save for a single one of them. Nothing happens when you try to play the file in Kodi, but in the log file you can see
ERROR: CVideoPlayer::OpenInputStream - error opening [smb://nasname/pathtofile/video15.mkv]
The problematic file plays without problems in VLC and in Windows 10's native Movie app. I use a Raspberry Pi 3 with LibreELEC 9.1.002 running Kodi 18.3.
Does anybody have any ideas on what to do?
