Hello Guys.
I have some short videos, which are downloaded from the net. I put them to a library. All videos had thumbnails, so a preview picture was shown for each video. This was ok for a few month and after that, suddenly these thumbnails gone for good.
I deleted the plex and installed it again, the settings stayed the same, but this thumbnails (preview pics) do not want to appear.
Is there anybody, who can tell me, what to do, what to set?
Thank you.
