b0mb 35 Posted October 26, 2022 Author Share Posted October 26, 2022 so here is the latest Logfile.... the problem is stil present.... sometimes all thumbs are extracted and sometimes only 3 of 25 maybe it would be worth a tray to force thumb extraction for a single movie but how to do? embyserver.txt Link to comment Share on other sites More sharing options...
b0mb 35 Posted October 28, 2022 Author Share Posted October 28, 2022 With latest Update the Problem is still present. Btw trying Plex doesn´t have any trouble with extracting.... ^^ Link to comment Share on other sites More sharing options...
Luke 37113 Posted November 2, 2022 Share Posted November 2, 2022 @softworkz will take a look at this. Thanks. 1 Link to comment Share on other sites More sharing options...

I´ve already opened a thread in another forum where are many users using unRAID and Emby.... I´ve also tried linuxserver.io Container and Jellyfin and all do have the same problem like emby which is appearing randomly.... Plex is working like a charm but as far as i´ve seen in the debug.log they don´t use ffmpeg for extracting the thumbs Link to comment Share on other sites More sharing options...
softworkz 3340 Posted November 3, 2022 Share Posted November 3, 2022 The point is: you're the only one reporting that issue. My suspicion is that it's related to I/O in some way, maybe related to seeking (random file access). The only way to circle down such issues is differential diagnosis, which involves and requires trying out things that are different and opposite to what you have right now. That's all I have to offer in the context of Emby. As it seems pretty clear that the issue is not related to Emby at all, you might want to perform some tests which involve accessing the same file in parallel from multiple sessions which also request different parts of that same file. The problem COULD be something like that the mounted storage fails to perform seeking and the mount client is forced to start receiving the file from start on each seek. Old SMB implementations were sometimes suffering from this alone or when in combination with parallel access requests, etc etc. Link to comment Share on other sites More sharing options...
Teddyknuddel 73 Posted November 3, 2022 Share Posted November 3, 2022 Also ich hatte ein ähnliches Problem - bei mir wurden die Thumbs aber erst gar nicht erstellt. Auslöser war, dass ich mit einem externen Editor, weiß den Namen leider nicht mehr, die Videobeschreibung, Bilder usw. bearbeitet hatte. Abhilfe war, dass ich alles im Videoverzeichnis bis auf das Video selbst gelöscht habe, und in ein neues Verzeichnis verschoben hatte. Dabei wurden die Kapitelbilder dann auch sauber neu eingelesen.

Nothing to lose - but nothing to win. You named what caused the problem in your case: 37 minutes ago, Teddyknuddel said: Auslöser war, dass ich mit einem externen Editor, weiß den Namen leider nicht mehr, die Videobeschreibung, Bilder usw. bearbeitet hatte. The OP didn't do that. You said: 40 minutes ago, Teddyknuddel said: bei mir wurden die Thumbs aber erst gar nicht erstellt which wasn't the case for the OP. I'm afraid, but I don't see any similarity. Link to comment Share on other sites More sharing options...
b0mb 35 Posted November 3, 2022 Author Share Posted November 3, 2022 @softworkz do you have any Explanation why this only happens to 4K Stuff? Link to comment Share on other sites More sharing options...

It's unlikely that it's really due to 4k resolution. Much more likely it's due to the fact that 4k videos are generally larger in size. Link to comment Share on other sites More sharing options...
softworkz 3340 Posted November 3, 2022 Share Posted November 3, 2022 ...other peripheral causes are possible: 4k videos are often HEVC and HEVC often has larger periods without key-frames, which means that it might cause more seeking or seeking over larger distances. Maybe, somewhere in the whole process, there's a parameter or value for which a threshold exists (maybe due to a bug or similar) and things go wrong once that threshold is exceeded. It's just a guess, though. Link to comment Share on other sites More sharing options...
b0mb 35 Posted November 3, 2022 Author Share Posted November 3, 2022 my complete metadata is outsourced to a share. Would it be worth a try to delete this metadata and rebuild the database? Link to comment Share on other sites More sharing options...
softworkz 3340 Posted November 3, 2022 Share Posted November 3, 2022 No. Such attempts are not effective at all. You need to make small and targeted changes and start form a completely different base. Forget about your existing library - create a new one where everything is different with just 1-3 videos and on a different storage. Link to comment Share on other sites More sharing options...
softworkz 3340 Posted November 3, 2022 Share Posted November 3, 2022 10 minutes ago, b0mb said: my complete metadata is outsourced to a share If you mean the main emby metadata folder, then configure your new library to store metadata inside the library - just as an example. Do everything differently for your new test library. The desired result is - of course - that the problem won't happen there. In that case, you would have a working case and a non-working case and you can assimilate the two subsequently until you find the culprit that makes the difference. But when the suspicion is already about file IO and you create the new library just on another unraid volume, you're dropping chances for achieving a "working case" situation Link to comment Share on other sites More sharing options...
