I'm a retired IT guy, but completely new to media servers. Hoping someone can help me understand what I'm seeing.
Jellyfin for Docker 10.10.7
Synology DS1522+, DSM 7.2.2-72806 Update 3
CPU usage runs extremely high (80-90%) on certain titles. My libraries include around 70 movies - most Blu-Ray, some DVD - and a handful of TV shows. Of the TV shows two are Blu-Ray, the others from DVD. About a dozen of the movies and one of the TV shows run high CPU, the rest use negligible CPU (1-2%j). All were ripped from disc to MKV. I haven't found much common among those that exhibit the problem, other than they're all Blu-Ray and I don't seem to observe the problem with those ripped from newly-purchased discs. The only other thing that comes to mind is possibly release date; for example, I see the issue with Band of Brothers (2001) but do not with The Pacific (2010). I would have to analyze a bit more to determine if there is any real correlation there.
The difference is stark between titles with the issue and those without; I would post screenshots of resource monitor from DSM but I can't seem to upload anything here, having tried to upload a log already (I'll try another browser later). One will show CPU over 90% and RAM usage 15-20%, the next will show CPU near 0 and RAM 4-5%.
Any information / suggestions will be most welcome.
Thanks,
Mark
