I am attempting to generate video preview thumbnails for a movie library. I understand that “video preview thumbnails can take a considerable amount of time and CPU resources. It’s not uncommon for a single movie to take 10 minutes or more of processing, during which the majority of your CPU resour…

I wanted to close this thread out for anyone searching or for search engine indexing… The solution (as of May 2022) is to use a third-party python script to generate video preview thumbnails. Github is https://github.com/stevezau/plex_generate_vid_previews . Advantages over just letting Plex handl…

Take a look at the results of the top command. You’ll be able to tell that way if Plex is only maxing out a single core for a process. My system takes a few minutes to generate preview thumbnails as well, it’s normal and I wouldn’t consider it to be problematic. Depending on the amount of media tha…

Top would indicate its a single threaded process as it hovers around 100%. It is unfortunate that, like much in Plex, there is no configuration or tuning options available to speed up or slow down generation. I don’t need the resources saved for anything else, they are readily available. Also, I …

I hear you, I’ve got plenty of resources as well. It is what it is though, everything functions as it should - just maybe not as quickly as it could.

While you might have cores and memory to spare, things like NAS boxes don’t. Trying to write a dynamic-loading control module which could load the CPU with administrative tasks then adapt instantaneously to on-demand user-playback / transcoding would be extremely difficult. Such a piece of cod…

Understand and agreed. Adaptive, dynamic scaling would be amazing but highly complex. However, a single dropdown option which allows the selection of X number of concurrent tasks is substantially less tedious to code and would yield enormous gains for those of us who aren’t using an ARM processor …

I just found this from @stevezau and I am going to give it a try. Looks amazing. I will work on a feature request in a bit as well.
