Plex Concurrent Transcoding only running one conversion at any one time despite available headroom

Featured Replies

I currently have plex set up to use my Quadro P600 to do some transcoding. However I noticed it's only doing one at a time

There is nothing in Plex settings that would hold it back

And the Unraid indicator to the GPU shows it can handle more

Not sure why it's only handling one transcode at any one time? Help?

Essential its told and forced to do one at a time...

 

your better off using a video convertor and transition the files into a mp4 / mkv file... for direct play use no transcoding...

- I paid for any video convertor for doing this years back with other tools and needs.

 

plex transcoding was more for live tv dvr tuner stuff and was more based on what tuner or session was open and available.
I have not see muti concuret optimizations work nor run on plex in a long time...

Well that's a bit disappointing :( Thanks for the links to the historical attempts to allow for concurrent transcoding
