Hi

Running TrueNAS-SCALE-22.02.3 and offical Plex App Plex 1.28.2.6151_1.7.20

It seems that since upgrading one or both of these in the last weeks may have resulted in transcoding errors.

I have tried deleting the codec folder contents as I found in other forums but that has not helped. Not sure if it's a permissions issue but I hadn't changed anything before it stopped working.

Here are some of the errors in the Plex console:

There are no errors in the console I can see until I try and play something that needs decoding.

I thought it might be the GPU so changed it from a 1050ti to a 1070 but it has ended up making no difference. I do have access to nvidia-smi in the truenas shell. Rolling back plex one (which ithe only option I have) does not fix it. I also rolled back one version last week when this started of Scale but that also did not fix it. I also deleted the app completely (all the settings were stored in specific locations) and reinstalled it with still no luck.

Can anyone provide and help or tips. I did a debug but not sure if It's ok to attach it here. If you need any further info pleae let me know.

Thanks

After further investigating it looks like it might have been a coincidence in timing with the updates. The plex library must have increases in size to the point it caused issues due to a large number of file and surpassing the inotify limit

I have added a fs.inotify.max_user_watches in cysctl and it appears to be all good now.
