Transcoder Hanging/Crashing on 4k -> 1080p

Bennnnnnn · August 29, 2023, 4:11am

Server Version#: 1.32.5.7349
Player Version#: Plex Web 4.108.0 & Plex for Windows 1.76.2.3951-15712eae

Setup: Proxmox VE → Ubuntu docker → LinuxServer Plex image
GPU: Nvidia A2000 12GB
Drivers: 535

I’m having transcoding issues on a new Plex server build.
Basically, it’s extremely hit-or-miss on whether a 4k file will transcode or not. It seems like 4k → 1080p is the most broken, while 4k → 720p or lower works fine.
Also, it seems to take an extremely long time for streaming sessions to start (sometimes >2 min).

Things that work reliably:

Direct play
4k → 720p transcoding
1080p → any transcoding
Starting streams on Plex for Windows

Things that work sometimes:

Starting 4k streams on Web
- Sometimes it starts and direct plays
- Sometimes it starts and transcodes to 720p successfully
- Sometimes it fails to start

Things that reliably fail:

4k → 1080p transcoding
Changing quality multiple times in the same session
- On Web: the spinning wheel goes forever
- On Plex for Windows: the session crashes/quits

I have tried deleting the “Codecs” folder, and it seems to help for the first session afterwards, but then the behavior resumes. I am seeing mostly similar issues with both the Web player and the Plex for Windows application.

Are your problematic 4k files HDR or SDR? If you are trying to do HDR to SDR then you are doing tone mapping in addition to a resolution change, so more is going on.

Bennnnnnn · August 29, 2023, 11:32am

Okay yes, the problematic files are HDR.
I have HDR tone mapping enabled.

Hopefully this is useful information.
