Roku client crashes on certain files

[weird_hermiston]

Jellyfin version: 10.10.7
Installed on Raspberry Pi 4 via docker

n 10.10.7, I can't play some files on the Roku client. It's not all the files of these types, only some of them. 
I hit play, the playback progress gets stuck at 33% for a minute. Then the screen goes black and I get the following error:
"Error During Playback
There was an error retrieving the data for this item from the server."

Issues I see:

Code:

set_mempolicy: Operation not permitted

Do you have Jellyfin limited in some way via Docker? Or are you trying to run a RAM disk?

Code:

[2025-06-17 10:33:58.302 -05:00] [WRN] [98] Jellyfin.Api.Controllers.DynamicHlsController: cannot serve "/config/transcodes/9c1ae2838b2dec58f5bd364446b266590.ts" as it doesn't exist and no transcode is running

The expected next file is not present. It could have something to do with canceling playback, but likely a transcode problem.

There are other issues, such as the peak transcode speed on one of those files being 0.19x which would be unwatchable for hours before it finished. The main issue is that the Raspberry Pi is not powerful enough to transcode. Period. I used one back in the day and it's great if your media direct plays, but transcoding is a non-starter.
