Hey there, thanks for the reply. I have been tracking this down in several threads.
My plan is to pass one of my GPUs to ollama for voice assisistant duty and let the a380 do video encoding duty. I have not been able to get any of the docker applications to successfully use the gpus. Plex can see the gpus are present but does not use them for transcoding. The same has applied to all the other docker based apps such as immich and ollama.
Here are just a few of the other threads I have used to try to solve this problem:
- NVIDIA GPU Not Being Used By Apps - ElectricEel - #30 by Electr0
- Docker Apps and UUID issue with NVIDIA GPU after upgrade to 24.10 - #19 by Blake_Herbert
- Plex. " conversion failed. a required codec could not be found " - #17 by elrolo18
- Electric Eel Nvidia gpu passthrough support - #21 by rodneysing
Here is some more information about my setup if there is any additional detail you think would help please let me know!
