<FIXED>

use: advanced view extra parameters and enter: --device=/dev/ttyUSB0:/dev/ttyUSB0 to pass trough a device without privileged

It appears that the NVIDIA_VISIBLE_DEVICES environment variable is correctly set, as indicated by the first line of the output from the env command: root@8cd7369a97a4:/# env NVIDIA_VISIBLE_DEVICES=GPU-98c9b725-25ad-b43b-40c5-8fbceb5e0fc9 Additionally, I've noticed that Plex operates as expected when I explicitly specify the GPU device using the --gpus device=GPU-98c9b725-25ad-b43b-40c5-8fbceb5e0fc9 parameter. This leads me to believe there might be an issue related to how environmental variables are utilized compared to when GPU devices are manually specified. Is it possible that this discrepancy arises during a certain script execution at startup? It seems we might be looking for a command or script that improperly handles the "--gpus device=" parameter, potentially missing or misinterpreting the NVIDIA_VISIBLE_DEVICES environment variable. Could this be the case?

Yes i understand. --gpus device=GPU-98c9b725-25ad-b43b-40c5-8fbceb5e0fc9 does work but removing that line and just having Container Variable: NVIDIA_VISIBLE_DEVICES GPU-98c9b725-25ad-b43b-40c5-8fbceb5e0fc9 does not work, somehow NVIDIA_VISIBLE_DEVICES doesnt get passtroughed to the docker ?

the "--gpus all" makes the difference so i need to have that set with "Extra parameters"

yes i use Plex but i'am trying to troubleshoot the problem so i want to make sure it isnt a problem with Plex itself. i do not care about jellyfin its just troubleshooting. i got Jellyfin to work finally by using this guide: https://forum.jellyfin.org/t-gpu-transcoding-on-unraid now back to Plex.. drivers work, hardware work.. now focus on plex docker

Tried to downgrade the driver -> reboot -> doesnt work installed Jellyfin to make sure its not Plex itself but Jelly spits out this error: ffmpeg version 5.1.4-Jellyfin Copyright (c) 2000-2023 the FFmpeg developers built with gcc 11 (Ubuntu 11.4.0-1ubuntu1~22.04) configuration: --prefix=/usr/lib/jellyfin-ffmpeg --target-os=linux --extra-libs=-lfftw3f --extra-version=Jellyfin --disable-doc --disable-ffplay --disable-ptx-compression --disable-static --disable-libxcb --disable-sdl2 --disable-xlib --enable-lto --enable-gpl --enable-version3 --enable-shared --enable-gmp --enable-gnutls --enable-chromaprint --enable-libdrm --enable-libass --enable-libfreetype --enable-libfribidi --enable-libfontconfig --enable-libbluray --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libopenmpt --enable-libdav1d --enable-libsvtav1 --enable-libwebp --enable-libvpx --enable-libx264 --enable-libx265 --enable-libzvbi --enable-libzimg --enable-libfdk-aac --arch=amd64 --enable-libshaderc --enable-libplacebo --enable-vulkan --enable-opencl --enable-vaapi --enable-amf --enable-libmfx --enable-ffnvcodec --enable-cuda --enable-cuda-llvm --enable-cuvid --enable-nvdec --enable-nvenc libavutil 57. 28.100 / 57. 28.100 libavcodec 59. 37.100 / 59. 37.100 libavformat 59. 27.100 / 59. 27.100 libavdevice 59. 7.100 / 59. 7.100 libavfilter 8. 44.100 / 8. 44.100 libswscale 6. 7.100 / 6. 7.100 libswresample 4. 7.100 / 4. 7.100 libpostproc 56. 6.100 / 56. 6.100 [AVHWDeviceContext @ 0x565334ca3b00] Cannot load libcuda.so.1 [AVHWDeviceContext @ 0x565334ca3b00] Could not dynamically load CUDA Device creation failed: -1.

Hmm is there a way to downgrade driver version?

Yes, i saw you say that a few times in this thread so yes i made sure i used that. (with the OFFICAL banner in the corner) i also have plexpass Transcode happens.. but on cpu tried mobile phone with app and web based player forcing transcoding to 720p 1080P H264 stream smi-nvidia never shows anything happening.

Yes and Yes also made sure it isnt HDR but just 1080 for test.

Still nothing.. now the card doesnt even show up only "Auto"

I knew you where going to say that lol.. I started with the guide on page to that didn’t work and spend the whole day troubleshooting it myself (and added the other paths to forward the Nvidia device manually) the privilege mode was also a try I thought it might need root to access /dev/ but I will restore to the original template and report back (but 99,9% same result)

I’ve been attempting to set up hardware transcoding with Plex on my Unraid server, but I’m facing some issues. Despite ensuring that all drivers are installed correctly and verifying that the settings are configured as recommended, hardware transcoding refuses to activate. I’ve even tried running Plex through a different Docker container script, hoping it might resolve the issue, but unfortunately, I’m still stuck with software transcoding. To provide a bit more context, this is the first time I’m attempting to use hardware transcoding on my setup, and despite following various guides and ensuring my hardware should support it, I’ve not been successful in getting any program to utilize hardware acceleration. It feels like I’m missing a crucial step or setting, but I can’t pinpoint what it might be.
