Server Version#: 1.41.5.9522 Player Version#: \ Hello all, I have a proxmox server set up with an lxc running plex. I have a nvidia 3060 that I want to use for HW acceleration. Plex is using the gpu for encoding, but not decoding. I have all of the nvidia drivers/cuda/nvidia-smi etc passed from the host. When I review the logs, it shows that it is using the gpu for encoding, but when I check nvidia-smi it shows no utilization which is strange. How can I get gpu decoding working? I have attached my logs, I just turned off verbose before starting a recent transcode [Plex Media Server Logs\_2025-03-20\_22-37-19.zip](https://forums.plex.tv/uploads/short-url/hxN4BjDQZa8p7quPyG4Jax6P1kq.zip) (1.1 MB) so these logs may potentially have some verbose entries so please accept my apoogies! ---

I’m not a proxmox expert or even regular user but have a working LXC which does HW transcoding. The container was setup using the TTECK helper scripts > **[GitHub - tteck/Proxmox: Proxmox VE Helper-Scripts](https://github.com/tteck/Proxmox)** > > Proxmox VE Helper-Scripts You should be able to tune it to your needs. ---

That’s actually what I started with, maybe I’ll try rebuilding the container from scratch with that ---

Here’s what it shows. Hopefully that helps ![Screenshot from 2025-03-21 00-47-39](https://global.discourse-cdn.com/plex/original/4X/9/b/c/9bcca72047ce7f0cc4f63bdbf1b9379e030bdc48.png) let me know what you need and how to get it. I’ll gladly share ---

it appears the bundled ffmpeg doesnt have support for HEVC sources to be used with nvidia hardware. Does that seem correct? I do have HEVC enabled in my setting on plex ---

Yes, the FFMPEG bundled with PMS does support HEVC sources and encoding. ![Screenshot from 2025-03-21 17-38-17](https://global.discourse-cdn.com/plex/original/4X/e/2/0/e203427580fa09daafe7d6b610f013809cacc7bf.jpeg) You MUST have hardware to support the HEVC encoding. There is no software HEVC encoder. I have a P2200 and RTX2000, HEVC has been supported for a long time (decoding) and HEVC encoding was recently added. In transcoder Advanced settings, did you explicitly select the Nvidia (by name) ? Are you passing the Nvidia runtimes into the LXC ? I add /dev/dri and then the runtime ```auto # Add it (Both Intel and Nvidia) lxc config device add "$1" GPUs gpu gid=$Gid # Add Nvidia runtime lxc config set "$1" nvidia.driver.capabilities all lxc config set "$1" nvidia.require.cuda true lxc config set "$1" nvidia.runtime true ``` ---

I can see the card from the lxc when I run nvidia-smi, and I think I have all the settings enabled in plex. Thats why I am leaning towards a plex issue rather than proxmox issue. ![image](https://global.discourse-cdn.com/plex/original/4X/4/d/5/4d5d24fb39ab0592e49876e65c67f225cfc18a4c.png) the logs indicate it is using nvenc for encoding but doesnt use nvdec for decoding ---
