Hardware acceleration (transcoding) not working

Plex Media Server

I’m running my Plex server on Docker with Ubuntu 20.04 as OS and I want to use my GTX 980Ti for the encoding. I installed the Nvidia driver version 460.73.01 and followed the Nvidia guide to get nvidia-docker2 to run. That all works (nvidia-smi works in a container and recognises the GPU) also turned on hw acceleration in the transcoder setting but Plex is still not using the GPU for anything did I oversee something? Don’t really know what it could be at this point. Also I installed the headless version of the Nvidia driver because I don’t want all the X11/Gnome stuff if that makes a difference.

Server Version#: 1.22.3.4392

Turns out it was the headless driver which plex doesn’t seem to use or recognise or smt similar. Just installing the normal driver without the recommended packages seem to work out well.

我遇到了和你差不多的问题，不过我们环境不一样，我的环境如下：
系统：win10
硬件：G5420，8G内存，插入了独立显卡GTX1650,安装了驱动程序（驱动程序版本: 27 .21.14.6231
）
问题描述：播放4K UHD的mkv格式视频的时候，关闭HDR（Enable HDR tone mapping）能正常调用GPU进行转码，播放正常，开启HDR（Enable HDR tone mapping）虽然显示转码，但是GPU并不工作，播放卡顿
