Emby fails detecting GPU for HW decode & encode

[danergo 37]

Running on Ubuntu.

They usually updates drivers, so my Nvidia Quadro P400's DKMS must been rebuilt.

Now I have:

 

Although on server:

Nvidia drivers has been installed with:

sudo apt install nvidia-headless-550-server nvidia-dkms-550-server nvidia-utils-550-server

Note: this is a headless installation, I wish to avoid installing X.

I'm rather open to any suggestion. Nvidia seems working, but Emby just fails detecting it.

Hi, have you taken a look at our hardware acceleration setup guide?

Hi @Luke

Sure, and I know there is a section in this guide:

Always follow the instructions on the Nvidia site, even when the installed driver version appears to be sufficient!

On linked Nvidia driver's download page, there is also a section:

Note that many Linux distributions provide their own packages of the NVIDIA Linux Graphics Driver in the distribution's native package management format. This may interact better with the rest of your distribution's framework, and you may want to use this rather than NVIDIA's official package.

As I have a headless machine, I really wish to avoid installing a full display driver, just for transcoding capabilities.

In the meantime, I have found this awesome guy's post:

IMHO this should really be added to transcoding guides, for those few who uses NAS with Ubuntu without displays and don't want multiple unnecessary packages on their systems.

Slight addition to above guide:

1. Install NVidia's drivers (and kernel modules)

sudo apt install nvidia-headless-550-server nvidia-dkms-550-server

2. Install NVENC and NVDEC (for making it usable for Emby)

sudo apt install libnvidia-decode-550-server libnvidia-encode-550-server

3. Install utils (to be able to check the status with nvidia-smi)

sudo apt install nvidia-utils-550-server

 

For headless, "nvidia-settings" is unnecessary, but after those above packages have been installed Emby started recognizing the card:

@luke,

I can confirm operation with RTX 2000 ada and Nvidia 550 drivers.

Just purchased  RTX 2000 for use in NUC12DCMi9  due to form factor

All the pieces are installed and the GPU is seen/usable by other applications.

On $competitor, it shows as "unknown@nvidia" but does work for nvdec and nvdec + tonemapping

I'm available to help as needed.

You may want to give the 4.9 beta channel a try as it has updated drivers and an updated intel runtime.
