Ubuntu only NVENC, no NVDEC

Hi all,

So I bought myself a Geforce 1050 Ti and a lifetime subscription to enable HEVC hardware acceleration. I'm running Ubuntu 20.04 and installed the latest nvidia drivers(450.57) from the nvidia website.

Everything went well except  when I wanted to configure the advanced transcoding config it only showed up my graphics card to offload encoding. Decoding seems to be empty. See screenshot.

running ffmpeg encoders/decoders shows the following:

Can anyone point my towards the right direction to offload decoding as well?

 

Many thanks!

Yes, somehow it shows the decode options as well after a few reboots. No idea why exactly.

Thanks anyway :-)

What drivers do you have installed?
