Ubuntu only NVENC, no NVDEC

[groes 0]

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!

Hi there, have you followed our hardware acceleration setup guide?

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?
