Hardware Transcoding Linux/AMD GPU?

#1

Sorry if this was posted previously, I did a search for Hardware Transcoding but couldn't find a specific answer that is recent.

Does AMD based cards (ie Rx570) offer hardware transcoding in Linux? Currently I have a xeon based server that the CPUs don't offer hardware acceleration and I used a nVidia GT710 GPU to get access to hardware acceleration. I'd like to get a more powerful GPU for that machine and can get the rx570 at a semi-reasonable price, but if I give up hardware acceleration, I may not want to go that route.

Thanks,

Jay

Yes AMD transcoding is supported if you use a recent Ubuntu

Mint Linux 20.1 which I believe is based off of Ubuntu 20, so sounds like I should be ok. Thanks.

Installed am AMD RX 480 into my new test machine and installed channels DVR. Not seeing hardware transcoding option, just software. I installed the latest AMD graphics, any suggestion on how to diagnose and solve?

What are the permissions in /dev/dri? Does the user that the Channels process runs as belong to the group that owns the render nodes?
