Hey there, I’ve read a lot of comments stating that Plex HW transcoding can not be made to work with the vaapi APIs exported by AMD APUs with integrated graphics. This is true, at least looking at how Plex sets things up out of the box. Manually copying over the libva drivers for AMD GPUs plus rel…

@mauimauer Thanks for that. From what you supplied, it looks like it only supports the onboard GPU. Is this correct? If so, do you happen to know what it would take to support all capable Radeon GPU cards (of which there are many out there)? I ask because you did include radeonsi_drv May…

Sure happy to share a debug log. Just let me know where to drop it. I believe this should work with most recent AMD architectures that properly expose their capabilities trough vaapi (However I did not test with any other device, this Ryzen APU is my first team red system in a while). I have valid…

Check your PM The Ryzen is a real CPU again. :slight_smile: Ignore the marketing label LOL

This is fantastic! I have an 280X and Vega64. Will try to find some time to throw them in and test this during the week for h264 and h265 for 4k -> 1080p. I suspect the 280x hardware may not be able to do h265?

I am not sure about the 280x. The currently used core for recent APUs (Renoir in my case) seem to handle h265just fine and transcode 4K HEVC to h264 without a hitch. Some of the support will also be dependant to what version of libmesa/gallium/dri-radeon etc. your system uses. Hope someone can repr…

My system is Xen with passthrough to a Kubernetes host running in a domU (aka VM). I know Nvidia has a solid setup for this when running containers; however, I do expect to be venturing into some untested territory here. Hence the advantage to Xen: I can spin-up another domU running Ubuntu or some…

Awesome! Thanks a ton! Finally hw transcoding on my Renoir APU. I’m running Plex in a LXC container on a Proxmox system with GPU Passthrough. I had to switch my container to privileged and copy the files from /usr/lib/x68_64… to the destination folder. Have you tried HDR files? For me Plex is stil…

Yeah, that’s where the hope lies with the Plex Transcoder team, fancier features like HDR are likely to be buggy, this could be on the Plex or Mesa/Gallium side.

I suggest you try to play around with newer mesa/gallium/kernel versions. I am able to get HW transcoding for most HEVC 10bit files I’ve tested. Make sure to check your vainfo 5.10.4-051004-generic vainfo: VA-API version: 1.7 (libva 2.6.0) vainfo: Driver version: Mesa Gallium driver 21.1.0-devel …

Ah ok. My vainfo output looks the same (except I’m on a lower kernel). I was just curious if the problem was on my side. I’ve got only 4 files with HDR so right now it’s not important at all. All the other files are working fine and I’m super happy about it! Thanks again! Edit: HDR files work if y…
