No I don’t think so. Like I mentioned, I was able to reproduce on a machine I have access to. I created an internal issue for tracking. I will state that we don’t officially support transcoding with AMD GPUs at this time. So while it may have worked before there was never any guarantee that would c…

@skreii actually, yes, there is something. Could you share the XML info for Madea's Destination Wedding? I was able to reproduce your issue when attempting playback of a MPEG2Video file, I’m wonder if this codec is problematic for AMD specifically.

Server Version#: Any 1.43.x version Hello. Since the 1.43 server upgrade, the server will no longer use HW acceleration if I use any other client but the web one. I tried with the Android, Windows and LG apps and they are all the same. They show the same error and go back to software transcoding.…

Thanks for the fast answer. So what is the recommendation atm since AMD is not officially supported? Do I revert to 1.42 and wait until some day it works again or is there anything I can provide that can help troubleshooting this? I read the thread you linked and I can tell you that there isn’t a …

@skreii meet @m33ts4k0z . @m33ts4k0z I’ve moved your thread into this one, hope that’s ok. I had a question for both of you. When the issue manifests, do you have Tone Mapping enabled?

I have tried with both enabled and disabled and it still shows segfaults :grinning_face: PS: Latest version that it worked: 1.42.2.10156

Mine doesn’t work with it enabled or disabled. I built a custom plex container for 1.43.0.10492 and upgraded libva + libdrm as well as all of the dri drivers. It works now. [image] Build software better, together GitHub is where people build software. More than 150 million people use Gi…

What AMD GPU do both of you have? I have a RX 7600 in the test server I have access to. I was only ever able to see an issue when attempting MPEG2Video playback. Everything else seems to be playing fine for me. This is both on bare metal and docker.

From skreii’s logs I can see they have a AMD Ryzen 9 9955HX. So iGPU. Which could be why I’m not seeing this issue. Thanks!

Hardware transcoding works in Plex Web, but falls back to CPU in Plex apps (iOS / Android / tvos)
