Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

I updated to 10.14.6 Beta and H264 stopped, in 10.14.5 everything worked fine, did anyone have the same problem?

AMD GVA H264/HEVC acceleration work correctly on latest 10.14.6 beta.

do you need some extra kexts or configuration?
I send my EFI folder if anyone can help ..

No, just use SMBIOS iMacPro1,1.

Does anyone actually have their AMD GPU hardware doing the encoding???
Ive tried imac pro smbios as well.

Turned off IGPU in bios with imacPro smbios.
I guess its just a bug in the software since gpu history window shows Vega doing the work.
Can anyone confirm???

Yes, I think it's a cosmetic error.

Edit:
I did a little more testing. I think VideoProc uses different hardware depending on what you ask the app to do. For example, I tried to rotate a video and add the greyscale filter before converting to HEVC and only the CPU was used.

When I did an HEVC to H.264 conversion without any filters, it used GPU and CPU.

Thanks for checking

Hey Shuhung, do you think this update will solve the DumpGPURestart freezes on the RX580?

Just bought a RX580 to upgrade my Haswell (4770k on 14,2) rig to Mojave and am getting the annoying freezes. Was looking at changing SMbios to iPad Pro and use the dummy kext etc but if the new version of Mojave fixes it, I'll download the beta and install.

If you have any ideas on how to solve the freezes (I don't do any video work so HEVC is secondary) that would be great. Thanks.
