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

Both AMD HEVC/H264 GVA encoder work and fast, for HEVC encoding, recently only support 8 bit.

Forget to attach result, HEVC transcoding FCPX to Compressor

Sorry it was my fault, i did rename PEGP to GFX2 in clover, removed that line, now my GPU is GFX0. everything works. Great thanks for your help.

Looks like Apple finally figured out how to take advantage of AMD GPU multimedia encoding and decoding features.

This version work not equal to next version will also work, backup this version first, due to AMD GVA support still not official for RX4XX/5XX.

thanks, already saved /System/Library/PrivateFrameworks/AppleGVA.framework to Dropbox

No, I don't enable IQSV, for HEVC transcoding RX460/RX570 are much better, no reason to enable IGPU for me.

So, what's the current solution (with 10.14.3) to enable HEVC AND H.264 encode in FCPX ?
Specific model ID, framework hack ?, dummy kext ? WEG ?

After 647 post, I seem to have lost track

You need 10.14.4 for stable encode and decode of RX 5xx/4xx GPU. see post #635 #637.

Mojave 10.14.3 not work, only for 10.14.4 (18E174f), still need dummy141 kext to enable AMD GVA support, SMBIOS with hwe420 support (recently only iMacPro1,1 support hwe420), with or without WEG no relevant .

Someone with Xeon and RX580 have smbios iMacPro1.1? Could share EFI folder?

You could use a iMacPro1,1 SMBIOS OR a better way you could keep your current SMBIOS but just use “shikigva=32 shiki-id=iMacPro1,1’s board-id” boot args to tell AppleGVA that your mac is a iMacPro1,1. See post #635. I have E3-1230 v2, RX560 and i use Macpro6,1 with above boot args.
