I don’t have freezing in FCPX, maybe because I am injecting the framebuffer Orinoco, 33W at idle.

I used iMac Pro 1,1 and iMac 19,1 with Sapphire RX 580 4GB and IGPU enabled.

Hello!
I can't get H264 hardware acceleration running. I tried already several approaches and at least got HEVC working though setting my MacModel. Can somebody help me get this to work?

My system is in the signature I believe. :)

What I have tried already:
(ref: https://www.tonymacx86.com/threads/...-h264-does-not-support-hevc-hw.240353/page-87)

1. Enable IGPU in BIOS, Inject->Intel=Yes, and use connector-less ig-platform-id=0x01620007. Or,
2. Change SMBIOS model type to iMacPro1,1. But you will get green glitches in the H.264 output. Or,
3. Keep your SMBIOS as-is and add boot flags: shikigva=32 and shiki-id=Mac-7BA5B2D9E42DDD94. Or,
4. Wait for MacOS 10.14.5 update

Do not inject intel or define an ig-platform-id. Just use WEG and lilu. I don't know if the RX570 will play nice with the iMac Pro 1,1 SMBIOS. Why dont you use iMac 14,2? Also remove the shikigva flag and radeondelnit. Do you make much use of HEVC?
I think the people changing to the iMac Pro SMBIOS are people with the Vega GPU
