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

[claybitner]

After enabling dummy14.kext, the Airplay mirroring showed up and hardware acceleration also looked like it should be working in VideoProc, however when I would try to export anything in FCPX, I would get "error -12912". As soon as I took out dummy14.kext, FCPX would render again, but no more Airplay or hardware acceleration in VideoProc.

I'm also using the bootflags

shikigva=32
shiki-id=Mac-031B6874CF7F642A

I had the same issue. Do you have Inject ATI/Intel? You use the IGPU or only the GPU?

ig-platform-id=0x01620007 this for my CPU. So you muss set the headless IGPU Value from your CPU.

That's normal.

Your options are:
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

I use Option 1 at the moment with my i7-3770K until Option 4 is available.

You have not stated what SMBIOS model you are currently using.

I'm attempting to be able to use both iGPU (HD530) and GPU (RX580). My Display port goes from the RX580 to my monitor. I don't have Inject ATI or Inject Intel turned on, but I do have Whatevergreen.kext and Lilu.kext in my /EFI/CLOVER/kexts/Other folder.

You must set Inject Intel and the Platform-ID from the Intel in Clover. This was also my Fault.

Here you can find your Headless Platform-ID

Just tried it and I'm still getting "error -12912" exporting in Final Cut Pro X. (If I have dummy141.kext)

You removed shikigva=32, shiki-id=Mac-7BA5B2D9E42DDD94?

Tried with and without shikigva and shiki-id. Same result.

Funny thing is that even with Inject Intel turned on, VideoProc sees the HD530, but the System Profiler doesn't.

You tried to delete your dummy kext? Maybe you didnt Need this kext. While your IGPU is newer and can handle the Codecs
