"AAPL,slot-name" property breaks hardware HEVC encoder on Big Sur

Open bs3vcenk opened this issue 3 years ago • 7 comments

Describe the bug After trying (and failing) to encode several projects using the HEVC codec in Compressor and Final Cut Pro, I saw that the apps didn't even recognize the hardware HEVC encoder. Once I verified that VTEncoderInfo also fails to find the HW HEVC encoder, I found this post which said removing the "AAPL,slot-name" property in the config.plist fixes the issue. Sure enough, removing the key makes the encoder work again (the apps launch a lot faster too :).

This is the key in question: Bildschirmfoto 2020-12-04 um 20 37 58 Software Info macOS Version: 11.0.1 OpenCore version: 0.6.3 List of kexts:

After removing the above property still I am not getting `HEVC` support. Is it normal?

Does removing the shikigva boot arg fix it maybe? I removed it from my EFI as I didn't see any difference with it being there vs. without it (and the docs recommended against using it if it's not needed). If removing it doesn't break anything else, perhaps try that?

EDIT: Also adding my boot arguments:

boot-args	dart=0 darkwake=1 -cdfon

Hello, @btx3 I have removed the shikigva boot args but still the same issue. This is strange!

I have also a dual boot system, so I have checked in windows 10. It shows that the HW Encoding not supported. The discrete graphics is already turned off in the bios.

Please check the below screenshots:

Capture1 Capture3

Also could you please verify your processor using

sysctl -a | grep machdep.cpu

Here is the output of the above command:

Seems to be the same. I also checked your config against mine and found no difference! The only difference between our laptops seems to be that you have a dedicated GPU (mine only has the integrated Intel graphics). I'm thinking there's probably something trying to pass HEVC encoding onto the dedicated GPU, and then failing to do so.

Also, I don't have a Windows install to double-check, but I'll try to get one working during the next couple of days and report back.

Okay, thanks for the confirmation. @all-contributors please add @btx3 for testing and contribution.
