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

[itwas]

Hi Everyone, a bit late to the party here, but I am using release version of macOS 10.14.4 with iMacPro1,1 SMBIOS and RX 580 8GB, and have hardware encoding working with dummy141.kext only (and PEGP to GFX0 in Clover).

./VDADecoderCheckerSierra

Hardware acceleration is fully supported

also, MacX Video Converter Pro shows RX 580 with Hardware Encoding = Yes

I don't know what I am doing wrong, but playback with MPV of test HEVC file is still decoding in software???

Is there a better method of testing or better software to test playback is hardware accelerated??

Many thanks for any help in advance

try this mpv parameter
mpv --hwdec=auto /path/to/your/hevc/video/file
or
mpv --hwdec=videotoolbox /path/to/your/hevc/video/file

can you playback h.264 video with hardware acceleration
what mpv version did you use for testing

Tried both auto and videotoolbox, HEVC still software decoded

Tried three H.264 videos, only two decoded with hardware:

Using hardware decoding (videotoolbox).

(NOTE: the first video may not have been H.264!!)

Which SMBIOS profile are you using? Do you have iGPU enabled?

Could you please post the dummy141 file? I'm having a hard time looking for it in this thread.

SMBIOS MacPro6,1 does not support hwe420, share as H264 will not work, add WEG boot flags to tell OS use iMacPro1,1 GVA properties

I have entered these two args in the config file and added dummy file to Other folder. I disabled IGPU in BIOS. Is there anything else I need to do?

Also, Netflix is no longer working. Does it work for anyone else with the latest Mojave build?

I have Netflix working with SMBIOS iMAC14.1, IGPU enabled in Bios, Dummy.kext installed and configured the IGPU with a headless Framebuffer in Clover.
