@shuhung Thank you for your help
so if i get the Vega Card then i will get the full Hardware Encode/Decode support on Mojave 10.14.2?
and how do i enable GVA Support?
also is it possible to get full Hardware Encode/Decode support if i enable the iGPU?
I bought the Sapphire VEGA 56, just removed the RX580 and put the VEGA.

I left the IGPU enable for h264 and was immediately given HEVC by hardware. :)

SMBIOS 14,2, WEG + Lilu

regards

do you mind if i ask you where did you get your vega 56 from?

also, you had nothing else modify in clover -> config.plist?
do you mind sharing your clover -> config.plist?

The proof is in actually doing an encode.
Open a short 4K HEVC file in Quicktime.
File -> Export...
Check the HEVC box to export it as HEVC 1080P.

while it is doing the encode, watch the CPU + IGPU utilisation in Intel Power gadget and AMD utilisation in Activity Monitor -> Windows->GPU history

on compressor, encode to HEVC.

Looks good.
Intel power gadget and Activity monitor GPU monitor are more accurate.

What about H.264 encode ?

For Vega GPU export H264 or screen recording, may need hwe420 enabled in AppleGVA info.plist, SMBIOS iMac14,2 does not have hwe420 support.

Recently, hwe420 does not work with RX4XX/5XX, will cause system freeze when screen recoding or export H264.

Looks like bad news with 10.14.3 Beta.

The H/W accelerators are still left out.
Looks like dummy kext will still be required to re-enable them ...probably with all the instabilities/inconsistencies in behaviour.

Yes, on 10.14.3 beta2, still no native GVA support for RX4XX/RX5XX.

When dummy141.kext is applied, for system stability, need edit AppleGVA info.plist, remove below setting if exist, screen recording and export H264 will work (CPU + GPU metal).
