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

You're welcome. The developer recently changed theat App to directly access the PerformanceStatistics of the active Accelerator.
If you want the app to show the other stats (CPU speeds, Fan, etc) then you have to replace your FakeSMC and sensors with those in that pack.

Same as justinhe: VirtualSMC and HWMonitorSMC2 and I can monitor my Radeon RX 560...
 
My bad, what was needed was "dummy141.kext", not "HEVC.10.14.1.kext".

Working fine now!!! Yesssss!

Thanks a bunch, I know that it wasn't a real showstopper to use old framework but I prefer this method.

Hi, would you mind sharing your clover folder and any kexts in L/E? I have a similar setup to you and just can't seem to crack getting HW accel working right.
 
Hello all,
i am all confused with this thread
i have these systems see signature
how do i get full hardware encoding/decoding support
if possible just using eGPU
Build # 1 Mojave 10.14.2
Build # 2 High Sierra 10.13.6 (latest one)
Build # 3 Mojave 10.14.2
please shed some lights
Thanks so much.

This thread for AMD RX4XX/5XX DGPU without IGPU system discussion, or people do not want to enable IGPU.

Enable IQSV is the easy way. if do not want to enable IQSV, better stay on latest High Sierra 10.13.6, native GVA support for RX580 and stable for HEVC encoding.

Pls notice that RX4XX/5XX H264 GVA decoder never work properly, other GVA functions OK.
From 10.14.1 up, RX470/480/570/580 GVA support no longer native (both H264/HEVC encode/decode).
 
Do these hardware encoding/decoding issues exist with Vega cards?

May not affect Vega cards, Vega GPU have better/native GVA support.

RX4XX/5XX freeze on FCPX export H264 issue, mostly found on SMBIOS iMacPro 1,1, due to hwe420 enabled in AppleGVA, change hwe420 setting to No from AppleGVA info.plist should fix this issue, change hwe setting to No will force H264 export work but in software mode.

FCPX H264 export mostly not freeze on other SMBIOSs, but failed to export.

Try change hwe and hweBGRA settings to No from AppleGVA info.plist, FCPX export H264 will work but in SW mode, QuickTime screen recording work in SW mode, other GVA functions still work.

@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

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
