Intel QuickSync not working

[osy]

In /System/Library/PrivateFrameworks/AppleGVA.framework/Resources/Info.plist, under System Support, the entry for Mac-7BA5B2DFE22DDD8C does not contain forceOfflineRenderer. On a real Macmini8,1 there is no dGPU, so this is fine but we need offline rendering.

Changing the model to iMac18,2 or iMac18,3 works but causes another issue: the USB-C in DP mode no longer output video.

Another solution is to use WhateverGreen's Shiki with boot-arg shikigva=32 shiki-id=Mac-BE088AF8C5EB4FA2. This works but currently, WG is incompatible with Polaris22Fixup until osy/Polaris22Fixup#3 is resolved. Additionally, WG has a whitelist system so QuickSync will only work with the apps that are whitelisted, which is not a good solution imo.

We have to either resolve the USB-C DP issues with board-id Mac-BE088AF8C5EB4FA2 or somehow fake the forceOfflineRenderer check in AppleGVA without WG.

So this is the reason why my Ultrafine 5K does not work.

@dongyj1987 Which part? The quicksync or the iMac18,2 spoofing? You can try the WG workaround I talked about, but you have to remove Polaris22fixup.kext first. This will cause the graphics issue to show up but you can confirm if quicksync is the issue.

The quicksync, cause it's Mac mini spoofing now. I will try WG while removing Polaris22fixup like you said and see what will happen. Thanks a lot!

I can confirm changing smbios to iMac18,3 activating QuickSync (without WG), tested with Safari (youtube) QuickTime Recording, Kodi, VideoProc, basically at the moment for Macmini8,1 there is no any GPU acceleration for Enc/dec. Im just wonder why nothing work through AMD GPU ?

Good for testing use Intel Power Gadget tool, at least for Intel GPU - showing if something going through GPU, iStats will no show any load. also Kodi showing Procesing info if we press O during playback.

update: only chrome still not using HW acceleration :( over Intel or AMD. I tried force him in settings
"about:flags" but still 4k running SW (I know chrome using VP9 mostly but still should work)

Apple's drivers does not support video encoding/other features on many AMD chipsets including Baffin (which we're spoofing). I think they've added some support in 10.15 but I doubt it applies to older chipsets.

[piotrasd]

It has - apple using Video Toolbox which suppose to work even Buffin at least for H.264 and HEVC
https://developer.apple.com/documentation/videotoolbox
Anyway I will deep more, check what the story, people with RX460 (Polaris Buffin family)and others they got full acceleration. For me target is FXCP.

And solve mistery of VP9

[osy]

If so then it's probably some config in AppleGVA. Play around with the WG shiki settings I guess.

dos change PEGP to GFX0 , change HECI to IMEI patch and dAGPM.kext necessary to active quicksync?

[osy]

They are not necessary.

[piotrasd]

@slimx just enough change SMBIOS to Mac18,3 and you will get. Today I got info to get HW dec/enc HEVC with AMD best to change on iMacPro1,1

"Only SMBIOS iMacPro1,1 support AMD GVA H264/HEVC encoder, no other options on latest macOS."
(but we suppose turn off intelGPU or change AMD on GFX0, today I will more test and confirm)
for some reason they removed for others options after 10.14.4

@osy86 maybe config of iMacPro1,1 will work with USB-C/DP etc ?

[piotrasd]

with SMBIOS iMac19,2 im getting both HW acceleration, not everywhere. but safari, iTunes using QSV and FCP AMD ... so for me perfect.

BruceX Test - 5K.fcpxml.zip I attached testing project file for FCP where you can easily check load of GPU during rendering and you can compare time.

[osy]

Closing as the original Intel QuickSync issue was resolved. Please open a new issue to discuss AMD HW acceleration issues.

[piotrasd]

Release 2.0 didn't work at least for Chrome and safari, clean install with WG (default config nothing changed)

hi there,

Quick questions here Quicktime player to encode videos. seems like it's not using quick sync ?
i trying to use handbrake to encode with quick sync, it crash.

This also including video decoding on h264, on quick time player is that known limitation of this build ?

i am using latest clean new install
OS: 10.15.6
HacMini: v2.10

update: chrome watch h264 is not using quick sync too

chrome://gpu results

Update: 26 Jul 2020

I decided mount EFI folder, and delete all, and reinstall latest hacmini v2.10. it seems resolve the issues.

i did the same upgrade/re-install couple time no effect, delete the original EFI folder on boot drive and reinstall did the trick for me

here is my option

thanks @osy86 for the great work :)
