Any cMP with native AirPlay Mirroring?

With all the modern GPUs available one would think that we'd have plenty of power available for native AirPlay mirroring to be done.
I'm aware of AirParrot [2] however, it appears to no longer work for 10.13.4 and later. (I'm on 10.13.6)
By no longer work I mean instant kernel panic upon attempting to activate it to another display.

I've got an ATV4 that would be worthwhile to leverage along with an iPad Mini 2 (retina).

There are a few apps that allow one to leverage an iOS device as another display, however due to lack of AirPlay, the Duet app doesn't work, and the AirDisplay app also causes the Mac to kernel panic even though it doesn't use AirPlay (uses USB). And as you might imagine, the lack of actual AirPlay mirroring kills the ATV4. AirParrot had previously worked for this years ago.

I have a GTX 650 which has hardware 264 encoder, from what I understand the nMP also leverages the hardware encoder in the AMD card(s) it has. So one would think that the complete reliance on the Intel iGPU QuickSync is a scam, I've also seen reports that the Mountain Lion Dev preview 2 allowed for someone's old iMac to have native AirPlay Mirroring.

FWIW I am using the nVidia Web Drivers and have EFI flashed GTX650 so I have normal boot screens as if it was a real Mac card.

From the KP it is very clear that AirParrot is to blame.

All Nvidia GPU has no hardware encoding / decoding support in macOS.

All cMP has no GPU hardware encoding support in macOS yet (haven't test the latest 10.14 PB3 yet).

The only known hardware decoding working on cMP so far is the RX580 hardware decode in 10.14 beta.

That's pretty lame, you'd think that the WebDrivers would have been able to provide access to the hardware encoders in the GPU.

So I'm probably SOL then?

I thought I read somewhere that there was a requirement for the Mac's CPU to support SSE4.2 in order to run the newer AMD cards, which my 08 doesn't have (only up to SSE4.1)

Hmmm...

With my new RX 580 installed (Sapphire Pulse 8GB) I am newly getting the Airplay Mirroring icon in the menu bar. At first I thought it was a Mojave thing as that's where I first saw it, but then I booted back into HS 10.13.6 and it's showing up there too. It was definitely not there with any of my previous cards (stock GT120 and a MVC EVGA GeForce 750 Ti).

Thing is though, I don't know if it actually works since my cMP is at the office and my AppleTVs are at home. Hopefully someone else who has this same combo with available AppleTVs on the same network can verify. If not, then I'll try to bring one of my ATVs to work later this week.

For what it's worth, I've had the Airplay Mirroring Icon with a flashed 280X for quite a while, but it doesn't actually work.

H265 encoding will be needed, so we'll need to try again when the 580 supports it.

Would someone with an RX 580 and Mojave beta be able to try this and report back?

I should add, with my 280X in HS Airplay works from sources like Youtube, Quicktime, etc, but in Mojave Airplay doesn't work at all currently. Apple TV switches, but there's nothing but a black screen. My quicktime window switches, but then switches back.

I think it has to do with the switch to Airplay 2 and perhaps it's my Apple TV 3rd Generation.

Damn it was sounding so promising there for a bit. Just having the icon seems like perhaps it could be made to work.

Debated starting a new thread on this since things have changed a bit in the last 2 years mainly due to OpenCore.
But also figured, since I already had a thread about it, why not just bump it up from the grave?

So I decided to do a side-by-side comparison between my hack with a xeon and rx580 that does airplay perfectly with the iMacPro 1,1 smbios via clover and the cMP3,1 that is booting with opencore with AMD HWaccel enabled (RX 580 as well) and both into the same version of Mojave.

Now the 3,1 kind of thinks it is doing AirPlay, meaning the icon is in the menu and i can tell it to airplay to my ATV (or to another mac running 5kplayer that does airplay receiving for video / mirroring, which is handy to test with). When I tell the 3,1 to do AirPlay mirror the menu icon turns blue and in display prefs it lets me pick the AP Display but doesn't allow me to pick mirror mode or extended desktop.

This seems to put stress on the AirPlayXPCHelper process in Activity Monitor.
Using the "sample" function of Activity Monitor I can see there are some differences in what each mac is doing.

The "iMacPro1,1" hack has a few things that load that aren't loaded by the 3,1... the first being:
"/System/Library/Extensions/AMDRadeonVADriver2.bundle/Contents/MacOS/AMDRadeonVADriver2"
Which is getting heavily used by "com.apple.videotoolbox.compressionQueue" on the iMacPro, but, while "com.apple.videotoolbox" is loaded by both machines in the 'sample', there is no compressionQueue in use on the 3,1.
"/System/Library/PrivateFrameworks/AppleGVA.framework/Versions/A/AppleGVA" is also not loaded by the 3,1 but is loaded by iMacPro1,1 and is heavily mentioned in the videotoolbox thread as well.

Would seem to me that this would be the focus area on getting airplay to work ... getting AppleGVA to load properly which I'd think would then load the AMDRadeonVADriver2 automatically.

Thought I would bump this up to see if any movement has been made with Airplay and Mirroring on the cMP. It seems we are close. I searched around but the topic seems to get lost in the long OpenCore threads.

Why do you require native Airplay?
Try AirServer.
It works, but costs about 30$ for permanent license.
The same price for a Miracast, Chrome cast etc.... But with the casting dongles, you don't have to power on cMP.

Every non-native implementation I’ve played with has a ton of lag and doesn’t integrate properly.
