Hendrik how is your external power supply set up? I spent a day trying to get my radeon working then realised The trouble I had was related to one dead Radeon VII after all. It takes about 7min to boot.
Got a tip for us?

MP 1,1-5,1 Activate AMD hardware acceleration

Thanks for the info. I never own any newer Mac, no idea that the AMD driver that doesn't allow eGPU to do HEVC hardware accel.
No video, all steps are very simple and listed in post #1.
For HEVC, this mod only allow hw decode in macOS at this moment, haven't figure out how to get encoding yet.
Yes.
But with this board-id injection method, we can only get HEVC hardware decode, but not encode.
This mod only make the AppleGVA framework believe our Mac has the iMac Pro board-id. The OS itself still read our cMP as cMP. May be this cause the difference.
Yes, the project and the library are in PCIe SSD.
You tell me where to check the storage throughput data exactly.
Thank you.
Can confirm - using WhateverGreen 1.2.9 on an RX 580 I saw no acceleration. Using 1.2.8 I do.
when the clip has been rendered the reading is: data read between 30-65 MB
before being rendered it is between 10-15 MB with peaks at 18MB sometimes.
So I swapped from nvidia quadro M2000 to RX 580 8Gb Red Devil PowerColor to be able to upgrade to Mojave and take advantage of hardware [de|en]coding.
Some of this info may or may not be useful as it is not in a real mac pro.
using the iMacPro 1,1 definition the video proc test for h264/hevc decoding in 10.13.6 seems to cause the GPU to crash and the system is unusable until reboot.
dmesg logs this:
while using 10.14.5 video proc says it doesn't do hardware hevc encode or decode, however i'm able to play "jellyfish-400-mbps-4k-uhd-hevc-10bit" fluidly using ~15% CPU and probably 20% GPU, so it would seem that the detection system isn't perfect in video proc (this video causes 1100+% CPU usage from VLC in 10.13.6 and really isn't playable) as it’s clearly hardware decoding HEVC in 10.14.5.
The interesting thing here is that once this card was installed I can now use AirPlay to extend desktop to AppleTV, giving 6 total displays, 5 using a mix of DP/HDMI/DVI + 1 AirPlay.
Does this also give the real Mac Pro the ability to use AirPlay?
I can't try that as the 3,1 i have won't run this card, although I could probably change smbios to macpro5,1 to test on this machine.

just my report......bought a Sapphire RX vega 56 on ebay to replace the old AMD RX480 in my Mac Pro 4.1>5.1.
Installation was easy and I activated the hardware accl as described in the first post of this thread.
My primary use is FCPX and it is working fine, Im just editing a wedding highlights video for a client and its all as smooth as butter. The timeline used to stutter a bit when I pressed play but now its all good.
The next test will be an edit of a 5 cam multicam clip and export to mp4. I'll report back if there are any problems...

Many Many thanks, starting to lose rag with lilu not loading but once did the innie and repeated then fine
Now able to use Handbrake for 1080p recording of Das Boot at 3:19 down fro. 2:30hours to 45 minutes
Over 480% CPU on Mac Pro but still a big improvement.
Thanks to everyone that worked on finding and documenting this
what config do you need to set in handbrake to get this to work?
I tried doing some test encodes to both h264 and h265 from both kinds of source material and didn't see GPU being used at all, just CPU >1000%
I use an apple tv 3 preset ( pulled through upgrades ) and then under 5e encoder select the h.264 videotoolbox option rather then x264.
Then simply click start
I'm confused about the use of the word "RAW" in the article. What is RAW H264 and RAW HEVC? Never heard of those before. Can H.264 and HEVC be RAW at all? If "RAW" in this context means "not inside a container" as in not muxed yet etc, then if it's in an MP4 container (which is the most common standard), it certainly can't be RAW, right?
To add some good numbers here. I'm on a 2010 MacPro 5,1 with dual 8 core xeons, 48 GB of ram, an RX 5580 (Saphire Radeon Pulse) and MacOS 10.14.5. After installing Lilo (v1.3.6) and WhateverGreen (v1.2.9) I'm definitely getting h.264 and HEVC decoding but what's better (since I do a lot of video editing) is the h.264 encoding speed in Compressor now. Using the standard Vimeo (up to 4k) setting on a 1 hour long FCPX ProRes 422 video my encoding time has dropped from just over 1 hour to 23 minutes. Loving it.
Now, how the heck do we report back to the WhateverGreen team that their v 1.3.0 upgrade that does not enable pegasus chips by default actually breaks this great functionality. They don't have issues allowed on their git repo
edit: changed whatever green versions to correct versions.

Getting this in Terminal at step 13 -
Mac-Pro:~ gianluca$ sudo kextcache -update-volume /
Warning: /AppleInternal/Library/Extensions: No such file or directory
What is the issue? :/
