Thanks for your update, i followed your guides on 10.14.3Mojave 10.14.4 (18E174f) update
Still no native GVA support for AMD RX4XX/5XX, need dummy141 kext to enable AMD GVA support.
AMD GVA H264 export work, as fast as IQSV, need SMBIOS support hwe420 like iMacPro1,1, still have bug but stable, output H264 video may sometime discolouring.
QT screen recording work with AMD GVA H264 acceleration.
VideoProc detect HW acceleration correctly, no longer freeze.
AMD GVA HEVC work, fast and stable.
Tested with RX570 + i3-7100 and RX460 + Pentium G4560 on Mojave 10.14.4 18E174f

1. put dummy141.kext to clover/other
2. Edit /System/Library/PrivateFrameworks/AppleGVA.framework/Versions/A/Resources/info.plist, remove hwe TTOnly bwLimit0 bwLimit1.
3. cd /System/Library/PrivateFrameworks/ ; sudo codesign --deep -fs - AppleGVA.framework
4. sudo codesign --no-strict --verify /System/Library/PrivateFrameworks/AppleGVA.framework
1230 v2 + RX560 + Macpro6,1 SMBIOS, H264/HEVC decoding worked, but after a while of watching several videos, system freeze.
Here you say "AMD GVA HEVC work, fast and stable." on 10.14.4, does this mean it won't freeze no matter how many and what kind of videos you watch or export?
