Do you have hardware H265 decode?
Okay, I've lost Quicksync and everything, not even a h265 decode :/ Please advise. Tried "sudo codesign --deep -fs - AppleGVA.framework" and chown (after copying the framework from a combo updater), but to no avail, still no hardware acceleration.

Try running this:
Code:
sudo update_dyld_shared_cache -force
then rebooting
and then run it again, and reboot again.

(also you might want to set ig-platform-id to 0x19120001 in clover, )

Did not work, I followed the instructions, then tried to replace the framework again, got through the terminal commnads. But again, the same result.

Code:
2018-02-05 15:15:05.600 VDADecoderChecker[805:13115] Cannot find executable for CFBundle 0x7fae9140f520 </System/Library/PrivateFrameworks/AppleGVA.framework> (not loaded)
VDADecoderCreate failed. err: -12473
An error was returned by the decoder layer. This may happen for example because of bitstream/data errors during a decode operation. This error may also be returned from VDADecoderCreate when hardware decoder resources are available on the system but currently in use by another process.

What OS version are you on?
It looks like your AppleGVA.Framework is corrupted. (Possibly taken from an updater source instead of a full OS install?)

macOS 10.13.3 (the latest one)

However, I got the framework from an update. Can use from a 10.13.2 install, but the date is the same. Will try and then report. Thanks for your suggestions.

It's happened to me where I replace appleGVA.framework from an update, and it only has the changed components of the framework, not the entire framework itself, and had to go back to a full installer to get the full framework.

And I assume you've done the
Code:
sudo update_dyld_shared_cache -force
and reboot process twice?
