[Solved]Fixes to Get Full Acceleration on Intel HD Graphics in iMac 17.1

[xelanaiznac]

damn, another tricky issue.
using compressor standalone, quick sync is not working with Nvidia (it is with Vega for example)

neither if I use Final Cut and then send to compressor option.

meanwhile finalcut is working perfectly with quick sync



edit:
QuickSync with Nvidia and compressor is working only if you use hevc (h265). if you use h264 quikvcsync is not working.
not a big issue, imho

This may be the wrong thread but I'm hoping someone can point me in the right direction. Ive got lilo and whatevergreen and since installing ive had serious issues with final cut. Im getting green artifacts that cover the entire piece of footage every time i try to render with FCP or compressor. Even background render ruins it while im editing. It could be an acceleration issue but im not sure. Internal GFX is enabled and inject intel is there. Ive been trying to find what intel IG but they seem to boot to black screen. I found on a different thread to inject 0x59120003 and to use -disablegfxfirmware as well as add a device property 0AAAAA00 but all of these things boot to black screen. Any suggestions?

Just a head's up I've lost Quicksync Encode and Decode as of 10.12.6 (16G1212) (security update 2018-001).
I'm on all the most up to date kexts, and nothing else has changed in my setup.

Edit: rebuilding the DYLD cache twice fixed it.

Hi Guys, I've got HW h265 (HEVC) decode, but h264 is not hardware accelerated. How is that possible?

 

[canyondust]

Do you have hardware H265 decode?

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:

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.

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.
