well, I turned off iGPU in the bios (memory set to AUTO that fully disables it), and used the .kext while still keeping with the same SMBIOS(iMAC 19,2) so not to mess up my Apple account and messages, hand-off, etc and DRM issues are also gone when using Safari.
I'm not too sure on the full implications yet with iGPU being disabled(apart from sidecar that just gives a black screen saying connecting on my iPad pro due to it needing a T2 chip or Intel iGPU), but with regards to hardware acceleration VideoProc is saying it's now using my AMD RX580 on both HEVC and H.264, but not too sure this is the case in Final Cut Pro looking at the dGPU usage. Some strange results with Final Cut Pro using different codecs(h.264,HEVC) that are supported on a RX580: very low CPU and low GPU, or high CPU, and low GPU. It looks like some codecs are being passed to hardware and others software, but does not appear optimised. Anyone got experience in this area?
Hi @phonic2k, I'm also using iMac19,2 but can't get VideoProc hardware acceleration/DRM on Safari working with this kext & iGPU disabled in BIOS.
What are your boot args? Do you use any shiki flag?
What are your config for iGPU? Is it still headless?
