Hardware video decode

[davidbdyer]

Is hardware video decode no longer possible with High Sierra and Nvidia Pascale hardware?

It's possible, just require lots of trail and error.

Do you know if I'm on the right track with nvidiagraphcsfixup and shiki? Do you know where I could find better instructions than the faq for those two plugins?

What do you mean by "decode?"

If you mean "standard" playback (DRM issues), then Lilu + Shiki should solve it.

I tested yesterday and I'm not having DRM issues on iTunes. I use plex and not iTunes 99% of the time anyway. What I mean by hardware video decode youtube for example on my MBP doesn't have a CPU process for video decode the GPU is doing it. On my Hackintosh, my CPU is doing the decoding, and it's using a significant amount of CPU. 20%-80% depending on the resolution.

Ah. Not sure how to answer that one for you.

It appears that it depends on the app. Watching a YouTube video in 1440P in Safari shows no process running on the CPU. Watching the same video in the same resolution on Chrome shows a CPU process at about 65% usage.

I use neither of these. For my Intel GPU I only have the attached SSDT file in EFI/CLOVER/Acpi/Patched. In my config I do not have any ig-platform-id and am I am not injecting Intel.

I think with Chrome you can chrome://flags/ and enable overrides the built-in software rendering list and enables GPU-acceleration on unsupported system configurations.

I don't know how to generate an SSDT for my iGPU can I use the one you linked? Will I need to drop any tables for it to work or will it conflict with the SSDT file I made with the piker-alpha script for my CPU?
