PPCnostalgic Posted November 13, 2020 Share Posted November 13, 2020 Good morning. I tried to browse about 3 days looking for a compatibility answer for my (old) rig. So can someone tell me if it's possible to enable HEVC + H265 hardware acceleration on this machine? I'd like to hear an answer before i'll give up please. The system lists the card properly and Metal is supported. MSI X79A-GD45 Xeon E5-2696v2 16Gb DDR3 Powercolor Red Dragon RX 580 8Gb (it's not the infamous SP 2048 version) Mac OS 10.14.6 Thank you!

PPCnostalgic Posted November 13, 2020 Author Share Posted November 13, 2020 Thank you Hervè. Using iMacPro1,1 SMBIOS the software lists HW acceleration but doesn't lists the video card (see attachment). Tried to encode a movie but despite I could enable HW acceleration the conversion was cpu only, the video card was idle. Link to comment Share on other sites More sharing options...

PPCnostalgic Posted December 30, 2020 Author Share Posted December 30, 2020 No, I switched back to Mac Pro 6,1 to be more accurate with my hardware. Honestly I think GPU hardware acceleration won't do more than CPU, a Xeon E5-2696vs with 12 cores. BTW: I tried Opencore as well but nothing changed.

jmvBMW Posted December 30, 2020 Share Posted December 30, 2020 ok, I did some research and found this thread https://forums.macrumors.com/threads/activate-amd-hardware-acceleration.2180095/ According with the author, it's just a Videoproc cosmetic error, which expect the word "AMD", instead our graphics card says "Radeon" He says that it can be changed using opencore (and clover i guess), but I don't know how Link to comment Share on other sites More sharing options...
