Radeon Polaris - HEVC decoding?

No by default (typical Apple style). The Hackintosh group seems figured out how to activate it, but I haven't seen a real Mac Pro user report success yet.

If I remember correctly, you said on some other thread in this forum that MP with W CPU is quite strong?
Could you, please, let me know up to which hevc test file/bitrate your mac can play without stuttering.

I found that VLC 4.0.0 nightly build seemed to do well when I tested HEVC in a local store on some display m3 machines (well, the CPU supported HEVC, but anyway)...

Depends on the video file. REC 709 color profile plays well, but REC 2020 color profile is still very jerky.
I am up for testing this if you’d like.
We have all kind of cards and Mac Pro configurations.

jellyfish-250-mbps-4k-uhd-h264.mkv, H264 is definitely not an issue. Easy to play the highest bitrate sample. 280-420% CPU uasge.
jellyfish-110-mbps-hd-hevc.mkv, 8bit HEVC is also not at issue. Easy to play the highest bitrate sample. 180-280% CPU usage.
However, for 10bit HEVC, it can only smoothly play up to jellyfish-120-mbps-4k-uhd-hevc-10bit.mkv. The initial 13s is quite demanding, and use very close to 1100% CPU (overall 600-1100%).
Anything at or above jellyfish-140-mbps-4k-uhd-hevc-10bit.mkv, only the 2nd half may able to play smoothly. The 1st 13s is shuttering because running out of CPU power.
That's the W3690.
Oh yeah, forget to mention that's all done by IINA (as you can see in the stat info). Just try VLC Nighty build 4.0, basically provide the same result.
On a 12 Core 3.46GHz + RX 580 everything is smooth, also jellyfish-140-mbps-4k-uhd-hevc-10bit.mkv, although I see the rx580 kick more with the HEVC 10bit.
Might be the difference in CPU though.
On jellyfish-140-mbps-4k-uhd-hevc-10bit.mkv, CPU hovers at 800% and goes down as the clip progresses
Tried on VLC 3.0
Thank you! Could you, please, tell me whether there are any Apple logo issues with the RX 580. It works OOB as I understand. Are there any other issues with this card? Which brand is it? Does HDMI work?
have ripped 4k 10bit bluray film to .mkv with makemkv, and playback with svp4 via mpv (HW:videotoolbox-copy)(frame rate interpolation from 25 fps to 50/60fps), and with rx vega 56 on macpro5,1 running monterey there is a chopy playback with lots of dropped frames. dont know if OC setup is faulty, because on same computer (12core) with windows 11 there is much better playback (but still dropped frames quite alot).
