I think basically all of Intel and NVidias current offerings have hardware 265 decode. But AMD GPUs still only do h.264 (which might be a patent thing, or might just be that their target market doesn't really care. I know I don't, my gaming PC is plenty powerful to just software decode H.265 anyway, although the power efficiency gains would be nice)

The mobile market I have no idea about.

EDIT: I was wrong about AMD - see replies.

mpv also reports "Using hardware decoding (vaapi)." when I try to play an HEVC file.

Ah it looks like I was mistaken, they've had h265 encoding and decoding support for a while. Not sure where my brain got this idea from, I even have an AMD gpu atm.
