I've been working on an encoding test with Netflix's Meridian test sample available on xiph and decoding that thing is a best. it's 4k JPEG2000 @ 59.94fps and I have never seen a system that could play it back, i.e. decode it, in real time.

Same thing with the ToS sample, it's 4k dci JPEG2000 @ 24fps and that's another one that I have never seen a system that can play it back in real time.

I checked, it doesn't look like either NVIDIA or AMD have a video card with hardware decoding of this codec, I also checked Apple's new M1 chip and it seems that may support it:

This lists hardware encode support for VP9 (!) and JPEG among other things and I know that it's the only consumer chip currently available that supports hardware decode of HEVC 10-bit 4:2:2, so maybe it supports hardware decode (and encode?) of JPEG2000, but on the PC side I am wondering what kind of hardware (cpu) it would take to play back these files in real time, i.e. smoothly.

If anyone has had any luck with either, please post here.

Thanks.
