Yes. I get 300fps decoding 8k ProRes on a 4090 and barely 50fps on a Zen 3 with all 16 cores running.
The CPU doesn't touch anything, actually. We map the packet memory and let the GPU read it out directly via DMA. The data may be in a network device, or an SSD, and the GPU will still read it out directly. It's neat. |

packets from where, exactly?
another POV is, all the complexity of what you are doing, all the salaries and whatever to do this prores thing you are doing, is competing with purchasing a $1,000 mac and plugging a cable in.
if your goal is, use a thing in the Apple ecosystem, the solution is, the Apple ecosystem. it isn't, create a shader for vulkan.
i didn't say that streaming prores 8k doesn't make sense. even if it were 60fps. i am saying that it doesn't make sense to do product development in figuring out how to decode this stuff in more ways.
