I would kill to find a video decoder that can also output the motion vectors. That's super useful for using video streams in videogames, if you're using things like DLSS....

Thanks for the tip, I noticed that project a while back and how it would be suitable, however I've already implemented a working pipeline for vulkan video with explicit MVs...

vk_mini_samples ser_pathtrace works (EDIT: **no it doesn't**, it only _appears_ to work), but I tried it in this repo and VK_NV_RAY_TRACING_INVOCATION_REORDER_EXTENSION_NAME isn't available. I'm guessing it just isn't implemented or...

https://github.com/nvpro-samples/vk_mini_samples/tree/main/samples/ser_pathtrace This repo uses GLSL as its shader language. I wonder if HLSL via DXC or Slang is the culprit for this repo not supporting SER @natevm have you heard...

Ok, progress, it was missing from the requested enums, that's why it didn't show up in the listed / enumerated ones:   Ok, now it shows up as supported...

However, toggling SER in Vulkan mode makes no difference to the framerate whatsoever.  

DX12 jumps from 13.6 to 21.8 FPS  

Looks like there's another show-stopper problem, potentially:  I enabled USE_HIT_OBJECT_EXTENSION define for SPIRV / Vulkan builds, but it crashes during pipeline creation  Looks like SER extensions don't work...

That's exactly what I was hoping would work! Yay, so I don't have to abandon HLSL. Still, it would be nice if this repo used SLANG for VK / SPV...

I would very much like to know if I can use my current HLSL shader, with some slight modifications for SER, and slangd to compile it, to activate SER on...
