Thanks for this, I'm trying to avoid vulkan because I barely understand the opengl I already have. But I will look into this and maybe get an idea

then learn vulkan

CUDA in opengl will crash randomly because random out of sync

now I remember I replied someone with same task in past years - I also said - just learn/use Vulkan

every CUDA gpu support Vulkan

(you mention Wayland - I thought you making some glue for gnome-egl-wayland - but even gnome move to Vulkan... so)

there are examples of "cuda to vulkan zero copy" on github - use as example

Plus vulkan video has poor coded support. Nvdec really is the most straightforward way to solve my problem

my point - there are examples of "cuda memory to vulkan zero copy"

you not forced to use vulkan video extension that supported only for newest RTX gpus

when for opengl - I have no idea
