Hi, thank you for the info. I will start learning about vulkan-cuda interop.
My goal is to produce "video texture" that gets updated each frame (if FPS is limited to 60).
Ideally I would like to avoid image copy. I don't like CUDA >> system >> vulkan. For 4K resolution this is a lot of overhead.

Hi,
I would like to use opengl calls to modify texture using cuda kernels.
I would usually first make opengl context current to my thread, then get texture id, then register texture as cuda resource, run kernels, unregister cuda-texture and finally include my texture in render loop.
What would be performant method to do this in UltraEngine?

The decoded image is stored in CUDA memory in NV12 or planar YUV 4:2:0 format. memcpy() to texture is required. Color conversion to RGB24 is also required for opengl. Ideally i want color conversion where destination is texture memory.
Great pointer to vulkan-video extensions!
