This patch refactors the CUDA import code to allow for Vulkan images with multiple planes to be mapped. Currently, a driver bug exists which causes NV12 images to be mapped incorrectly when the memory being mapped contains both planes, the issue has been reported to NVIDIA. yuv420p does work correctly, however. This is still an improvement, as the code used to crash when trying to map the memory, unless disable_multiplane=1 was given as an option.
