cudaNvSciBufMultiplanar - CUDA NvSciBufMultiplanar Image Samples
Description
This sample demonstrates CUDA-NvSciBuf Interop for Multiplanar images. A YUV 420 multiplanar image is flipped and allocated using NvSciBuf APIs and imported into CUDA with CUDA External Resource Interoperability. A CUDA surface is created from the corresponding mapped CUDA array and again bit flipping is performed on the surface. The result is copied back to a YUV image which is compared against the input.
