Register GRAY8 image with cuGraphicsEGLRegisterImage

[michael_gruner]

Thanks @njuffa. For anyone else wondering the same, here’s a thread discussing the same which I didn’t find before. Basically GRAY8 is not supported (yet) in the EGL side.

cuGraphicsEGLRegisterImage and NvBufferColorFormat_GRAY8

Hi, Thanks for your question. Based on our document, there is no CUDA_ERROR_NOT_SUPPORTED return type in the cuGraphicsEGLRegisterImage. https://docs.nvidia.com/cuda/cuda-driver-api/group__CUDA__EGL.html#group__CUDA__EGL_1g9f9b026d175238be6f6e79048d6879c5 Would you mind to share a simple reproducible source so we can check it directly? Thanks.
