I am writing a custom plugin that needs t run an algorithm in a cuda kernel. I use the NvBufSurface API for getting a hold of the NVMM (a frame buffer from nvarguscamerasrc) without copying it. I now would like to use that same buffer with a cuda kernel. Is there an API for this? Is there exampl…

Hi, [image] elhe: Ok thank you @DaneLLL . When I have mapped an egl image. How can I use it with a custom kernel? In the patch you posted, the eglImage gets converted using opencv and unfortunately not a custom cuda kernel. This should be resolved per SIGSEGV when accessing CUeglFrame pPi…
