How do I receive camera data with GPU using Jetson nano?

I would like to know about Jetsno Nano

we use Jetsno Nano for image processing.

it goes through the Memcpy process of copying memory to move data from the CPU to the GPU.

However, this process takes a lot of time,

so is there a way to receive data directly from the camera to the GPU?

Hi,
If you use v4l2 interface to capture frame data, you can refer to this sample:

jetson_multimedia_api/samples/v4l2cuda

It shows hoe to capture data into CUDA buffer directly.
