I would like to have inference on more than one camera and use the following:
I plan to use NvBufferMemMap() from nvbuff_utils.h to get the address of the memory-mapped plane as void ** .
But I’m unable to understand what would be the format of the void** memory + whether this address points to the GPU memory or not?
In case my approach is not correct, I would be glad to hear any advice.
It is CPU pointer. Please refer to code about
DO_CPU_PROCESS in 10_camera_recording sample.
For getting GPU pointer, you can check cuda_postprocess() in 12_camera_v4l2_cuda.
Thank you for helping!
What would you advise to use for inference with multi camera?
I have experience with C++ but I’m confused which approach to use.
Any advice will be appreciated.
An existing solution is to use DeepStream SDK. You can check the sample config files in
source1_csi_dec_infer_resnet_int8.txt is for single camera source. You may try it first, to make sure it can be run successfully. And then customize it to 4 sources. May refer to other config files for multiple sources.
