Nano not using GPU with gstreamer/python. Slow FPS, dropped frames

I compiled OpenCV with gstreamer using this script JEP/install_opencv4.5.0_Jetson.sh at master · AastaNV/JEP · GitHub

When I execute: CUDA_VER=10.2 make, I got:

Compiling: gst_cv_gpumat.cpp
g++ -I/usr/src/tegra_multimedia_api/include -I/usr/local/cuda-10.2/include `pkg-config --cflags gstreamer-1.0 opencv4)` -c gst_cv_gpumat.cpp -o gst_cv_gpumat.o
gst_cv_gpumat.cpp:6:10: fatal error: nvbuf_utils.h: No such file or directory
 #include "nvbuf_utils.h"
          ^~~~~~~~~~~~~~~
compilation terminated.
Makefile:48: recipe for target 'gst_cv_gpumat.o' failed
make: *** [gst_cv_gpumat.o] Error 1

I checked and the folder /usr/local/cuda-10.2/ exist.

How can I compile gst_cv_gpumat ?

Hi,
Please modify this:

-I/usr/src/jetson_multimedia_api/include

tegra_multimedia_api is changed to jetson_multimedia_api in later releases.
