Frame lost while saving videos from camera using jetson nano B01

Hi,
If your use-case is to use CUDA filters in OpenCV, we suggest use jetson_multimedia_api + mapping NvBuffer to gpuMat. Please check this patch:
LibArgus EGLStream to nvivafilter - #14 by DaneLLL

And please check VPI functions:
VPI - Vision Programming Interface: Main Page

We support some CV functions in VPI, if your use-case is included, please try jetson_multimedia_api + VPI.
