Hi All,

I downloaded the optical flow SDK and its dependencies from

and successfully built it.

However when I run
Optical_Flow_SDK5.0.7/NvOFBasicSamples/build/bin/x64/AppOFCuda
I have the error:
“NVOF library file not found. Please ensure that the NVIDIA driver is installed”
Traced back to the source code in Comon/NvOF.cpp, I found and verified that there is no libnvidia-opticalflow.so.* in my machine.

So my questions is how to install this lib?
Thanks,

Hi,

The library is integrated in the dGPU driver so it’s not available for Jetson users.
We want to enable a similar issue with the VPI library which will be released in the near future.

Thanks.
