When try to run the VPI 1.1 sense optical flow sample https://docs.nvidia.com/vpi/algo_optflow_dense.html, encountered the following error:
VPI_ERROR_NOT_IMPLEMENTED: NVENC hardware with dense optical flow support not preset
Dose that mean the Jetson nano GPU dose not support hardware accelerated optical flow calculation?
What GPUs support NVENC hardware with dense optical flow ? Is it true only the Turing and Ampera GPUs support hardware optical flow?
