NVENC hardware with dense optical flow support not present

Robotics & Edge Computing Jetson & Embedded Systems Jetson AGX Orin

I install vpi2-dev on my Jetson AGX Orin (Jetpack 5.0.1), build and run /opt/nvidia/vpi2/samples/13-optflow_dense, then I got this error: “VPI_ERROR_NOT_IMPLEMENTED: NVENC hardware with dense optical flow support not present”.

So, does AGX Orin support dense optical flow? or just the sample 13-optflow_dense needs update? hopefully.

Hi,

Please check the below document for more information.
https://docs.nvidia.com/vpi/basic_concepts.html

NVENC-based dense optical flow is only supported on the Jetson AGX Xavier series.
Orin has a specific HW called OFA for the dense optical flow, however, it is not supported by VPI yet.

Thanks.

Since VPI-2.014 still don’t support OFA on Jetson Orin, Is there any plan to support?
One more question, do you have another tool or SDK, besides VPI, to use OFA?

Hi,

OFA’s support is in our future plan.
Currently, VPI is the only library that will support OFA on Jetson.

Thanks.
