I’m a bit confused over optical flow and xavier nx (I’ve searched for few hours but still confused over what I can do and can’t).
I have a xavier NX and want to run optical flow on it. By reading VPI docs I understood that optical flow not supported in NX, but maybe I misunderstood and it is supported but not on OFA?
There is also a special optical flow SDK, but after reading this question I think it is not relevant in my case.
So my question is: can I run optical flow on xavier NX? and if so, how can I do it and what hardware does it run on?
Based on the latest VPI document, there is a dense optical flow feature that uses NVENC hardware.
Could you check if this meets your requirement?
Hi. Thanks for your reply.
- Where does it say that it can be run on NVENC?
- The docs are for VPI 2.0, while I have jetpack 4.6.1 that comes with VPI 1.2 (Tried to upgrade to VPI 2 using “sudo apt-get install libnvvpi2” in my Xavier but I got “E: Unable to locate package libnvvpi2”). Where can I find the docs for VPI 1.2?
Sorry, you can find the VPI 1.2 document below:
In the ‘Limitations and Constraints’ section, you can find the support of NVENC on Xavier NX.
Only supported on Jetson Xavier NX and Jetson AGX Xavier series.
