VIC in Jetson Nano

[adityawasnik91]

I have Jetson nano with DS5.

Im trying to enable scaling-compute-hw for nvinfer and compute-hw for streammux, but while initialisation, I get the message that these elements do not have these properties, but they are there in the documentation.
[ nvinfer,streammux ]

my questions are,
(1) Does Jetson Nano have VIC hardware?
(2) If yes, how do I enable it in my elements?
(3)If I use it in nvinfer and streammux ( as the model input size and the stream size is different), will I get any performance boost ?

also, what are the optimal gst-property setting for these elements (Nvinfer, Streammux and nvv4l2decoder) so that they utilise the hardware to the fullest ?

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks

1. Jeson nano has VIC, please refer to https://developer.nvidia.com/embedded/dlc/jetson-nano-system-module-datasheet $1.3.4.
2. You can select the HW to VIC (scaling-compute-hw or compute-hw to 2) to enable it.
3. It depends. The VIC is an extra accelerator for such scaling task thus save the GPU resource for other tasks.
