Please help me. Thanks.

What is the output when you run ldd /opt/nvidia/vpi1/lib64/libnvvpi.so.1 ?

Is there any output from the following command line?

readelf -s -W /usr/lib/aarch64-linux-gnu/nvidia/libnvmedia.so|grep NvMediaLDCUpdateTNR2Params

@junshengy for your response.

For your system, it should be /usr/lib/aarch64-linux-gnu/tegra/libnvmedia.so

It seems that Jetpack is not installed correctly. Since you are using Jetpack Nano, try the following link

https://docs.nvidia.com/jetson/archives/jetpack-archived/jetpack-461/install-jetpack/index.html

@junshengy

Thanks for your response.

But I have a Jetson nano with third part carrier board, which has its own BSP.

DS-6.0 is compatible with Jetpack 4.6.1 GA

Here is the compatibility table.

https://docs.nvidia.com/metropolis/deepstream/6.3/dev-guide/text/DS_Quickstart.html#id5

You need to consult the supplier.

@junshengy

Jetpack 4.5.1 does not support deepstream version 6.0.1. I switch to Jetpack 4.6.2 and it works. Thanks.
