Hi,

You will need to install DeepStream SDK first.

After installation, please update the deepstream source folder to the config file.
Thanks.

Thank you.

How to update the deepstream source folder to the config file?

By the way, the DeepStream SDK3.0 seems not support Jetpack4.2.

Hi,

YES. You will need to reflash the device with JetPack4.1.1.

After installation, please update the path here:

Thanks.
