How to synchronize cameras with nvarguscamerasrc?

Hello! How to synchronize 2 or more cameras via gstreamer nvarguscamerasrc into c++ or python code?
Before I use a single camera with appsink

Jetson xavier, jetpack 4.4, Jetson sdk components are installed

Have a reference to below topic for synced sensors.

syncSensor is example from multimedia api. I can not find tegra_multimedia_api on my jetson, but i’m was install it with jetpack. Where I can find syncSensor and other examples?

You can download the multimedia API sample code from sdkmanager.

Thank You for Your help!
