USB Cameras and The BeagleY-AI

I am performing some source code tasks and I wanted to be able to track things via USB Camera.

What is holding me back?

Maestro hardware serial interface established.

This application failed to start because no Qt platform plugin could be initialized. 
Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, 
vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.

Aborted

It seems I cannot initialize a QT plugin for whatever reason. Also, it seems client cannot connect to server. I am not sure why exactly this is the case so far.

a reboot made the source code work. Odd days…
