Only a single webcam is supported

[buffcode]

I have connected two Logitech C270 to the USB ports on the back. The UI also shows two connected cameras, but the video is always from the first camera, so you have two cameras showing the same image.

It seems, as if the rtsp_demo binary is always using /dev/video0 and won't start up another process for further cameras.

Two cameras connected, Sonic Pad is showing two images (both from camera 1).

I would expect it to behave just like written in the Mainsail docs:

The current system only supports the display of a video stream (for time-lapse photography / AI detection / IOT monitoring), more than 1 video stream function is temporarily in a more backward planning time
