I have two webcams connected to my Win10 PC. Both show up in device manager as "UVC Camera" (both are based on raspberry pi with the ovc-gadget tool). Only one of the cameras shows up in the PointTracker list where I can select cameras.

I've tried changing the "friendly name" of one of the cameras through regedit and that name shows in the device manager now. Still only one camera is available in the Point Tracker camera selector dropdown list.

It seems to be from reading the code that
a) cameras are identified by their name so if one has two cameras with the same name, only one is available
b) its not the device friendly name that is used but the name of a "filter"(?) that is used.

Are there any unique identifiers other than name that could be used that would enable me to select the right camera?
