Camera widget is missing basic and necessary features

The problem This is such a obvious problem that I'm unsure if I'm actually blind or not...

So, I want to have multiple cameras connected, and be able to specifically select or at least cycle through the connected cameras.

The problem is that (to my knowledge) there's no way to even see how many cameras are connected.

So the only way to cycle through cameras would be to count up the camera index, and reset the index once an exception has occured. But I'm unsure where I would even catch that exception, given that the traceback sometimes doesn't lead me anywhere, so I don't know where to place the try except statement.

Of course, it would be MUCH better to be able to open a specific camera, or even be able to see if a specific camera is connected at all.

Possible solution

• Knowing how many cameras are connected, maybe even what cameras are connected
• Accessing a camera with it's address or something like that
