I would like to use the built-in webcam on my laptop and a USB cam at the same time for my presentation.
The internal webcam should show me, in a second picture the USB cam should show what I'm doing. Is that possible at all? And if so, what software can I use to do this?
I once experimented with OBS Studio. It worked quite well, and with a plugin, the name of which I have now lost, you could even output the result on a virtual webcam and then set it as the source in Teams / Skype / Zoom / etc.
Should every meeting be able to use software, I mostly use teams, you can see my picture and, depending on the desktop size, you can show the window with your cam and other windows at the same time
I use the Camtasia program to record the activities on the screen (but for free). A webcam can be displayed as a picture in the picture.
But as I said, it is a screen recorder and not a real second camera.
