I have a iMac computer that serves as a second display for my Windows 10 machine. They are connected on the same internet and network, and physically connected via Displayport(Win10) / Minidisplay (iMac).
I want to use the builtin cam from my iMac as a webcam for my Windows 10 computer.
I can find tons of apps to use my phone's cam as a webcam on my computer, but failed to do the same from another computer.
I understand that this won't be possible using only the display cable (it seems I need several usb-to-usb cables between the two computers), but I can't see why it wouldn't be possible via wifi/ethernet. I tried several apps like EpicoCam which are designed to do exactly that, but using a phone's cam. I can't find one doing computer-to-computer.
