From a testing report on the JavaCV changes, running on Windows 10 with an internal camera and a USB web camera:
It works for me, on my laptop, but only lets me use the integrated camera and not the external USB one I use when docked. I can selected the other camera, but it always defaults back to the integrated camera for some reason. Not generating any kind of error messages though. One is named "integrated camera" and the other is "HP USB webcam"
