After upgrade to the last copy of Chrome (60.0.3112.90) the Flash Settings hasn't shown any camera in the Camera tab.
Before upgrade the Flash worked well.
I don't have any problem with this Flash for other browsers: Internet Explorer, Edge and Firefox
MS Windows: 8.1 (x64), 10 (x64 and x86) version 1703
Chrome (x64 and x86) version 60.0.3112.90
Adobe Flash Player 220.127.116.11
Chrome now requires that all content requesting camera/microphone access be served over HTTPS. This includes Flash content. If the content is *not* served over HTTPS, then you won't even be presented with the Chrome's camera/microphone permission dialog. Since Chrome mediates access from Flash Player to the Camera/Microphone dialog, this means that the camera will not be visible to Flash Player.
