I'm having an issue where Action will record video and audio perfectly, but no matter what settings I adjust or which USB port I use, it can't get a signal from my webcam. Other applications can access it normally, and action is the only program to have this problem. If it helps at all, it is a Logitech HD Pro Webcam c920. Everything I've found on this subject is severely outdated, and the email I send to support was not responded to.
Thanks.
