I have been searching for some answers for this problem, relating to the Amcap.exe and my webcam.
I have come to this conclusion:
With the first instance of the webcam being plugged in and started, all is fine, video works, capture works, etc.
But,,,,,if I disconnect the webcam, and maybe later on reconnect the webcam, the Amcap program freezes (not responding). The only way to unfreeze, is to Ctrl-Alt-Del, to open Task Manager and try to stop program there.
Task Manager, show 2 instances of Amcap (not responding).
So my theory is:
Amcap has not been released from Windows or memory, and the 2nd starting of the program, causes it to freeze up.
Solution:
Before starting 2nd webcam session, or before reconnecting webcam, reboot computer (this will release this Amcap from memory or system), and the webcam will work properly for that session.
Other than that, I have no idea what else causes the freezing
