Topic: To define program microphone presence in the webcam
The camera can have a microphone, can is not present. By means of DirectShow it is possible to receive the list of all cameras and microphones on a computer. In case of camera Logitech it is possible to scan the list of microphones on a camera title and on a title to find its microphone. It is not applicable for cameras of other vendors, not always in a microphone title there is a camera title. Perhaps who knows more convenient method to make it. In general any ideas.
