It would be best if you posted some code to show us how you're currently getting the first video device. Although there is a project to get DirectShow working in .Net. Look at question 8 ("can I work with multiple video devices at the same time?") on this page, which shows how you would work with extra video devices, at least using that library (if that's what you're looking for, you could download their code and see how they implement that call to DirectShow).

Solution 2

yes there is a function or lines of code to calculate all camera which are connected to the computer. i used it and of course changed it to work with my project. but it has a problem and it is that each time you use this code it binds the last video device to the program. although it suffers from some capability but it the best that i could find!!!.

if you want i can post it here.

Hi, you need to select a capture device. See: http://msdn.microsoft.com/en-us/library/windows/desktop/dd377566(v=vs.85).aspx I'm intreasted to see how you get the video preview stream. Because I want to see what others are coding dor that. My codes have error when I captur several devices at the same time. Could you post it to let me see?
