Virtual camera control/DLL

[tjschilling]

I am looking for a third part control/DLL to run a series of virtual camera's so I can analysis a series of pre-recorded video streams simultaneously. I have downloaded several virtual web cam products, some of which work well for single camera simulation and have send E-mail inquiries on purchasing a control but have only gotten back bounced e-mail messages or nothing at all. Can anyone point me to a control for sale or even better, free?
