Have you ever tried to produce live content simultaneously into more than

is an ActiveX control for connecting multiple capture/encoding filters to a single
Video-for-Windows window. It overcomes the limitation of having only one application

It provides easy to use interface for handle manipulation. The product is intended for
for use with any ActiveX container (VB, ASP, Access, Delphi, etc.) and allows the creation
of unique video applications.
