I am using a 4 video-in capture board that uses WDM drivers (it could be a 16 video input too). The component I am using to get the video source is simple, it connects to the driver and works fine but that kind of capture board acctually process the 4 video input by dividing the frame rate, the composite signal is not full frame per input, if the board is configurated to work with 30fps it means that each video with work with 7.5fps because the chipset limitation (some board uses 4 chipsets to enable 16 camera input). The result is that you will see a flashing of 4 videos, each one from its camera connected. My trouble is how to separate that signal :( Any body knows a component or a way to handle that? Thank you!

The V2.1 Beta 1 has enchanted video capture component. Cheers, Boian Mitov Magno wrote: Quote: Hi all, I have to develop a simple software to capture video.

I download at least 3 times and no success. Could you check? Btw, how could I broadcast the incoming video via internet? Is there a way to allow that? Thank you!
