i conect camera on first input , and i got picture on all
I found this, and I think that was with me the case as to make the card or the program that shows me different entrances
"BTW Bt8x8 chip based cards often provide crossbar, ie. multiple physical input connectors and ability to choose by software which input to capture video from. And the driver mentioned by rory has support for this feature.
Since there is a variety of Bt8x8 based video capture devices, the back panel of a card may have one S-Video and one Composite connector, or two Composite connectors, or four composite connectors or other configuration.
The actual input connector used for capture is selected by software but it is also possible to switch continuously and thus emulate capture from 2 or more video inputs using one capture chip (ie. to share total capture frame rate between input connectors). Our latest release of our LuxRiot software supports this natively and shows each physical input as an available camera. There are also DirectShow filters availalbe for this feature.
