  • install ned's connectors before installing VideoFlow
  • To test it drag a box from the objects dialog (world menu >> objects...) and select a video source.
  • Create more boxes with filters and connect inputs with outputs (creating a wire with a click on an input/output)

Known problems with this version

• sqWebCam.dll
