[jitter] video mixer with vga input card

Hello,

I am searching a solution for the following problem:

I  need to build up a small video mixer with two video inputs and an audio input
One input should be a normal composite-video input which captures the material of a video-camera and the other should be a vga input.
What I need to do is a picture in picture mix of the two sources and save it together with the audio on hard-disk.
The vga source comes from a vga input card.
Is there a specific device-object which can handle the vga input card?
Maybe someone has a good tip or knows a similar project?

Best regards


Daniel
