I am in the process of building a custom application that requires frame grabbing from an analogic video stream from a TV. I therefore have bought a Hauppauge WinTV HVR 1900 usb frame grabber. It works perfectly with the bundled software, but I cannot make it work with my own soft (see related stackoverflow question here), and I was therefore wondering if there was any kind of frame grabber on the market directed towards custom software (i.e providing SDK, or indications as to how to develop compatible software).
Can anyone point me towards such hardware? I would need a frame grabber with an integrated hardware encoder.
