Get a picture using video grabber device

Hi, I need to convert my video signal, using an AV-Video cable. Therefore I have used Video Grabber, link:

The problem is that I get black screen and no picture.

I have tried with example code, and the Processing program sees that a device is connected but does not show any image. Does anyone know what to do or knows about another device that may be detected by Processing?


  • maybe your drivers are out of date. Try to update, this might be a reason why the picture may not appear

  • Thanks for reply. The latest drivers from the manufacturer is updated. However, Windows does not recognize the device, it is located as unspecified in devices and printers.
