Hi, I am developing a image analysis software with opencv (runs in both 2.4.11 and 3.0). I use it with webcams without problems but I tried to use a Avermedia C874 video capture device. Under windows the software recognizes "Avermedia USB HD Capture" as a video device, but when I choose it, the function (in java):

  VideoCapture capture = new VideoCapture( -1); 

  Thread.sleep(1000); // Wait for video to start

The call...

capture.isOpened();

returns always false. Does anyone knw a solution to capture frames from this device?

By the way I tried it also in linux and it also does not recognize the board. Thanks for your answers, PN
