Connecting an Epiphan DVI2USB 3.0 frame grabber to MITK via OpenCV does not work as expected. If a new video device is created by using the Ultrasound Support view, the image stays invalid. There is the following workaround to get it running if a webcam is also connected:
1) first create a new video device with the port of the web cam and start it
2) create a second video device with the port of the frame grabber and start it,Sometimes the images stays black after connecting to the. too.After disconnecting and reconnecting it usually works, It works in this case.
but sometimes it takes several reconnects until it works.
