Avermedia HD Capture: no video when capturing the HDMI input
The problem is the “VideoInput” index of the driver that does not match the real input, use Select “SVIDEO” instead, e.g.:
VideoGrabber.VideoDevice = VideoGrabber.VideoDeviceIndex (“Avermedia HD Capture 1”)
VideoGrabber.VideoInput = VideoGrabber.VideoInputIndex (“SVIDEO”) // to capture the HDMI input
VideoGrabber.StartPreview()
