I have some magewell USB capture dongles I use for capturing HDMI video from a microscope & a camcorder. Recently I noticed the microscope camera getting choppier and choppier, adn goign in and out all the time.
I tried using the same dongle & same HDMI cable on the camcorder, and it works perfectly fine. So you would assume the microscope camera is bad, right?
I plug the microscope camera into a TV using the same HDMI cable, at the same 1080p/60hz and it works fine. I even smacked it around a little bit for good measure.
If the HDMI microscope camera works with other monitors, and the capture device works with other HDMI sources, I am probably not getting help from either of them. They will just point the finger at the other. I was thinking of getting a PCI express dual channel HDMI capture card that supports V4L so I can try that out but I am looking for any alternative way to troubleshoot my issue without spending $600.
