This is one of the capture dongles I used to capture my camcorder/microscope camera recordings for the YouTube videos I do. It will work on Windows & in Linux, using VLC or my preference, Open Broadcaster Software to record live video. Must use USB 3.0 or else the results will be trash!
This has a microUSB port on it, so I would recommend taping the cable to the dongle so it acts as a strain relief. It still works fine for me. I have two of these, this is the second one.
