              <div> So I have received the ms2130 HDMI-USB3 capture
                card.  <br>
                The A/D AV converter & SV-HDMI/adapter is not
                received so far, and I have not avialable my HDV
                camcorder (on service) to output HDMI video stream with.<br>
                <br>
                Yet, I have initially run some verification tests on the

                are worth.<br>

                As "UHD" (and/or USB3) is mostly generic used to
                identify this card (while ms2130 almost not), the some
                output is piped and stripped with grep "UHD".<br>

    Be aware that "v4l2-ctl --list-formats-ext" was the same (I think)
    as used for the previous ms2109 Hama card, and I thought formats for
    all connected devices were listed then.<br>
    Obviously there is a default (or first device) used, when no device
    is specified, so thank you for the tip.<br>
    <br>
    By help of google and "superuser" I found out that actually both "-D
    -d /dev/video2" are needed to get both frame sizes and fps listed:<br>
