<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
ms2130 HDMI-USB3 UHD capture card alone, for what they
are worth.<br>
<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>

As the above doesn't list any 1920x1080 resolution, I
wonder if it list just format for the usb2 webcam and
not for ms2130 capture card?<br>

<div dir="auto">Yeah, looking at how webcam listed first it
makes sense. Try to instruct v4l2-ctl to use another device?
(my guess it will be "-d" switch but I can be wrong! Manyal or
"--help" output is better guide ..)</div>
</div>

<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>
