So I have received the ms2130 HDMI-USB3 capture card.
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.
Yet, I have initially run some verification tests on the ms2130
HDMI-USB3 UHD capture card alone, for what they are worth.
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".

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?
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 ..)
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.
Obviously there is a default (or first device) used, when no device is
specified, so thank you for the tip.
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:
v4l2-ctl -D -d /dev/video2 --list-formats-ext

Try also ffplay to list supported formats for a video4linux2 device:

try 30 fps instead of 60?
Like this?
But shouldn't a 422 and not a 420 output format be created?
