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 30 fps instead of 60?
Like this?
But shouldn't a 422 and not a 420 output format be created?
it seems in some cases ffmpeg not geared towards preserving most
information, just picks up most commonly defined/first pixel
format. Try mpeg2video as output codec, and/or specify pixel
format (pix_fmt) more explicitly before output's filename?
Could you possibly examplify the latter?
If things work as hoped in another thread, I want to test if analog
Hi8/S-video directly to digital DVD-Video.mpg and SD-BD-Video.mpg is
possible.
That is bypass the extra step to DV format conversion and compression.
Also you can try 'copy' video codec and meet absolutely enormous
test file.

Alsa identifier for ms2130?
I'm ready to test with the analog camcorder connectedto
A/D-adapter + ms210 capture, but first a question about the Alsa
hw: identifier for the latter.
For the Hama ms2109 I used
ffmpeg -f alsa -ac 2 -i hw:CARD=MS2109,DEV=0
For ms2130 UHD card
arecord -l
**** List of CAPTURE Hardware Devices ****

arecord -L
.....

Default Audio Device
front:CARD=UHD,DEV=0
USB3.0 UHD, USB Audio
Front output / input
Suggestion to
ffmpeg -f alsa -ac 2 -i hw:?
===
just omit hw alsa part (but not -f alsa) so it defaults to sysdefault ? :)
also, try 3:0 (card 3, subdevice 0)
also, may be try /dev/snd/pcm*c devices
1) Test to generate a fake alsa audio file with ms2130
ffmpeg -hide_banner -f alsa -t 30 out.wav
Output #0, alsa, to 'out.wav':
Output file #0 does not contain any stream
That is, it doesn't work without identifying ms2130 card#3, because
there ar sysdefaults for each card I expect
