Yes, 'yuyv422' at least not returned any errors, but just verified 5 fps from the encoded file
ffmpeg -hide_banner -f video4linux2 -input_format yuyv422 -i /dev/video0 out.mkv
ffprobe -hide_banner out.mkv Input #0, matroska,webm, from 'out.mkv': Metadata: ENCODER : Lavf58.76.100 Duration: 00:00:12.40, start: 0.000000, bitrate: 2 kb/s Stream #0:0: Video: vp9 (Profile 1), yuv422p(tv, progressive), 1920x1080, 5 fps, 5 tbr, 1k tbn, 1k tbc (default) Metadata: ENCODER : Lavc58.134.100 libvpx-vp9 DURATION : 00:00:12.400000000
Any idea why the audio:0kB from '-codec:a pcm_s16le' disappeared in the encoded files?

I think for audio you need few more alsa switches:
https://askubuntu.com/questions/1451630/hdmi-capture-card-macrosilicon-ms210...
something like this but find/use your own alsa device :)
What I feel unused to is the need to set ffmpeg code both Audio and Video input format and input device respectively. A couple of syntax examples for audio found:
ffmpeg \
-f alsa -ac 2 -i hw:CARD=HDMI,DEV=0 https://trac.ffmpeg.org/wiki/Capture/V4L2_ALSA
-f pulse -ac 2 -i default https://dev.to/ethand91/how-to-record-webcam-video-and-audio-using-ffmpeg-41...
Suggestions here what to use from the listing below?
try -f pulse -i default, (or sysdefault) because your system already set it up as first rec. device?
for -f alsa try -i hw:CARD=MS2109,DEV=0
default audio should be 2 ch/48khz pcm
And the latter fit with my used encoding syntax?
I hope yes!
ffmpeg \
-codec:a pcm_s16le
Now I will disconnect the Blu-ray burner from its USB3 port on the backpanel and reconnect and retest Video capture there.
good luck, while I suspect for this specific device it will not improve framerates much due to chip used.
but please share your actual results!
Then i have run through the same test cycle. I could actually have stopped already after running "v4l2-ctl --list-formats-ext" with regards to the fps. Yet I updated the encoding syntaxes and got the audio streams seemingly recorded. But for some some reason I could not hear any sound in my airphones.
check input levels in mixer?
Tried the Alsa mixer. Audio works for other video files like DV with PCM, som also the Alsa mixer volum slideer. But not with the recorded Pulse default audio.

Trial_3_ with ALSA Audio input instead finally playbacks the audio !
As seen from mediainfo output below, the FFV1 1920x1080 video stream with 5 fps makes up 94%, the PCM audio 3% In comparision the FFV! 720x576 video stream where the Hama ms2109 capture manages 25 fps, the sizes are 95% and 3% -------------
I attached incorrectly encoding syntax for v210. The correct syntax with FFV1 in this case is ffmpeg -hide_banner -f alsa -i hw:CARD=MS2109,DEV=0 -f v4l2 -framerate 25 -video_size 1920x1080 -i /dev/video0 -codec:v ffv1 -level 3 -codec:a pcm_s16le -f matroska 1920x1080_3_ffv1.mkv
ffmpeg -hide_banner -f alsa -i hw:CARD=MS2109,DEV=0 -f v4l2 -framerate 25 -video_size 1920x1080 -i /dev/video0 -codec:v v210 -codec:a pcm_s16le -f matroska 1920x1080_3_v210.mkv
ffprobe -hide_banner 1920x1080_3_ffv1.mkv

Is 4KVC00 from "V AV access" still the best option as replacement?
Well, at least they have english-speaking site, so you can ask few tech questions there?
But you can try to chase some of those new ms2130 (!) devices ....
some ppl on videohelp forum use avermedia's usb unit for attempted 576i capture, but device outputs pseudo-progressive, so for recovering interlaced signal you need some processing anyway ?!
https://forum.videohelp.com/threads/406125-Panasonic-DMR-Avermedia-Extremeca...
also, as timesink you can check ld-decode thread in same subforum, project definitely alive but requires real hardware mods to vcr and yet another capture card for capturing raw RF signal from tape head!
Thanks for useful help!
see https://patchwork.kernel.org/project/alsa-devel/patch/20200702071433.237843-...
Also, ms2109 confirmed .. :(
