I tried to Record camcorder video stream via v4l2 and hdmi-usb3
capture as input device.<br>
<br>
ms2130 is more powerful but else similar to the usb2 EasyCap device
example described in the CinGG manual<br>

<br>
My Sony FX7-E 1080i50 HDV camcorder was connected via HDMI to a
ms2130 usb3 capture card.<br>
<br>
My procedure description here on openSUSE Tumbleweed-Slowroll,
kernel 6.12.30-1.0.4.sr20250501-longterm<br>

1) Settings > Preferences > Record<br>
<ul>
<li>File format: FFMPEG mp4</li>
</ul>
Video In: <br>
<ul>
<li>Record driver: Video4Linux2 /dev(video0</li>
</ul>
The first thing I noticed was that default Record video setting was
SD NTSC, not PAL as else according to my time zone.<br>
Could this possibly be changed as else?<br>
<ul>
<li>Frames to record on disk: 30 (default)?</li>
</ul>
Changed frame to a camcorder resolution and fps supported by v4l2
and ms2130:<br>
<ul>
<li>Frame: 1920 x 1080 (was default NTSC SD)</li>
<li>fps: 50 (progressive)</li>
</ul>
<br>
File > Record r<br>
<br>
Two windows opened, one showing the running record time etc. and the
other the camera window image.<br>
<br>
<br>
My simple question are:<br>
<ol>
<li>Should the video stream be "recorded" and stored somewhere
(according to some settings)?</li>
<li>Can it be saved as a video file type on disk?</li>
</ol>
I am also interested to see if yuv422p color sampling is retained.<br>
