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>
<br>
~/Applications> ./CinGG-20250430-x86_64.AppImage<br>

<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>
Unhappily, when I reconnected the camcorder to re-test today, the
second window with the camera image did not longer open!!<br>
I've tried to reset the machine and camcorder, but no. Did also a
test with system ffplay (when the v4l2 was free again) and it
worked.<br>
<br>
Obviously here is something that causes this confusing issue, but
what? load straty, a changed setting or something else?<br>
Happily the window opened yesterday, so I know the should work. <br>
I understand this can be difficult to troubleshoot without a similar
setup.<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>

3. Additional, after further reading more in the manual section
(before EasyCap):<br>
Transfer VHS/DVD Media or Video8/Hi8 Tapes into CINELERRA-GG<br>
<a class="moz-txt-link-freetext" href="https://cinelerra-gg.org/download/CinelerraGG_Manual/Transfer_VHS_DVD_Media_or_V.html">https://cinelerra-gg.org/download/CinelerraGG_Manual/Transfer_VHS_DVD_Media_or_V.html</a><br>
<br>
Fig 13.17 vs text section:<br>
<ul>
<li>In the Video In section, change the Record Driver to whatever
makes sense for your capture card. The test case for the CX23418
would use Video4Linux2 MPEG. </li>
<li>A test case for an EasyCap Model #DC60 would use Video4Linux2
JPEG. If unknown what your card uses, you should experiment with
Video4Linux2 or Screencapture as good possibilities.</li>
</ul>
Is there a typo in the text line, so that it rather should be: The
test case for the CX23418 would use "DVB" .......(as in Fig 13.17)?<br>
<br>
<br>
4, Fig 13.18 and text section below<br>
<a class="moz-txt-link-freetext" href="https://cinelerra-gg.org/download/CinelerraGG_Manual/Transfer_VHS_DVD_Media_or_V.html#fig:vhs01">https://cinelerra-gg.org/download/CinelerraGG_Manual/Transfer_VHS_DVD_Media_or_V.html#fig:vhs01</a><br>
<ul>
<li>Click on the Antenna icon (<span class="MATH">3<sup>rd</sup></span>
icon from the left on the left side of the right hand screen
window).
</li>
<li>In the popup <span class="textit">Channels</span> menu, click
on <span class="texttt">Add</span> which brings up the <span
class="textit">Edit Channel</span> menu.
</li>
</ul>
<p>Obviously I cannot see the lower part of Fig 13.18 before the
Camera window appear again?</p>
