I tried to Record camcorder video stream via v4l2 and hdmi-usb3
capture as input device.
ms2130 is more powerful but else similar to the usb2 EasyCap device
example described in the CinGG manual
https://cinelerra-gg.org/download/CinelerraGG_Manual/Use_Case_1_a_EasyCap.html
My Sony FX7-E 1080i50 HDV camcorder was connected via HDMI to a ms2130
usb3 capture card.
My procedure description here on openSUSE Tumbleweed-Slowroll, kernel
6.12.30-1.0.4.sr20250501-longterm
~/Applications> ./CinGG-20250430-x86_64.AppImage

1) Settings > Preferences > Record
* File format: FFMPEG mp4
Video In:
* Record driver: Video4Linux2 /dev(video0
The first thing I noticed was that default Record video setting was SD
NTSC, not PAL as else according to my time zone.
Could this possibly be changed as else?
* Frames to record on disk: 30 (default)?
Changed frame to a camcorder resolution and fps supported by v4l2 and
ms2130:
* Frame: 1920 x 1080 (was default NTSC SD)
* fps: 50 (progressive)
File > Record r
Two windows opened, one showing the running record time etc. and the
other the camera window image.
Unhappily, when I reconnected the camcorder to re-test today, the second
window with the camera image did not longer open!!
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.
Obviously here is something that causes this confusing issue, but what?
load straty, a changed setting or something else?
Happily the window opened yesterday, so I know the should work.
I understand this can be difficult to troubleshoot without a similar setup.
My simple question are:
1. Should the video stream be "recorded" and stored somewhere
(according to some settings)?
2. Can it be saved as a video file type on disk?
I am also interested to see if yuv422p color sampling is retained.
3. Additional, after further reading more in the manual section (before
EasyCap):
Transfer VHS/DVD Media or Video8/Hi8 Tapes into CINELERRA-GG
https://cinelerra-gg.org/download/CinelerraGG_Manual/Transfer_VHS_DVD_Media_or_V.html
Fig 13.17 vs text section:
* 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.
* 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.
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)?
4, Fig 13.18 and text section below
https://cinelerra-gg.org/download/CinelerraGG_Manual/Transfer_VHS_DVD_Media_or_V.html#fig:vhs01
* Click on the Antenna icon (3^rd icon from the left on the left side
of the right hand screen window).
* In the popup Channels menu, click on Add which brings up the Edit
Channel menu.
Obviously I cannot see the lower part of Fig 13.18 before the Camera
window appear again?
