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
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.
My simple question are:
- Should the video stream be "recorded" and stored somewhere
(according to some settings)?
- Can it be saved as a video file type on disk?
I am also interested to see if yuv422p color sampling is retained.
A copy from the running terminal:
