Hi：

Thank you for your suggestion, there are no dmesg alarms.

When I execute the following command, a blackboard appears. Please help me find out why?

v4l2-ctl -d /dev/video0 --stream-mmap --stream-to-host 192.168.1.111

Looks like v4l2-ctl able capture succesfully but the framerate is lower.
Please check below command able show correct framerate.
If yes the I can tell the camera working well, the problem could be in V4L2Viewer.

v4l2-ctl -d /dev/video0 --stream-mmap

Every thing looks good. I suspect the V4L2Viewer have problem to support it.
You can try “gst-launch-1.0 v4l2src …”

gst-launch-1.0 v4l2src ! 'video/x-raw, format=(string)UYVY, width=(int)1920, height=(int)1080, framerate=(fraction)25/1' ! xvimagesink -ev

wxsrite · March 8, 2024, 11:05am

Hi：
The problem still exists.

gst-launch-1.0 -ev v4l2src device=/dev/video1 ! rawvideoparse format=4 width=1920 height=1080 ! videoconvert ! videoflip method=rotate-180 ! fpsdisplaysink video-sink=xvimagesink sync=false

I don’t see any failed for the NVCSI/VI capture from the sensor.
Maybe dump the frame by check by tools.

v4l2-ctl --set-fmt-video=width=1920,height=1080 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=5 --stream-to=test.raw -d /dev/video0

wxsrite · March 11, 2024, 1:49am

What tools to use? Is there any way to deal with it?

7-yuv should able to check it.

The output data looks like incorrect. Suppose it could be the sensor setting cause the problem.
You may configure sensor output test pattern to confirm it.
