Adapt veye-Mipi-IMX462 on Xavier NX. On 4K display screen, when using the following command to open the camera, the video output is normal, but when moving the mouse, the screen turns to red interface and there is no video output. What is the reason?
Note: Video output is tested on other 2K displays.
gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! “video/x-raw(memory:NVMM),format=(string)UYVY, width=(int)1920, height=(int)1080” ! nvvidconv ! “video/x-raw(memory:NVMM),format=(string)I420” ! nvoverlaysink sync=false

Please use xvimagesink instead of nvoverlaysink to confirm.
Yes, when I use the following command, the video will output normally.
gst-launch-1.0 -e v4l2src io-mode=4 device=/dev/video0 do-timestamp=true ! ‘video/x-raw, width=1920, height=1080, framerate=30/1, format=UYVY’ ! xvimagesink sync=false
It could be the display control underflow cause the problem.
Suggest using xvimagesink instead.
