Hi @bobding
Can you execute v4l2-ctl --list-formats-ext and send the result to me?
You can also use the following methods to test the camera:

  1. Try to use vlc to access the camera.
  2. Use this command to test the camera: v4l2-ctl --set-fmt-video=width=5120,height=800 --stream-mmap --stream-count=-1

Here are results

v4l2-ctl --list-formats-ext

Thank you for the information,

It looks like everything is normal with the camera.

Maybe not to set the resolution and format information?

Can you try not to add the -f parameter? From the above information, the camera is working normally. Perhaps this is an application problem.
