You'll likely need to add your user account to the 'video' group

  $ sudo usermod -aG video $USER
  $ newgrp video

The newgrp command adds the group to your current session, but you'll
probably just want to log out and back in again completely to make sure
it takes effect.

Hope this helps, do let us know what you're integrating libcamera into -
it's interesting to know where the library gets used.
