1.18.1 is much too old.

If you want reliable output from v4l2-compliance, then always compile from the
git repository (git://linuxtv.org/v4l-utils.git).

The version distributed by distros is much too infrequently updated, and shouldn't
be used.

If you still have issues with the version from the git repo, then let me know!
