For example, no header was found for a format which depends on headers or an illegal combination of parameters is used. * ``16`` (``error``): Something went wrong and cannot losslessly be recovered. However, not all future data is affected. * ``24`` (``warning``): Something somehow does not look correct. This may or may not lead to problems. * ``32`` (``info``): Standard information. * ``40`` (``verbose``): Detailed information. * ``48`` (``debug``): Stuff which is only useful for libav* developers. * ``56`` (``trace``): Extremely verbose debugging, useful for libav* development.
