@ -6531,6 +6531,19 @@ Set the EBU scale meter. Default is @code{9}. Common values are @code{9} and
@code{18}, respectively for EBU scale meter +9 and EBU scale meter +18. Any
other integer value between this range is allowed.
@item framelog
Force the frame logging level.
Available values are:
@table @samp
@item info
information logging level
@item verbose
verbose logging level
@end table
By default, the logging level is set to @var{info}. If the @option{video}
option is set, it switches to @var{verbose}.
@end table
