Deinterlace the input video ("yadif" means "yet another deinterlacing
filter").
The filter accepts parameters as a list of @var{key}=@var{value}
pairs, separated by ":". If the key of the first options is omitted,
the arguments are interpreted according to syntax
@var{mode}:@var{parity}:@var{deint}.
This filter accepts the following options:
The description of the accepted parameters follows.
@table @option
@item mode
Specify the interlacing mode to adopt. Accept one of the following
values:
