@item sws_param
Specify the optional parameters to be used for the scale filter which
is automatically inserted when an input change is detected in the
input size or format.
This option is deprecated and ignored. Prepend @code{sws_flags=@var{flags};}
to the filtergraph description to specify swscale flags for automatically
