Apply an MPlayer filter to the input video.
This filter provides a wrapper around most of the filters of
MPlayer/MEncoder.
This wrapper is considered experimental. Some of the wrapped filters
may not work properly and we may drop support for them, as they will
be implemented natively into FFmpeg. Thus you should avoid
depending on them when writing portable scripts.
The filters accepts the parameters:
@var{filter_name}[:=]@var{filter_params}
@var{filter_name} is the name of a supported MPlayer filter,
@var{filter_params} is a string containing the parameters accepted by
the named filter.
The list of the currently supported filters follows:
@table @var
@item 2xsai
@item blackframe
@item boxblur
@item cropdetect
@item decimate
@item delogo

The parameter syntax and behavior for the listed filters are the same
of the corresponding MPlayer filters. For detailed instructions check
the "VIDEO FILTERS" section in the MPlayer manual.
Some examples follow:
@example
# remove a logo by interpolating the surrounding pixels
mp=delogo=200:200:80:20:1
# adjust gamma, brightness, contrast
mp=eq2=1.0:2:0.5
# tweak hue and saturation
mp=hue=100:-10
@end example
