@section fillborders
|
||||
|
||||
Fill borders of the input video, without changing video stream dimensions.
|
||||
Sometimes video can have garbage at the four edges and you may not want to
|
||||
crop video input to keep size multiple of some number.
|
||||
|
||||
This filter accepts the following options:
|
||||
|
||||
@table @option
|
||||
@item left
|
||||
Number of pixels to fill from left border.
|
||||
|
||||
@item right
|
||||
Number of pixels to fill from right border.
|
||||
|
||||
@item top
|
||||
Number of pixels to fill from top border.
|
||||
|
||||
@item bottom
|
||||
Number of pixels to fill from bottom border.
|
||||
|
||||
@item mode
|
||||
Set fill mode.
|
||||
|
||||
It accepts the following values:
|
||||
@table @samp
|
||||
@item smear
|
||||
fill pixels using outermost pixels
|

|

@item mirror
|

fill pixels using mirroring
|

@item fixed
|

@end table

Default is @var{smear}.
|

@item color
|
