@end example
@section transpose_npp
Transpose rows with columns in the input video and optionally flip it.
For more in depth examples see the @ref{transpose} video filter, which shares mostly the same options.
It accepts the following parameters:
@table @option
@item dir
Specify the transposition direction.
Can assume the following values:
@table @samp
@item cclock_flip
Rotate by 90 degrees counterclockwise and vertically flip. (default)
@item clock
Rotate by 90 degrees clockwise.
@item cclock
Rotate by 90 degrees counterclockwise.
@item clock_flip
Rotate by 90 degrees clockwise and vertically flip.
@end table
@item passthrough
Do not apply the transposition if the input geometry matches the one
specified by the specified value. It accepts the following values:
@table @samp
@item none
Always apply transposition. (default)
@item portrait
Preserve portrait geometry (when @var{height} >= @var{width}).
@item landscape
Preserve landscape geometry (when @var{width} >= @var{height}).
@end table
@end table
@section trim
Trim the input so that the output contains one continuous subpart of the input.
