Set the rotation the video is assumed to be encoded with in degrees.
The special value ``-1`` uses the input format.
``<dw>``, ``<dh>``

the video is scaled in both directions instead of just changing the
aspect ratio is an implementation detail, and might change later.
``noformat[=fmt]``
Restricts the color space for the next filter without doing any conversion.
