Specify when to evaluate @var{width} and @var{height} expression. It accepts the following values:

@item frame
Evaluate expressions for each incoming frame.

@section scale2ref_npp
Use the NVIDIA Performance Primitives (libnpp) to scale (resize) the input
video, based on a reference video.
See the @ref{scale_npp} filter for available options, scale2ref_npp supports the same
but uses the reference video instead of the main input as basis. scale2ref_npp
also supports the following additional constants for the @option{w} and
@option{h} options:
@table @var
@item main_w
@item main_h
The main input video's width and height
@item main_a
The same as @var{main_w} / @var{main_h}
@item main_sar
The main input video's sample aspect ratio
@item main_dar, mdar
The main input video's display aspect ratio. Calculated from
@code{(main_w / main_h) * main_sar}.
@item main_n
The (sequential) number of the main input frame, starting from 0.
Only available with @code{eval=frame}.
@item main_t
The presentation timestamp of the main input frame, expressed as a number of
seconds. Only available with @code{eval=frame}.
@item main_pos
The position (byte offset) of the frame in the main input stream, or NaN if
this information is unavailable and/or meaningless (for example in case of synthetic video).

Scale a subtitle stream (b) to match the main video (a) in size before overlaying
@example

@item
Scale a logo to 1/10th the height of a video, while preserving its display aspect ratio.
@example
[logo-in][video-in]scale2ref_npp=w=oh*mdar:h=ih/10[logo-out][video-out]
