FFMPEG-SCALER(1)					      FFMPEG-SCALER(1)

NAME
       ffmpeg-scaler - FFmpeg video scaling and pixel format converter

DESCRIPTION
       The FFmpeg rescaler provides an high-level interface to the libswscale
       library image conversion utilities. In particular it allows to perform
       image rescaling and pixel format conversion.

SCALER OPTIONS
       The video scaler supports the following named options.

       Options may be set by specifying -option value in the FFmpeg tools. For
       programmatic use, they can be set explicitly in the "SwsContext"
       options or through the libavutil/opt.h API.

       sws_flags
	   Set the scaler flags. This is also used to set the scaling
	   algorithm. Only a single algorithm should be selected.

	   It accepts the following values:

	   fast_bilinear
	       Select fast bilinear scaling algorithm.

	   bilinear
	       Select bilinear scaling algorithm.

	   bicubic
	       Select bicubic scaling algorithm.

	   experimental
	       Select experimental scaling algorithm.

	   neighbor
	       Select nearest neighbor rescaling algorithm.

	   area
	       Select averaging area rescaling algorithm.

	   bicubiclin
	       Select bicubic scaling algorithm for the luma component,
	       bilinear for chroma components.

	   gauss
	       Select Gaussian rescaling algorithm.

	   sinc
	       Select sinc rescaling algorithm.

	   lanczos
	       Select lanczos rescaling algorithm.

	   spline
	       Select natural bicubic spline rescaling algorithm.

	   print_info
	       Enable printing/debug logging.

	   accurate_rnd
	       Enable accurate rounding.

	   full_chroma_int
	       Enable full chroma interpolation.

	   full_chroma_inp
	       Select full chroma input.

	   bitexact
	       Enable bitexact output.

       srcw
	   Set source width.

       srch
	   Set source height.

       dstw
	   Set destination width.

       dsth
	   Set destination height.

       src_format
	   Set source pixel format (must be expressed as an integer).

       dst_format
	   Set destination pixel format (must be expressed as an integer).

       src_range
	   Select source range.

       dst_range
	   Select destination range.

       param0, param1
	   Set scaling algorithm parameters. The specified values are specific
	   of some scaling algorithms and ignored by others. The specified
	   values are floating point number values.
