1 @chapter Scaler Options
2 @c man begin SCALER OPTIONS
4 The video scaler supports the following named options.
6 Options may be set by specifying -@var{option} @var{value} in the
7 FFmpeg tools. For programmatic use, they can be set explicitly in the
8 @code{SwsContext} options or through the @file{libavutil/opt.h} API.
13 Set the scaler flags. This is also used to set the scaling
14 algorithm. Only a single algorithm should be selected.
16 It accepts the following values:
19 Select fast bilinear scaling algorithm.
22 Select bilinear scaling algorithm.
25 Select bicubic scaling algorithm.
28 Select experimental scaling algorithm.
31 Select nearest neighbor rescaling algorithm.
34 Select averaging area rescaling algorithm.
37 Select bicubic scaling algorithm for the luma component, bilinear for
41 Select Gaussian rescaling algorithm.
44 Select sinc rescaling algorithm.
47 Select lanczos rescaling algorithm.
50 Select natural bicubic spline rescaling algorithm.
53 Enable printing/debug logging.
56 Enable accurate rounding.
59 Enable full chroma interpolation.
62 Select full chroma input.
65 Enable bitexact output.
75 Set destination width.
78 Set destination height.
81 Set source pixel format (must be expressed as an integer).
84 Set destination pixel format (must be expressed as an integer).
90 Select destination range.
93 Set scaling algorithm parameters. The specified values are specific of
94 some scaling algorithms and ignored by others. The specified values
95 are floating point number values.
