29 Indent Options

The video supports some of the following options.

Options can be used in the FFmpeg tool set-option valueFormat, or in thearesampleIn the filter tooption=valueForm settings, or you can use thelibavutil/opt.hThe API or explicitly set theSwrContextoption.

• Sws_flags

  Sets the indent flag. Also used to set the scaling algorithm, only one algorithm can be selected.

  Accept the following values:

  • ' Fast_bilinear '

    Fast bilinear scaling algorithm

  • ' Bilinear '

    Bilinear scaling algorithm

  • ' Bicubic '

    A three-time scaling algorithm.

  • ' Experimental '

    Experimental scaling algorithm.

  • ' Neighbor '

    Nearest Neighbor sampling scaling algorithm

  • ' Area '

    Average regional scale scaling algorithm.

  • ' Bicublin '

    The dual-linear scaling algorithm is adopted for the luminance using a double three-time scaling algorithm.

  • ' Gauss '

    Gaussian scaling algorithm

  • ' Sinc '

    Singh Scaling algorithm

  • ' Lanczos '

    Lanczos chunking Scaling algorithm

  • ' Spline '

    Spline interpolation scaling algorithm with natural double three times

  • ' Print_info '

    Allow output/debug logs

  • ' Accurate_rnd '

    Allow Precision rounding

  • ' Full_chroma_int '

    Allows for full chroma interpolation

  • ' Full_chroma_inp '

    Select the full concentration input

  • ' Bitexact '

    Allow Bitexact (bit-accurate algorithm) output

• Srcw

  Set Source width

• Srch

  Set source Height

• Dstw

  Set the target width

• Dsth

  Set Target height

• Src_format

  Sets the source pixel format (must be represented as an integer).

• Dst_format

  Sets the destination pixel format (must be represented as an integer).

• Src_range

  Select Source Area Range

• Dst_range

  Select target Area Range

• Param0, param1

  Sets the scaling algorithm parameters. The specified value is applicable to a particular scaling algorithm and may be ignored by other algorithms. Value is floating point number

• Sws_dither

  Sets the jitter algorithm. Receive the following value, default to ' auto '.

  • ' Auto '

    Automatic selection

  • ' None '

    No jitter

  • ' Bayer '

    Bayer Jitter

  • ' Ed '

    Error diffusion (Error diffusion) jitter

  • ' A_dither '

    Arithmetic (arithmetic) jitter, based on addition

  • ' X_dither '

    Arithmetic (arithmetic) jitter, based on XOR, (XOR) ( a_dither more randomness/less patterning).
