Typedef Documentation

typedef struct SwsContext SwsContext
typedef int(* SwsFunc)(struct SwsContext *context, const uint8_t *src[], int srcStride[], int srcSliceY, int srcSliceH, uint8_t *dst[], int dstStride[])

Definition at line 61 of file swscale_internal.h.

typedef void(* yuv2interleavedX_fn)(struct SwsContext *c, const int16_t *chrFilter, int chrFilterSize, const int16_t **chrUSrc, const int16_t **chrVSrc, uint8_t *dest, int dstW)

Write one line of horizontally scaled chroma to interleaved output with multi-point vertical scaling between input pixels.

Parameters
cSWS scaling context
chrFiltervertical chroma scaling coefficients, 12bit [0,4096]
chrUSrcscaled chroma (U) source data, 15bit for 8-10bit output, 19-bit for 16bit output (in int32_t)
chrVSrcscaled chroma (V) source data, 15bit for 8-10bit output, 19-bit for 16bit output (in int32_t)
chrFilterSizenumber of vertical chroma input lines to scale
destpointer to the output plane. For >8bit output, this is in uint16_t
dstWwidth of chroma planes

Definition at line 112 of file swscale_internal.h.

typedef void(* yuv2packed1_fn)(struct SwsContext *c, const int16_t *lumSrc, const int16_t *chrUSrc[2], const int16_t *chrVSrc[2], const int16_t *alpSrc, uint8_t *dest, int dstW, int uvalpha, int y)

Write one line of horizontally scaled Y/U/V/A to packed-pixel YUV/RGB output without any additional vertical scaling (or point-scaling).

Note that this function may do chroma scaling, see the "uvalpha" argument.

Parameters
cSWS scaling context
lumSrcscaled luma (Y) source data, 15bit for 8-10bit output, 19-bit for 16bit output (in int32_t)
chrUSrcscaled chroma (U) source data, 15bit for 8-10bit output, 19-bit for 16bit output (in int32_t)
chrVSrcscaled chroma (V) source data, 15bit for 8-10bit output, 19-bit for 16bit output (in int32_t)
alpSrcscaled alpha (A) source data, 15bit for 8-10bit output, 19-bit for 16bit output (in int32_t)
destpointer to the output plane. For 16bit output, this is uint16_t
dstWwidth of lumSrc and alpSrc in pixels, number of pixels to write into dest[]
uvalphachroma scaling coefficient for the second line of chroma pixels, either 2048 or 0. If 0, one chroma input is used for 2 output pixels (or if the SWS_FLAG_FULL_CHR_INT flag is set, it generates 1 output pixel). If 2048, two chroma input pixels should be averaged for 2 output pixels (this only happens if SWS_FLAG_FULL_CHR_INT is not set)
yvertical line number for this output. This does not need to be used to calculate the offset in the destination, but can be used to generate comfort noise using dithering for some output formats.

Definition at line 148 of file swscale_internal.h.

typedef void(* yuv2packed2_fn)(struct SwsContext *c, const int16_t *lumSrc[2], const int16_t *chrUSrc[2], const int16_t *chrVSrc[2], const int16_t *alpSrc[2], uint8_t *dest, int dstW, int yalpha, int uvalpha, int y)

Write one line of horizontally scaled Y/U/V/A to packed-pixel YUV/RGB output by doing bilinear scaling between two input lines.

Parameters

destpointer to the output plane. For 16bit output, this is uint16_t
dstWwidth of lumSrc and alpSrc in pixels, number of pixels to write into dest[]
yalphaluma/alpha scaling coefficients for the second input line. The first line's coefficients can be calculated by using 4096 - yalpha
uvalphachroma scaling coefficient for the second input line. The first line's coefficients can be calculated by using 4096 - uvalpha
yvertical line number for this output. This does not need to be used to calculate the offset in the destination, but can be used to generate comfort noise using dithering for some output formats.
