Typedef Documentation

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

Definition at line 63 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:
c SWS scaling context
chrFilter vertical chroma scaling coefficients, 12bit [0,4096]
chrUSrc scaled chroma (U) source data, 15bit for 8-10bit output, 19-bit for 16bit output (in int32_t)
chrVSrc scaled chroma (V) source data, 15bit for 8-10bit output, 19-bit for 16bit output (in int32_t)
chrFilterSize number of vertical chroma input lines to scale
dest pointer to the output plane. For >8bit output, this is in uint16_t
dstW width of chroma planes

Definition at line 114 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:
c SWS scaling context
lumSrc scaled luma (Y) source data, 15bit for 8-10bit output, 19-bit for 16bit output (in int32_t)
chrUSrc scaled chroma (U) source data, 15bit for 8-10bit output, 19-bit for 16bit output (in int32_t)
chrVSrc scaled chroma (V) source data, 15bit for 8-10bit output, 19-bit for 16bit output (in int32_t)
alpSrc scaled alpha (A) source data, 15bit for 8-10bit output, 19-bit for 16bit output (in int32_t)
dest pointer to the output plane. For 16bit output, this is uint16_t
dstW width of lumSrc and alpSrc in pixels, number of pixels to write into dest[]
uvalpha chroma 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)
y vertical 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 150 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:
c SWS scaling context
lumSrc scaled luma (Y) source data, 15bit for 8-10bit output, 19-bit for 16bit output (in int32_t)
chrUSrc scaled chroma (U) source data, 15bit for 8-10bit output, 19-bit for 16bit output (in int32_t)
chrVSrc scaled chroma (V) source data, 15bit for 8-10bit output, 19-bit for 16bit output (in int32_t)
alpSrc scaled alpha (A) source data, 15bit for 8-10bit output, 19-bit for 16bit output (in int32_t)
dest pointer to the output plane. For 16bit output, this is uint16_t
dstW width of lumSrc and alpSrc in pixels, number of pixels to write into dest[]
yalpha luma/alpha scaling coefficients for the second input line. The first line's coefficients can be calculated by using 4096 - yalpha
uvalpha chroma scaling coefficient for the second input line. The first line's coefficients can be calculated by using 4096 - uvalpha
y vertical 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.

dest pointer to the output plane. For >8bit output, this is in uint16_t
dstW width of destination in pixels
dither ordered dither array of type int16_t and size 8
offset Dither offset

typedef void(* yuv2planarX_fn)(const int16_t *filter, int filterSize, const int16_t **src, uint8_t *dest, int dstW, const uint8_t *dither, int offset)

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

Parameters:
filter vertical luma/alpha scaling coefficients, 12bit [0,4096]
src scaled luma (Y) or alpha (A) source data, 15bit for 8-10bit output, 19-bit for 16bit output (in int32_t)
filterSize number of vertical input lines to scale
dest pointer to output plane. For >8bit output, this is in uint16_t
dstW width of destination pixels
offset Dither offset
