Parameters
cSWS scaling context
lumSrcscaled luma (Y) source data, 15bit for 8-10bit output, 19-bit for 16bit output (in int32_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)
