cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_VideoDownSample420(mlib_u8 *dst, const mlib_u8 *src0, const mlib_u8 *src1, mlib_s32 n); DESCRIPTION
The mlib_VideoDownSample420() function performs down sampling rate conversion used in JPEG File Interchange Format (JFIF). PARAMETERS
The function takes the following arguments: dst Pointer to destination row. dst must be 8-byte aligned. src0 Pointer to upper source row. src0 must be 8-byte aligned. src1 Pointer to middle source row. src1 must be 8-byte aligned. n Length of source rows. n must be greater than 1. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
