NAME
mlib_VideoColorUYV444int_to_YUYV422int - convert UYV interleaved with subsampling SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> void mlib_VideoColorUYV444int_to_YUYV422int(mlib_u32 *YUYV, const mlib_u8 *UYV, mlib_s32 w, mlib_s32 h, mlib_s32 dlb, mlib_s32 slb); DESCRIPTION
The UYV pixel stream is broken apart and recombined into a YUYV pixel stream. All pixel components are 8-bit unsigned integers. The UYV buffer has dimensions w and h. Dimension w is assumed to be a multiple of 2. Adjacent U and V values are averaged to get the output U and V values. The sequence of values in the input stream is U[r][c], Y[r][c], V[r][c], U[r][c+1], Y[r][c+1], V[r][c+1], ... The following equation is used: YUYV[r][c/2] = (Y[r][c] << 24) | (((U[r][c] + U[r][c+1]) / 2) << 16) | (Y[r][c+1] << 8) | (((V[r][c] + V[r][c+1]) / 2)) where r = 0, 1, 2, ..., h-1; and c = 0, 2, 4, ..., w-2. PARAMETERS
The function takes the following arguments: YUYV Pointer to output buffer. UYV Pointer to input buffer. w Image width in pixels. h Image height in lines. dlb Linebytes for output buffer. slb Linebytes for input buffer. RETURN VALUES
None. ATTRIBUTES
