mlib_VideoColorYUV420seq_to_UYVY422int - convert YUV sequential to interleaved SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> void mlib_VideoColorYUV420seq_to_UYVY422int(mlib_u32 *UYVY, const mlib_u8 *Y,const mlib_u8 *U, const mlib_u8 *V, mlib_s32 w, mlib_s32 h, mlib_s32 dlb, mlib_s32 ylb, mlib_s32 uvlb); DESCRIPTION
The Y, U, V pixel streams are combined into a UYVY pixel stream. All pixel components are 8-bit unsigned integers. The Y buffer has dimen- sions w and h. The U and V buffers have dimensions w/2 and h/2. Dimensions w and h are assumed to be even. Successive rows of the output buffer UYVY use successive rows of Y and the same rows of U and V. The following equation is used: UYVY[r][c/2] = (U[r/2][c/2] << 24) | (Y[r][c] << 16) | (V[r/2][c/2] << 8) | (Y[r][c+1]) UYVY[r+1][c/2] = (U[r/2][c/2] << 24) | (Y[r+1][c] << 16) | (V[r/2][c/2] << 8) | (Y[r+1][c+1]) where r = 0, 2, 4, ..., h-2; and c = 0, 2, 4, ..., w-2. PARAMETERS
The function takes the following arguments: UYVY Pointer to output buffer. Y Pointer to Y input buffer. U Pointer to U input buffer. V Pointer to V input buffer. w Image width in pixels. h Image height in lines. dlb Linebytes for UYVY buffer. ylb Linebytes for Y buffer. uvlb Linebytes for U and V buffers. RETURN VALUES
None. ATTRIBUTES
