cc [ flag... ] file... –lmlib [ library... ] #include <mlib.h> mlib_status mlib_VideoColorYUV2ARGB422(mlib_u8 *argb, const mlib_u8 *y, const mlib_u8 *u, const mlib_u8 *v, mlib_s32 width, mlib_s32 height, mlib_s32 rgb_stride, mlib_s32 y_stride, mlib_s32 uv_stride);
The mlib_VideoColorYUV2ARGB422() function performs YUV to RGB color conversion used in MPEG1 and MPEG2 video compression in the 4:2:2 sequence.
The luminance component is stored in Y, the chrominance components are stored in U and V, respectively. The size of the chrominance image depends on the chroma format used by the sequence. In this sequence, the chrominance components are subsampled 2-to-1 in only the horizontal direction in respect to the luminance component.
The function takes the following arguments:
Pointer to the destination packed ARGB image.
Pointer to the source Y component.
Pointer to the source U component.
Pointer to the source V component.
Width of the image.
Height of the image.
Stride, in bytes, between adjacent rows in the destination image.
Stride, in bytes, between adjacent rows in the Y component image.
Stride, in bytes, between adjacent rows in the U and V component images.
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
