mediaLib Library Functions      mlib_VideoColorYUV2ARGB422(3MLIB)



NAME
     mlib_VideoColorYUV2ARGB422 - YUV to RGB color conversion

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     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);


DESCRIPTION
     The mlib_VideoColorYUV2ARGB422() function  performs  YUV  to
     RGB  color conversion used in MPEG1 and MPEG2 video compres-
     sion in the 4:2:2 sequence.


     The luminance component is stored in Y, the chrominance com-
     ponents 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.

PARAMETERS
     The function takes the following arguments:

     argb          Pointer to the destination packed ARGB image.


     y             Pointer to the source Y component.


     u             Pointer to the source U component.


     v             Pointer to the source V component.


     width         Width of the image.


     height        Height of the image.


     rgb_stride    Stride, in bytes, between adjacent rows in the
                   destination image.


     y_stride      Stride, in bytes, between adjacent rows in the
                   Y component image.

     uv_stride     Stride, in bytes, between adjacent rows in the
                   U and V component images.


RETURN VALUES
     The function returns MLIB_SUCCESS if  successful.  Otherwise
     it returns MLIB_FAILURE.
