Here we are removing duplicates rows based on 2 criteria i.e
1)we check for 2,3,4,5 columns if they are same if so then remove one of the duplicate row.
2)Retain the row which has its largest value in column 19 & which has large set of columns with values in that row.
Help me out if any one has an idea also..i am trying this out from past one week...

Thanks in advance..SmilieSmilie

mlib_VideoColorYUV444seq_to_ARGBint(3MLIB)		    mediaLib Library Functions			mlib_VideoColorYUV444seq_to_ARGBint(3MLIB)

NAME

       mlib_VideoColorYUV444seq_to_ARGBint - color convert YUV sequential to ARGB interleaved

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       void  mlib_VideoColorYUV444seq_to_ARGBint(mlib_u32  *ARGB,  const  mlib_u8  *Y, const mlib_u8 *U, const mlib_u8 *V, const mlib_u8 *A_array,
       mlib_u8 A_const, mlib_s32 w, mlib_s32 h, mlib_s32 dlb, mlib_s32 slb);

DESCRIPTION

       The Y, U, V pixel streams are converted into an ARGB pixel stream.  All pixel components are 8-bit  unsigned  integers.	All  buffers  have
       dimensions w and h.

       The alpha values for this function work in the following fashion:

	 o  If A_array pointer is not NULL, the values are taken from there. It has to have the same dimensions as the Y buffer.

	 o  If A_array pointer is NULL, the alpha values for every pixel are set to A_const.

       The following equation is used:

       |R|   |1.1644  0.0000  1.5966|	[|Y|   | 16.0000|]
       |G| = |1.1644 -0.3920 -0.8132| * [|U| - |128.0000|]
       |B|   |1.1644  2.0184  0.0000|	[|V|   |128.0000|]

PARAMETERS

       The function takes the following arguments:

       ARGB	       Pointer to output buffer.

       Y	       Pointer to Y input buffer.

       U	       Pointer to U input buffer.

       V	       Pointer to V input buffer.

       A_array	       Array of alpha values.

       A_const	       Constant alpha value.

       w	       Image width in pixels.

       h	       Image height in lines.

       dlb	       Linebytes for output buffer.

       slb	       Linebytes for input buffers.

RETURN VALUES

       None.
