Hi,

I read all the manuals in 'doc' folder and found that Intel Media SDK supports planar YUV format( ex.NV12 ) but not packed YUV format( ex. YUYV ).

Therefore I use the converter function as below whosefirst parameter is YUYV format and the Second is NV12.

Ioptimizedthe functionin my own way but it needs many CPU operation in line 17-30. In multi-decoder environment, it's terrible.

Has Intel any plan to support YUYV format? ... as decoder output.
Or give me any information abouthow todiscard many pixel-by-pixel copys( shown in line 17-30 ).

WriteFrame( BYTE *pDec, mfxFrameSurface1 *pSurface )
{
	if ( !pSurface || !pSurface->Data.Y || !pSurface->Data.UV )
		return FALSE;

	BYTE *Y		= pSurface->Data.Y;
	BYTE *UV	= pSurface->Data.UV;
	int i, j, k, h, w, w_pitch, h_Y, h_UV;
	h = pSurface->Info.CropH;
	w = pSurface->Info.CropW;	
	w_pitch = pSurface->Data.Pitch;		
	i = h;
	k = w * h * 2 - 1;
	h_Y = (h - 1) * w_pitch;
	h_UV = ( (h - 1) >> 1 ) * w_pitch;

	while ( i-- )
	{
		j = w;
		while ( j-- )
		{	
			pDec[ k-- ] = UV[ h_UV + j ];
			pDec[ k-- ] = Y[ h_Y + j-- ];
			pDec[ k-- ] = UV[ h_UV + j ];
			pDec[ k-- ] = Y[ h_Y + j ];
		}
		h_Y -= w_pitch;
		if ( i & 0x1 )
			h_UV -= w_pitch;
	}

	return TRUE;
}
