TDA2EVM5777: Displaying Input And Output Image on the Screen Simultaneously

May be, RGBtoGrey just making same input chroma buffer to 0x80. Could you please check the code of this alg plugin?

Hello Birjesh,

I Used Dup link so if irgbtogray algorithm changes input image then also I will get original Input Image on display As I duplicated input Image

Vipul,

Dup link just duplicates the pointers, does not duplicate buffer contents, so it will still be same buffer..

Rgds,

Yes Birjesh,

So I found that, in Algorithm input image is modified 

Int32 Alg_ColorToGrayProcess(Alg_ColorToGray_Obj *algHandle,
UInt32 *inPtr[],
UInt32 width,
UInt32 height,
UInt32 inPitch[],
UInt32 dataFormat
)
{
Int32 rowIdx;
Int32 colIdx;

UInt32 wordWidth;
UInt32 *outPtr;
UInt32 count

outPtr = (UInt32 *)malloc(sizeof(UInt32)*width*height*2);

UInt32 *inputPtr;
UInt32 mask = 0x00FF00FF;
UInt32 mask1 = 0x80008000;

if(dataFormat == SYSTEM_DF_YUV422I_YUYV)
{
wordWidth = (width*2)>>2;
}
else
{
return SYSTEM_LINK_STATUS_EFAIL;
}


inputPtr = inPtr[0];

for(rowIdx = 0; rowIdx < height ; rowIdx++)
{
for(colIdx = 0; colIdx < wordWidth ; colIdx++)
{
/* Masking chroma component */

*(inputPtr+colIdx) &= mask;
*(inputPtr+colIdx) |= mask1;

}
inputPtr += (inPitch[0] >> 2);
}
return SYSTEM_LINK_STATUS_SOK;

}

 I Think that would be the reason, So how can I overcome this issue
