IPP 5.1 MPEG4 GetFrame() distorted image

[aeropriest]

I am using GetFrame() of MPEG4 decoder in DirectShow. The renderered image does not show correct image. I have set output to YUY2. I have crossed checked with sample code with IPP and everything seems all right. Following is the code

MediaData p_dataIn;
VideoData p_dataOut;

int err_code = 0;
int mRetval;

p_dataIn.SetBufferPointer((vm_byte *)pSrc,lSrcLen);
p_dataOut.SetBufferPointer(pDest,*lDestLen);

mRetval = GetFrame(&p_dataIn,&p_dataOut);

if( mRetval == UMC_OK )
{
int nRet = p_dataOut.GetDataSize();
}


In the above code
pDest = pointer to the DirectShow buffer from IMediaSample
*lDestLen = length of the buffer.

Thanx in advance

Hi!

Does lSrcLen and lDestLen are the same type? Because if they are, then you should use *lSrcLen instead of lSrcLen. What is the color format of the source video?

And I also think, you shoud use

yourrenderervariable.LockInputBuffer(&p_dataOut); before thge GetFrame() and
yourrenderervariable.UnLockInputBuffer(&p_dataOut); after the GetFrame().
