Help with ippiDequantTransformResidualAndAdd_H264_16s_C1I

Hi,

can I use the same pointer as arg #1 and arg #4 when calling ippiDequantTransformResidualAndAdd_H264_16s_C1I?

That is:

ippiDequantTransformResidualAndAdd_H264_16s_C1I(
pPredDst,
pSrcDst,
pDC,
pPredDst, // same pointer
PredDstStep,
PredDstStep, // same step
QP,
AC);

The purpose is when the transformed-quantified predictor is already stored in the frame that is to be reconstructed.

Other question: does there exist a version of ippiPredictIntra_4x4_H264_8u_C1IR taking an explicit pDst? That is:

IJG on PCA

I just bought the IPP library after reading the marketing white paper that claimed that the latest IPP supported the same jpeg interfaces on desktop windows and WinCE. I was sorely dissapointed to find that the IJG jpeg library sample, which works beautifully on the desktop, doesn't even compile with the PCA IPP, for lack of several api calls. The jpeg sample provided for the PCA lib is clearly inadequate, so I am a little confused about what Intel expects developers to do here. Are we all supposed to go out and build our own IJG lib equivalents? Am I missing something?

gray scale morphology with non-flat structure element?

Hi,

I try to find erosion and dilation operators in IPP4.0 for gray scale morphology. but it seemsthatonly flat structure element could be defined. Is it possible to use the present operators to construct some operators for 3d (non-flat) structure element?

I think it only needssome addition or subtraction operation in the source code.

Should modern IA-32 processors classify as CISC or RISC?

It seems like modern IA-32 processors are more like a hybrid of RISC and CISC. But of all the text books I've read, IA-32 is classified as CISC processors. However, I can't find any official papers that state it clearly whether modern IA-32 processor, say Pentium 4, is a RISC processor or CISC processor.

I'm hoping thatany intel engineers herewould give me a definite answer to it. Thank you very much.

chroma resampling

Hi,
I need to create an mpeg file with random frames !! that being the intention .. I started with frames having values (each frame has same values across the pixels)

y = random number from 0 - 255
u = 0
v = 0

seem to give an greenish tinge on playing the created mpeg2 file.
obviously the chroma values that i am setting are wrong.

then i tried doing ..
Ipp8u *yuv; // [3]
yuv = rgb2yuv(random_number);
y = yuv[0];
u = yuv[1];
v = yuv[2];
