how to break a video data to macroblocks?

I see some of your image processing functions process only macroblock instead of entire video data, like GetDiff16x16.
My questions are,
Is there a way to use ipp break video data into blocks?
How do I store those blocks?
How do I merge those blocks to one video data after processing?
Thanks,

Hi ezcom,

Maybe you can have some clarification about your questions: Do you want to get data of the each decoded macroblock? IPP decoding sample returns the whole frame data (GetFrame()). For example, in H.264, if you only want to get the macroblock data, you only need to access the data with 16x16 block for luma or 8x8 block for chroma

Thanks,
Chao

I was wondering how to set parameters or data pointers when using macro block functions. I've figured out after few test.

Thanks for the answer, Chao.
