Decode Mpeg2 Intra-Slice

Hello.

I try to develop mpeg 2 decoder with Intel IPP.

I want to decode Intra-Slice(P-Frame only) mpeg2 stream with it.

I use UMC::MPEG2VideoDecoder(Intel IPP Sample ver 7.1.1.013) for it.

But, if i try to decode, UMC::MPEG2VideoDecoder always return VM_NOT_ENOUGH_DATA.

So, I have question, Is it possible to decode Intral-Slice mpeg2 frame with it ?

If it posslibe, how can I decode it ?

Please advice to me.

Thank you.
