H264 decode problem

Hi..

I receive data from ip camera , data as follows:

00 00 00 01 67 42 00 28 e9 01 60 7b 20 00 00 00 01 68 ce 38 80 00 00 00 01 65 88 87 81 71 08 89
80 10 16 7b 80 0d 0e 3b 90 37 9c 29 53 d5 e1 bc 0c 00 29 50 7c ab 55 60 49 2b bd a5 14 29 de 08 .......

The datas contain nal SPS,PPS and IDR,I push data to Intel H264 codec
(http://software.intel.com/en-us/articles/getting-started-with-intel-ipp-unified-media-classes-sample/ )
, but codec always return ERROR( H264Decoder.GetFrame ),I don't know why, the same data push to ffmpeg codec is ok.

it's important how you do init(), read the thread named H264 NAL unit, it helped me with similar problems :

and try this order (per Mikls Szeles) -

- Init with SPS NAL Unit
- GetFrame with SPS NAL Unit
- GetFrame with PPS NAL Unit
- GetInfo with PPS NAL Unit

then proceed with other NALUs
