Why is happened the difference during H264 encoding?

[nrson]

Hi, All

I have a meet the problems during tesing H264 fielding coding on IPP(Ver.7.0.5.059).

I set the parameter for fielding as following:

    coding_type = 1;

But there is the difference a generated bitstream according to image.

one(A) is general H264 bitstream, other(B) is strange H264 bitstream.

The decoing result of A is good, but B's bitstream is as following and not decoding.

 00 00 00 01 21 B8 04 07 4B ED 4B 1D FF 9C 6F FC 16 B3 A1 AB C4 AB F9 9D EA BB 6E 39 48 56 F8 A4 C5 3B 3D 08 65 C9 75 00 F1 B1 18 0B 71 A2 80 8E 39 B9 E9 F9 96 4A B1 30 A4 83 59 A9 8C 60 63 5A 4E 2F 14 A0 5B 77 94 AA B3 A1 03 51 5A 2D A2 97~~~~

I think that SPS and PPS of B is wrong or fielding coding is incompletely.

How do I solve the problem or advice?

Best regards,
