Fast rewind trick mode playing ( I-frames only ) problems

Hi,

When I try to decode I-frame only H264 stream ( after removing all P and B frames - full IPBBBP... stream can be decoded without problems ) I get following sequence after calling DecodeFrameAsync() :

 - MFX_WRN_VIDEO_PARAM_CHANGED ( each I frame has SPS and PPS NALS repeated - but they are always the same ),

 - MFX_ERR_MORE_SURFACE

 - MFX_ERR_MORE_DATA ( mfxBitstream tells that all input data was consumed ),

and next I-frame gives me exactly the same results, so I always get MFX_ERR_MORE_DATA at the end and no output frame is produced. I set MFX_BITSTREAM_COMPLETE_FRAME flag but it changes nothing. How should I decode this stream ?

 

Thanks,

Kamil
