Is it possible to decode a H264 stream without IDR frames? Actually the IDR frame appears only at the start of the video and never again. So when the playing not starts from the begining, I can't decode the stream correctly. I found a comment about matroska on the internet:

mkvmerge: bug fix: Added support for handling SEI NALUs in
AVC/h.264 elementary streams so that "key frames" can be detected
even if no IDR slices are present.

Is this possible with IPP? Or is there any solution for this problem?
Best Regards,
