Comment (by rycius):

 Ok, i have tried to find bad commit by playing around with git bisect, and
 ended with:
 {{{
 git bisect bad
 1f26a231bb065276cd80ce02957c759f3197edfa is the first bad commit

     qsv: Merge libav implementation

     Merged as-at libav 398f015, and therefore includes outstanding
     skipped merges 04b17ff and 130e1f1.

     All features not in libav are preserved, and no options change.

 }}}

 it looks like refusal to use external SPS parser
 MFXVideoDECODE_DecodeHeader() broken decoding.
