Comment (by JEEB):

 Yes, I do wonder what the meaning of that check is in mxfdec, in which
 cases is it /meant/ to need to set that parser flag (yes, video is not
 data, but the !FrameWrapped check was then later added in
 00a2652df3bf25a27d174cc67ed508b5317cb115 ).

 Otherwise all video streams only get `st->need_parsing =
 AVSTREAM_PARSE_HEADERS;` set for themselves, which I think should not make
 this problem happen?
