Comment (by blm-ubunet@…):

 HD-PVR etc are all old-school IDR H264..

 The root cause of the problem is a bug in H264Parser.cpp when detecting
 "keyframe" in AVC.

 The meat of the change is this line 1065..
 {{{
 au_contains_keyframe_message = (recovery_frame_cnt >= 0);
 }}}

 I'm still not (yet) getting exact agreement with ffprobe (very close) but
 there are no completely wrong values as before & seeking is better.
 The exact definition of "keyframe offset" w.r.t AVC sliced refresh is
 unclear (to me).
