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).
