Comment (by Balling):
Okay, first of all I immediatelly found a bug in Elecard in frame 80 on
this sample. Does not happen in ffmpeg or in VQ Analyzer.
Anyway, yes. The first B frame in the GOP (again, in coded order GOP
begins with I frame, in presentation/display it is I frame) depends on P
frame from the previous GOP, https://i.imgur.com/Y9tduBw.png
Then I verified whether the non-IDR I frame is actually a recovery point,
it is. exaqct_match 1 checks out.
