Comment (by markfilipak):

 > Again, Open GOP looks like this:
 > https://forum.videohelp.com/images/imgfiles/Df6d4pR.jpg

 What is that? Is it authoritative?
 \\
 > Open GOP needs to start with two B frames, yours starts with an I frame
 that is wrong.
 H.222, Quote: "After a GOP, the first picture shall be an I-picture". I
 believe it means "After a GOP **''header''**". I've never seen a GOP
 header that was followed by a B-frame in the same packet.
