I do remember rejecting the even more broken 
"callbacks to count the number of buffered frames" and i suspect i told you
back then that the timestamps should be given to the decoder to reorder them.
Maybe you rejected this and i then suggested to use has_b_frames, but if my
guess (and this is only a guess) is true it would really be more a
"least broken solution within the constraints" not a "working solution"

Breaking DRM is a little like attempting to break through a door even
though the window is wide open and the only thing in the house is a bunch
of things you dont want and which you would get tomorrow for free anyway
