is the number of B pictures (bidirectionally predictive

NOTE: Placing zeros in both
# P per GOP
and
# B per I/P
boxes
forces pictures to be I-frame only.
-
Open GOP
is a group of pictures that has a B picture as its last picture type
for the next I-frame, such as IBBPBBPBBI, and so on. An Open GOP
depends on the next GOP’s anchor to define its last B picture.

is the number of the last encoded line of video.
