After encoding IDR picture, I picture period
calculation is reset to initial state. For example, if
host set [IdrPic] flag set 18th frame and
[EncGopNum] is 15, encoded picture types are
1st frame : I (IDR - automatically)
2nd frame : P
...
14th frame : P
15th frame : I
16th frame : P
17th frame : P
18th frame : I (IDR – set by host)
19th frame : P
...
32nd frame : I
33rd frame : P
...
In MPEG-4/H.263 case, I(Intra) picture is
sufficient for decoder refresh
Host must set this filed as "1" periodically for
inserting decoder refresh point in encoded bit
stream.
Function
Encoded frame number.
After BIT encodes one frame, BIT increase
