picture automatically.
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.
