int FmoGetLastMBOfPicture

(

FmoGetLastMBOfPicture() returns the macroblock number of the last MB in a picture. This mb happens to be the last macroblock of the picture if there is only one slice group.

Input:

None

int FmoGetNextMBNr

(

int

CurrentMbNr

)

FmoGetNextMBBr: Returns the MB-Nr (in scan order) of the next MB in the (scattered) Slice, -1 if the slice is finished.

Parameters:

CurrentMbNr

number of the current macroblock
