int fmo_init

(

ImageParameters *

p_Img

)

FMO initialization: Generates p_Img->MapUnitToSliceGroupMap and p_Img->MbToSliceGroupMap.

Parameters:

p_Img

image encoding parameters for current picture

int FmoGetLastMBInSliceGroup	(	ImageParameters *	p_Img,
		int	SliceGroup
	)

FmoGetLastMBInSliceGroup: Returns MB number of last MB in SG.

Input:

SliceGroupID (0 to 7)

int FmoGetLastMBOfPicture

(

ImageParameters *

p_Img

)

FmoGetLastMBOfPicture(p_Img) 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

Here is the call graph for this function:

int FmoGetNextMBNr	(	ImageParameters *	p_Img,
		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:

	p_Img	image encoding parameters for current picture
	CurrentMbNr	number of the current macroblock
