int dec_ref_pic_marking	(	Bitstream *	bitstream,
		DecRefPicMarking_t *	p_drpm,
		int	idr_flag,
		int	no_output_of_prior_pics_flag,
		int	long_term_reference_flag

write the memory management control operations

Returns:

number of bits used

Here is the call graph for this function:

int Partition_BC_Header	(	Slice *	currSlice,
		int	PartNo
	)

int Partition_BC_Header () write the Partition type B, C header

Returns:

Number of bits used by the partition header

Parameters

PartNo: Partition Number to which the header should be written

Side effects

Partition header as per VCEG-N72r2 is written into the appropriate partition bit buffer

Limitations/Shortcomings/Tweaks

The current code does not support the change of picture parameters within one coded sequence, hence there is only one parameter set necessary. This is hard coded to zero.
