void dec_ref_pic_marking

(

Bitstream *

currStream

)

read the memory control operations

Definition at line 528 of file header.c.

Here is the call graph for this function:

void decode_poc

(

ImageParameters *

img

)

To calculate the poc values based upon JVT-F100d2 POC200301: Until Jan 2003, this function will calculate the correct POC values, but the management of POCs in buffered pictures may need more work.

Returns:

none

Definition at line 608 of file header.c.

References error().

Referenced by fill_frame_num_gap(), and init_picture().

Here is the call graph for this function:

int dumppoc

(

ImageParameters *

img

)

A little helper for the debugging of POC code.

Returns:

none

Definition at line 809 of file header.c.

int FirstPartOfSliceHeader

(

Slice *

currSlice

)

read the first part of the header (only the pic_parameter_set_id)

Returns:

Length of the first part of the slice header (in bits)

Definition at line 76 of file header.c.

Referenced by read_new_slice().

Here is the call graph for this function:

int RestOfSliceHeader

(

Slice *

currSlice

)

read the scond part of the header (without the pic_parameter_set_id

Returns:

Length of the second part of the Slice header in bits

redundant_pic_cnt is missing here
