                                    guint* nal_size)

Converting a bit stream into a real nal packet. If the bit stream already has a start code, it will be replaced by the new one specified by the nal_prefix_size and packetized. It is assured that the output aligns to the byte and the all the emulations are inserted.

Parameters:

nal_prefix_size

the size in bytes for the prefix of a nal, may be 2, 3 or 4

packetized

whether to write the bit stream in packetized format, which does not have the start code but has a nal_prefix_size bytes' size prepending to the real nal data

has_startcode

whether the input already has a start code

add_trailings

whether to add rbsp trailing bits to make the output aligned to byte

raw_data

the input bit stream

raw_size

the size in bits of the input bit stream

nal_data

the output bit stream converted to a real nal

nal_size

the size in bytes of the output

Since : 1.22
