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
