Split an input packet into NAL units.
If data == raw_data holds true for a NAL unit of the returned pkt, then said NAL unit does not contain any emulation_prevention_three_byte and the data is contained in the input buffer pointed to by buf. Otherwise, the unescaped data is part of the rbsp_buffer described by the packet's H2645RBSP.
If the packet's rbsp_buffer_ref is not NULL, the underlying AVBuffer must own rbsp_buffer. If not and rbsp_buffer is not NULL, use_ref must be 0. If use_ref is set, rbsp_buffer will be reference-counted and owned by the underlying AVBuffer of rbsp_buffer_ref.
