ff_h2645_packet_split()

int ff_h2645_packet_split	(	H2645Packet *	pkt,
		const uint8_t *	buf,
		int	length,
		void *	logctx,
		int	nal_length_size,
		enum AVCodecID	codec_id,
		int	flags
	)

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, H2645_FLAG_USE_REF must not be set in flags. If H2645_FLAG_USE_REF is set in flags, rbsp_buffer will be reference-counted and owned by the underlying AVBuffer of rbsp_buffer_ref.
