BD_PRIVATE int graphics_processor_decode_pes	(	PG_DISPLAY_SET **	s,
		struct pes_buffer_s **	buf,
		int64_t	stc
	)

Decode data from MPEG-PES input stream.

Only segments where DTS <= STC are decoded. If STC < 0, all segments are immediately decoded to display set.

All decoded PES packets are removed from buffer.

Parameters:

	s	display set
	buf	data to decode
	stc	current playback time

Returns:

1 if display set was completed, 0 otherwise

BD_PRIVATE int graphics_processor_decode_ts	(	GRAPHICS_PROCESSOR *	p,
		PG_DISPLAY_SET **	s,
		uint16_t	pid,
		uint8_t *	unit,
		unsigned	num_units,
		int64_t	stc
	)

Decode data from MPEG-TS input stream.

Segments are queued and decoded when DTS <= STC. If STC < 0, all segments are immediately decoded to display set.

Parameters:

	p	GRAPHICS_PROCESSOR object
	s	display set
	pid	mpeg-ts PID to decode (HDMV IG/PG stream)
	unit	mpeg-ts data
	num_units	number of aligned units in data
	stc	current playback time

Returns:

1 if display set was completed, 0 otherwise
