Function Documentation

ff_rl_init_level_run()

void ff_rl_init_level_run	(	uint8_t	max_level[MAX_LEVEL+1],
		uint8_t	index_run[MAX_RUN+1],
		const uint8_t	table_run[],
		const uint8_t	table_level[],
		int	n
	)

Initialize max_level and index_run from table_run and table_level; this is equivalent to initializing RLTable.max_level[0] and RLTable.index_run[0] with ff_rl_init().

ff_rl_init()

void ff_rl_init	(	RLTable *	rl,
		uint8_t	static_store[2][2 *MAX_RUN+MAX_LEVEL+3]
	)

Initialize index_run, max_level and max_run from n, last, table_vlc, table_run and table_level.

Parameters

static_store

static uint8_t array[2][2*MAX_RUN + MAX_LEVEL + 3] to hold the level and run tables.

Note

This function does not touch rl_vlc at all, hence there is no need to synchronize calls to ff_rl_init() and ff_rl_init_vlc() using the same RLTable.

ff_rl_init_vlc()

void ff_rl_init_vlc	(	RLTable *	rl,
		unsigned	static_size
	)

Initialize rl_vlc from n, last, table_vlc, table_run and table_level.

All rl_vlc pointers to be initialized must already point to a static buffer of static_size RL_VLC_ELEM elements; if a pointer is NULL, initializing further VLCs stops.

Note

This function does not touch what ff_rl_init() initializes at all, hence there is no need to synchronize calls to ff_rl_init() and ff_rl_init_vlc() using the same RLTable.
