Function Documentation

g722_1_decode_state_t* g722_1_decode_init	(	g722_1_decode_state_t *	s,
		int	bit_rate,
		int	sample_rate
	)

Initialise a G.722.1 decode context.

Parameters:

s	The G.722.1 decode context.
bit_rate	The required bit rate for the G.722.1 data. The valid rates are 48000, 32000 and 24000.
sample_rate	The required sampling rate. The valid rates are 16000 and 32000.

Returns:

A pointer to the G.722.1 decode context, or NULL for error.

int g722_1_decode_release

Release a G.722.1 decode context.

Parameters:

s	The G.722.1 decode context.

Returns:

0.

int g722_1_decode_set_rate	(	g722_1_decode_state_t *	s,
		int	bit_rate
	)

Change the bit rate for an G.722.1 decode context.

Parameters:

s	The G.722.1 decode context.
bit_rate	The required bit rate for the G.722.1 data. The valid rates are 48000, 32000 and 24000.

Returns:

0 for OK, or -1 for a bad parameter.
