ilbc_encode()

int ilbc_encode	(	ilbc_encode_state_t *	s,
		uint8_t	bytes[],
		const int16_t	amp[],
		int	len
	)

Encode a buffer of linear PCM data to iLBC

Parameters

s	The iLBC encode context.
bytes	The iLBC data produced.
amp	The audio sample buffer.
len	The number of samples in the buffer.

Returns

The number of bytes of iLBC data produced.

ilbc_encode_init()

ilbc_encode_state_t* ilbc_encode_init	(	ilbc_encode_state_t *	s,
		int	mode
	)

Initialise an iLBC encode context.

Parameters

s	The iLBC encode context.
mode	The frame size.

Returns

A pointer to the iLBC encode context, or NULL for error.
