Function Documentation

int g722_encode (  g722_encode_state_t *  s, uint8_t  g722_data[], const int16_t  amp[], int  len )

Encode a buffer of linear PCM data to G.722 Parameters: s  The G.722 context. g722_data  The G.722 data produced. amp  The audio sample buffer. len  The number of samples in the buffer. Returns: The number of bytes of G.722 data produced.

g722_encode_state_t* g722_encode_init (  g722_encode_state_t *  s, int  rate, int  options )

Initialise an G.722 encode context. Parameters: s  The G.722 encode context. rate  The required bit rate for the G.722 data. The valid rates are 64000, 56000 and 48000. options  Returns: A pointer to the G.722 encode context, or NULL for error.
