DecodeInit

Initializes the memory for the G726 decoder.

Syntax

IppStatus ippsDecodeInit_G726_8u16s (IppsDecoderState_G726_16s* pDecMem, IppSpchBitRate rate, IppPCMLaw law);

Parameters

pDecMem	Pointer to the input memory buffer of size needed to properly initialize the G.726 decoder.
rate	Decode bit rate of the G.726 decoder, must be one of IPP_SPCHBR_16000, IPP_SPCHBR_24000, IPP_SPCHBR_32000, or IPP_SPCHBR_40000.
law	Output speech PCM law: must be one of IPP_PCM_MULAW, IPP_PCM_ALAW or IPP_PCM_LINEAR.

Description

The function ippsDecodeInit_G726 is declared in ippsc.h file. This function initializes the memory given by the pointer pDecMem to enable ADPCM decompression starting from the reset state.

Return Values

ippStsNoErr	Indicates no error.
IppStsNullPtrErr	Indicates an error when the pDecMem pointer is NULL.
ippStsBadArgErr	Indicates an error when rate or law has an illegal value.
