EncodeMux_AMRWBE

Encodes and multiplexes subvectors into several packets.

Syntax

IppStatus ippsEncodeMux_AMRWBE_16s(const Ipp16s* pSrc, int nSubvectors, const int* pPacketSizes, Ipp16s* pDstParams, int nPackets);

Parameters

pSrc	Pointer to the rounded subvectors [nSubvectors*8 + nSubvectors].
nSubvectors	Number of subvectors.
pPacketSizes	Pointer to the vector of size of each packet [nPackets].
pDstParams	Multiplexed parameters [( pPacketSizes[0]+3)/4 +...+ (pPacketSizes[nPackets]+3)/4].
nPackets	Number of packets.

Description

The function ippsEncodeMux_AMRWBE is declared in ippsc.h file. This function encodes the TCX parameters and puts them in one or several binary packets for transmission.
