How the g726 encode IPP functions support PLC ?

[sengacheng]

Hi ,

we work on the codec sample code.

It seems the g711 support the PLC.

Is that correct ?

How about the g726 ?

Because the encoding is

doing by a function ippsEncode_G726_16s8u

and it accept uniform PCM.

Is it the PLC need to bedone before the Encode function or

the Encode functioninclude some extra PLC

Thanks for anyone can answer this question

Hi, Norman.

You absolutely right about G.711 codec. It has got VAD and PLC blocks. They were taken from G.729.

As for G.726. It hasn't got PLC (Packet Lost Concealment). USC implementation of G.726 just emulates lost packets with zeros inbitsream. You can use this emulation just passing NULL "in" pointer to the Decode() function.
