Hi all,

I used IPP with PJSIP to integrate g729 codec in our VOIP software.

There is a much backgoround noise disturbance when we talk, and the voice

can't recognized properly, Please suggest me, is there something to do

with pjsip code or is there any other issues with the intell ipp codecs?

Hi,

This looks a duplicated problem with the following:
http://software.intel.com/en-us/forums/showthread.php?t=78800

So we can combine the problem into that thread.

thanks,
Chao

Man
I have a problem in the "Encode" G729. The encoding this strange. I go with 160 bytes as buffer below and get 10 bytes in G729. It seems to me that the result is not in G729a format.

Anyone ever had a problem with this?

Hi Fernando,

Is the situation (I mean codec output) reproducible with "usc_speech_codec" application?
