APS Implementation

Great. I am currently in Dhaka. Which operator are you using to connect to
your server? Grameen or Banglalink? 

Seems like both of them not working for me. They are using some sort of 10
series IP and I detect NAT? Did you face this?

I dont think APS implementation(G729) is so hard as you think. APS already
has G729 codec support that is if i use APS i must get the implementation of
g729 innerly . i just have to change the procedure to use g729 codec....like
some parameter and encoding decoding technique. ...

APS use 24byte data ...thats a point also...

I don't think you can with this current wrapper.

So far I understood, the current wrapper just take PCM and convert that to
g.711 and pass it to APS and vice versa. You still need your own g.729
implementation. This wrapper just take PCM as input and output..

 

Correct me if I were wrong..

Hi Pai,



Can you please tell me if i want to g729 from Aps what should i need to do?

in the line of encoder mode

iSession.SetEncoderMode(EALawOr20ms);    

is for g711 but i saw no encoding mode for g729 . should i block those line
if i want to use g729?

Thanks

Hi,


in source symbian_sound_aps.cpp:

void CPjAudioEngine::RecCb(TAPSCommBuffer &buffer)
{
...
buf[i] = pjmedia_alaw2linear(iBuffer[i]);
...
}

TInt CPjAudioEngine::StartStreamL()
{
....
iSession.SetEncoderMode(EALawOr20ms);
iSession.SetDecoderMode(EALawOr20ms);
...
}

audio is in G711-A Format.


The  APS supports the following codecs: AMR, G711, G729 and iLBC.

If you like use other codec for encoding or decoding, you should change the
SetEncoderMode() and SetDecoderMode().

How does APS implementation works in Symbian_ua?

Does g711,gsm,speex all works fine?

 

APS->G711->PCM->gsm

Or 

APS->gsm??

 

Does it do the transcoding or it just only works for g711 and not gsm and
speex?

 

thanks
