Help Using VAS

[bilaldurrani]

Hi,

I am trying to use VAS to send/receive data. The DnLink and UpLink codec initialization is going perfect and the loopback example worked as well. I did some changes, but the problem is that EmptyBuffer is being called only once and then FillBuffer is called as long as the application is running. Code snippet:

void CVoIPTestEngine::EmptyBuffer(const CVoIPAudioUplinkStream& /*aSrc*/,
                                  CVoIPDataBuffer* aBuffer)
{
    DEBPRN0(_L("CVoIPTestEngine::[0x%x]::EmptyBuffer :>"));
    aBuffer->GetPayloadPtr(iRecBufPtr);
    
    //GIVE DATA TO SEND
    iCallBack.giveDATA(iRecBufPtr);

    iVoIPUplink->BufferEmptied(aBuffer);
}


void CVoIPTestEngine::FillBuffer(const CVoIPAudioDownlinkStream& /*aSrc*/,
                                 CVoIPDataBuffer* aBuffer)
{
	
    DEBPRN0(_L("CVoIPTestEngine::[0x%x]::FillBuffer"));
    aBuffer->GetPayloadPtr(iPlayBufPtr);

    //GET RECEIVED DATA
    iCallBack.getDATA(iPlayBufPtr);
    iPlayBuf->SetPayloadPtr(iPlayBufPtr);
    iVoIPDnlink->BufferFilled(iPlayBuf);
}

I am using ILBC Codec and the Buffer size i get is 40. What am i doing wrong here. I previously used the DoLookBack function that is in the original example and things were working fine, but why is that it is not working this way? Also i thought that maybe iPlayBufPtr's length and maxsize are wrong or something, so i copied the structure of a "Filled" iRecBufPtr once and still it didnt work. What is the problem here?

hmmm i tried to delete this thread, i copied this General Symbian C++ because somehow feel the VoIP discussion wont cater this.
