G711 codec & rtp

[valexey]

I receive 20-ms G711 frame (160 byte), add 2 byte header and push it ti ASP-queue.

There is src (yep, it is ugly):

    TUint8 buf[162];
    buf[0]=0x01;
    buf[1]=0x00;
    for (int i=0; i<160; i++)
    {
        buf[i+2]=aPayloadData[i];
    }
    TPtr8 frame(buf,162);

    TAPSCommBuffer RTPbuffer;
    RTPbuffer.iBuffer.Copy(frame);
    outQueue->Send(RTPbuffer); // RMsgQueue<TAPSCommBuffer>* outQueue;

There is no sound. And after some time application crashs.

What's wrong?

PS. I test it on E65 device.

Hi,

I was also facing the same problem, but i am using the following code snippet

TUint8 buf[2];
buf[0]=0x01;
buf[1]=0x00;
RTPbuffer.iCommand = EAPSPlayData;
RTPbuffer.iStatus = KErrNone;
RTPbuffer.iBuffer.Append(buf,2);
RTPbuffer.iBuffer.Append(aPayloadData);

Now i can hear the audio clearly at receiving end

Use the above code snippet on adding 2-byte header to the payload, this works for me atleast.
