Audio Buffer over flow issue in AudioRecord

[GoogleCodeExporter]

Hi,
 Iam using the latest sipdroid code . I am having Audio Buffer overflow in
audiorecord , and the audio RTP layer is tearing down , bringing down the
whole call. Can you please let me know what could be the issue. I am using
G.711 codec.

Thanks,
Anu

Thanks for the reply. No after the buffer overflow, my call gets disconnected. 
Iam
using G1. I tried increasing the buffer size in AudioRecord , it didnt 
help.This is
what I see in the logcat.

Do your calls work for a while? (before the buffer overflow)

It works for around 20-30 seconds or so.

Buffer overflows in AudioRecord are normal. We have already begun reducing them 
but I 
don't think they have anything to do with your calls getting disconnect. There 
is a 
timeout of 22 seconds no RTP received the call gets hung up. Do you hear the 
other end?

Thanks a lot. It helped. I was using a send-only stream , but didnt set 
recv-only to
false. So that was the reason it was timing out on RtpReceiveStreamer. Thanks a 
lot ,
now I see my audio line stay up.

Just a question, how do you set two devices such that one is send-only and the 
other
is receive-only? What things are to be added/modified/removed in the two sets of
codes to make a test like this without the 22 second time out being triggered?

hi,
I konw one reason:
if you "new MediaRecorder" >= twice and first MediaRecorder not do" = null", 
then must happen :"buffer overflow".

Hope useful for you ^_^
