[speex-dev] Lost ogg sync using jspeex

[rthummal]

Hi
 
I am getting lost ogg sync exception when I tried to decompress a speex stream. I am using the following program for both compressing as well as decomressing. I am just planning to test how jspeex works.
 
// File AudioCapture.java

  Vector recordBuffer=new Vector();
  try
  {
   AudioFormat audioFormat = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED, 8000, 16, 1, 2, 8000, true);
   System.out.println("AudioFormat Created");
   DataLine.Info dataLineInfo = new DataLine.Info(TargetDataLine.class,audioFormat,8000);
   System.out.println("Dataline.Info Created");
   //DataLine.Info outputDataLineInfo = new DataLine.Info(SourceDataLine.class,audioFormat,44100);
   TargetDataLine targetDataLine = (TargetDataLine) AudioSystem.getLine(dataLineInfo);
   System.out.println("TargetDataLine Created");

Any kind of help would be very great
 
Thanks in advance...
