Call recording gives empty .wav file when using via JNI

[anand prajapati]

I want to record the call in a file using the Java API. I created audio media recorder as stated in the documentation and started transmission from the call's media to the recorder's media. I have been trying it since yesterday. Still I am getting an empty file every time. I used following snippet :-

public void startRecording(String filePath) {
  AudioMedia callMedia = getAudioMedia();
  try {

   // disconnect previous bridges before creating new one
    stopAudioMediaFlow();

    mediaRecorder = new AudioMediaRecorder();
    mediaRecorder.createRecorder(filePath);
    callMedia.startTransmit(mediaRecorder);
  } catch (Exception exc) {
    Logger.error("Error in recording audio ", exc);
  }
}

Any help in this issue will be highly appreciated.

I forgot to stop the recorder. Following did the trick.

public void stopRecording() {
  try {
    AudioMedia callMedia = getAudioMedia();
    if (mediaRecorder != null) {
      callMedia.stopTransmit(mediaRecorder);
      // close the recorder
      mediaRecorder.delete();
    }
    mediaRecorder = null;
  } catch (Exception exc) {
    Logger.error("Error in stopping recording.", exc);
  }
}
