Hi, can any one tell me how i can seek my mp3 file to a particular position 
using time stamp.
 i used soundGrabber.setTimestamp(startTime); and want to grab frame till the end of file but it seems soundGrabber.grabFrame() does't move to next frame, not a single time.

while(soundGrabber.getTimestamp()<=soundGrabber.getLengthInTime()){
                    try {

                        recorder.record(soundGrabber.grabFrame());

                        //Log.v("sound time stamp", ""+soundGrabber.getTimestamp()/1000000);
                    } catch (com.googlecode.javacv.FrameRecorder.Exception e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    } catch (com.googlecode.javacv.FrameGrabber.Exception e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    catch(java.lang.Exception e){}
                }

I've added support for that in this revision FFmpegFrameGrabber:
http://code.google.com/p/javacv/source/detail?r=badc3b3b7d85028a457542e71acfdb72

Let me know if that works as expected, and thanks for reporting!
