Save audio and video signals in diferents files

Question

Hi!!, How can i save the audio and video signals in diferent files?
I get the signals with:
for (int i = 0; i < tc.length; i++) {
        if ( (tc.getFormat() instanceof VideoFormat)) {
     this.VideoTrack= tc[i]
}else{
     if ( (tc[i].getFormat() instanceof AudioFormat))
          this.AudioTrack= tc[i];
Thanks                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       

Answer 1

Ok, I've separated the tracks and i've saved the Audio signal in a file, but it save the full audio track and i only want save 10 seg.
I`m using
DataSink dsink=Manager.createDataSink(procesor.getDataOutput(), ml);
                         dsink.open();
                         dsink.start();
                         this.procesor.start();
                         Thread.sleep(10000);
                         this.procesor.close();
                         dsink.close();Thanks!!
