If I understand correctly, you want to play (and display?) a video, whilst at the same time analysing the audio track? If so, that should be possible...
When you construct the VideoDisplay you have to pass in the audio (an AudioStream); if you write your audio analyser as a subclass of AudioProcessor, you can then construct your AudioProcessor with the original AudioStream object and pass your processor to the VideoDisplay constructor/factory method. When the video plays your AudioProcessor object will receive each sample chunk of the underlying audio as it is being requested by the VideoDisplay.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
