I capture a video but can't save it .How to halndle the problem via JMF?

Question

Hi everyone, I'm starting to use JMF and faced the problem
The problem is to save captured video in .avi or .mov formats.I managed to capture and play it in a player, but can't save it .On the other hand when I used processor to capture and save the video , I've succeeded .But my task is to combine these two actions. Give a hint please.
All kind of replies will be greatly appreciated.

You need to get the StreamWriterControl on the DataSink, rather than the Processor.I doesn't seem to work.
