Capturing video to a file while transmitting it over the network

Question

I have tried several ways to do this but non of them have worked. On the JMF Programmers Guide its stated that one could do something like this: creating a processor from a DataSource, and the taking two Datasources from the processor, one is used to transmitt the video over the network, and the other is used to save the data to a file(through a DataSink).
One of the ways I've tried is to clone de DataSource before creating the Processor. I've also tried to clone the Data source after creating and realizing the processor. The other way I've tried is by using the JMFSolution "Video Capture Utility with Monitoring", found at the jmf's homepage, which intercepts the data carried from the capture data source to the Processor.
Non of these have worked, and I always get Exceptions about not finding a DataSink for the DataSource I use. For example:
"javax.media.NoDataSinkException: Cannot find a DataSink for: com.sun.media.multiplexer.RawBufferMux$RawBufferDataSource@d9850" ;
"javax.media.NoDataSinkException: Cannot find a DataSink for: com.sun.media.vfw.PushBufferDataSource@1e45"
I've search the Web triying to find something clear about capturing video to a file while transmitting it over the network, but nothing seems to work.
I would appreciate a piece of an advice on this.

Answer 1

you can try modifing de Capture example from JMF Solutions.
change this function:
public int startCapture() {
     int result = -1;
     enableComponents(false);
     buttonStart.setLabel("Pause");
     buttonEnd.setEnabled(true);
     startMonitoring();
     try {
processor.start();
DataSource clone = Manager.createCloneableDataSource(datasource);
     MediaLocator ml2 = new MediaLocator("file://capture.mov");
System.out.println("Content Type " + clone.getContentType());
datasink = Manager.createDataSink(processor.getDataOutput(), ml2);
     datasink.open();
datasink.addDataSinkListener(this);
     datasink.start();
result = 0;
     } catch (Exception e) {
     System.err.println("DataSink Exception " + e);
result= -1;
