MOV vs AVI, ClassCastException when opening DataSink

Question

Hi,
I'm a little confused here. I've got this application that's reading an AVI file, doing some processing on it and the passing the processed data to file. I set the output content type of the processor like this:
  processor.setContentDescriptor(new ContentDescriptor(FileTypeDescriptor.QUICKTIME));This works fine and a resulting .mov is produced. However, if I change the contenttype to MSVIDEO (in order to produce an .AVI file) I get the following ClassCastException:
java.lang.ClassCastException
  at com.sun.media.multiplexer.video.AVIMux.writeFrame(AVIMux.java:398)
  at com.sun.media.multiplexer.video.AVIMux.doProcess(AVIMux.java:374)
  at com.sun.media.multiplexer.BasicMux.process(BasicMux.java:274)
  at com.sun.media.BasicMuxModule.connectorPushed(BasicMuxModule.java:406)
  at com.sun.media.BasicOutputConnector.writeReport(BasicOutputConnector.java:120)
  at com.sun.media.BasicFilterModule.process(BasicFilterModule.java:408)This occurs when the following lines of code are executed:
      datasink = Manager.createDataSink(dataSource, outMediaLocator);
      datasink.open();  // <-------- This gives the exceptionReally apprciate any comments, ideas, etc.. on this as for now I'm not able to produce .AVI files :-(

Hi Jennifer,
I use the following code (and it works perfectly)
processor.setContentDescription(new FileTypeDescriptor(FileTypeDescriptor.MSVIDEO));
Hope that helps you.
