diferences Movie.fromFile & Movie.fromDataRef

Hi All

 

I have write a program for view several video tracks like a mosaic.

It works if the mp4 file is local

...

     mMovie = Movie.fromFile (omf);

     int numTracks = mMovie.getTrackCount();

...

 

numTracks is OK

 

but if the file is served by Darwin Streaming server

 

...

          String url ="">

              javax.swing.JOptionPane.showInputDialog (null,

                                              "Enter URL");

          DataRef dr = new DataRef (url);

          mMovie = Movie.fromDataRef (dr,

                                 StdQTConstants.newMovieActive);

         int numTracks = mMovie.getTrackCount();

 

...

 

numTracks is 1 when the file has several tracks

 

Someone knows why?

Thanks

 

 

Best Regards,
