get duration on player

Hi,

I am using a jmf player to play an mpeg video. I want to knw the duration of the mpeg for which i use the getDuration() method. But this often returns DURATION_UNKNOWN. to get the duration I am puttin it in a while loop. But sometimes the complete duration is not obtained. How to do this?

I am attaching code snippet.

Thanks

/*start the player*/

player.start();

/*Define Time duration of mpeg/mp3 file*/

Time duration = player.getDuration();

/* Check proper time of playing file which is obtained

from function */

while(duration == Duration.DURATION_UNKNOWN){

duration = player.getDuration();

}

/*find the total time of the video/audio file in milliseconds*/

mpegTime = (int)(duration.getNanoseconds()/1000000);
