JMF video frame size

[rosmi]

I need to know dimension of the media file played by
javax.media.bean.playerbean.MediaPlayer

I use the code you can see below:

FormatControl formatControl = (FormatControl)
this.mediaPlayer.getControl ("javax.media.control.FormatControl");
VideoFormat videoFormat = (VideoFormat) formatControl.getFormat();
return videoFormat.getSize();

mediaPlayer is known object from another class.

But I get formatControl == null.

It's very very strange, but just one time this code did work.

So I have no idea ... Someone else?
