I'm developing a blackberry application that plays video from the server. I've used Player.start() and Player.stop() for playing and pausing a video. But I also need rewind, forward and seek bar controls in my application. I tried using FramePositioningControl for these controls. But the following code is returning null.

FramePositioningControl framePositioningControl =
        (FramePositioningControl) player.getControl("FramePositioningControl");

I searched several forums and they say many players do not support FramePositioningControl. What players support FramePositioningControl? And what else should I do to add these controls in my application?
