Seeking not allowed on media in blackberry video player

I have created a video player which retrieves data from the server and plays. The content type is Video/mp4. When I try to rewind the video I get ERROR:Seeking not allowed on media

Per the API documentation, setMediaTime(int) does not support certain media types. What media types does the player support and is there any work around to rewind the vide开发者_如何学Goo?

rewind() {
   _player.setMediaTime(0);
   _player.start();
}
