How to play a normal video in Super Slow Motion Mode in iPad

Question

I have created video player using AVPlayer. Video is playing very well. Now i am trying to play video in Super Slow Motion Mode. So i am changing frameRate value to 0.0001. But it seems AVPlayer unable to play in very slow mode. Kindly any expert suggest me or any other alternative.

This is play button clicked function.

- (void)playButtonPressed:(id)sender {
 [video1ControlView.player prepareToPlayVideo]; }


-(void)prepareToPlayVideo
{
if(self.outputFileInternal != nil)
{
    AVPlayer *currentPlayer  = [self player];
    currentPlayer.rate = self.frameRate; // here frameRate = 1 means, video play in normal play. if i will pass 0.25 then video will play slow mode but i want to play in **SUPER SLOW MOTION MODE**
    _playerStatus = PlayerStatusPlaying;
}
}
