I am currently working on a video based application. I'm using MPMoviePlayerController to play the video which i had recorded in my app. My question is what I have to do to play the video in slow forward and backward motion in MPMoviePlayerController?

Answer 1

-(IBAction) playSlow:(UIButton *)sender{

    if (frameRate > 1) 
        frameRate -= 0.5;
    else
        frameRate -= 0.25;

    if (frameRate < 0) {
        frameRate=0;
    }

    queuePlayer.rate = frameRate;
}

-(IBAction) playFast:(UIButton *)sender{

    if (frameRate < 1) 
        frameRate += 0.25;
    else
        frameRate += 0.50;

    if(frameRate > 4)
        frameRate = 4;
    queuePlayer.rate = frameRate;
}
