Scrol bar to slow down a video and audio file

you want a video to play at something other than its native framerate?

if yes, you can't easily do that with an flvplayback component.  you'll need to separate the audio and visual parts of your video and had them to a movieclip timeline.  then you'll need to customize the playback speed of that movieclip.

you can use the following to play any movieclip (forward or backward) at any speed:

function playF(mc:MovieClip, m:int, n:int, fps:int):void {

    var playFFF2:Function = function(mc:MovieClip):void {

        trace(getTimer(),mc.currentFrame);

        if (mc.m<mc.n) {

            mc.nextFrame();

        } else {

            mc.prevFrame();

        }

        if (mc.currentFrame == mc.n) {

            clearInterval(mc.int);

        }

        //updateAfterEvent();

    };

    mc.m = m;

    mc.n = n;

    mc.fps = fps;

    mc.gotoAndStop(mc.m);

    clearInterval(mc.int);

    mc.int = setInterval(playFFF2, 1000/mc.fps, mc);

}

// and to stop it:

function stopF(mc:MovieClip):void {

    clearInterval(mc.int);

}
