Controlling volume in 1 frame FLV

Sorry quick question.

What do I put in between {} on the first function where you have notated //your fading code...or do I leave it blank

Thanks for your help

First of all you need a function that fades down the volume of the flv.
Second you need a second function which checks at which the position the flv is and checks back with the totaltime - 4 seconds of it, therefore you need to create a setInterval that checks every xxxms if the playhead reached the desired position and if yes, it should run the first function.

function fadeOut(){
//your fading code;
}

function timerCheck(){
if(FLVPlayback.playHeadTime > FLVPlayback.totalTime-4){
fadeOut();
}

setInterval(timerCheck, 100);

That should work out
