FForward and Reverse

I am using this code for my ff and rev buttons. I don’t like them but its all I have for now. I know there is a better way. If I press the ff button the video needs to advance by 1-2 seconds. If the user press the revers button it need to do the same but move back 1-2 seconds. I am using the FLVPlayer Component so doing ns.seek will not work.

my current code

rewind_btn.onRelease = function (){
    myPlayer.playheadTime = 0;
forward_btn.onPress = function (){
    myPlayer.playheadTime = myPlayer.totalTime-1; }

any help would be appreciated
