video onended goto beginning

i managed to add 'click to play' poster frame

and made a toggle bit:
scene.onPointerUp = function() {
        if (videoTexture.video.paused === true){
        videoTexture.video.play();
        } else {
        videoTexture.video.pause();    
        }

but now i wonder how to add the eventListener("onended") and set currentTime to 0 again AND show the posterFrame.
Any ideas?
