I created my own seekbar in the Flash IDE (can be a simple movieclip with 100x10px dimensions). It has a certain widht (variable) and can be clicked on. This is the function to skip to the movie position clicked.
private function controlsSeek():void {
// Get distance in pixels where the mouse is clicked
var mouseGlobalPosition = new Point(mouseX,mouseY);
var mouseLocalPosition = playerControls.seekbar.globalToLocal(mouseGlobalPosition);
// Afstand van de balk vanaf het nulpunt
var pixelsClicked:int = mouseLocalPosition.x;
// Percentage aan de hand van het aantal pixels
var pixelsPercentage:int = (pixelsClicked / playerControls.seekbar.seekbarLoadedBackground.width) * 100;
// Converteer pixels naar het aantal seconden waar de film heen moet
var pixelsToSeconds:int = Math.ceil(pixelsPercentage * (player.getDuration() * 0.01));
player.seekTo(pixelsToSeconds, true);
}
It works for me, if someone has a better solution or idea please throw it at me. If you use this method and it works oké, please let me know also.
