Workers in AIR for desktop

Question

My question here specific to AIR apps for desktop, not for the web. I have Flex 4.6 and AIR 3.5. I've beed Googling for days with no joy.
There are no code errors but does anyone know where and how to initialize workers in the main mxml file or hat appliaction handler should be used to get the worker thread to set the mainToWorker and workerToMain MessageChannel's, as there is no class initializer like there is in web flex projects.
if(Worker.current.isPrimordial){
                                                  worker = WorkerDomain.current.createWorker(this.loaderInfo.bytes);
                                                  mainToWorker = Worker.current.createMessageChannel(worker);
                                                  workerToMain = worker.createMessageChannel(Worker.current);
                                                  worker.setSharedProperty("mainToWorker", mainToWorker);
                                                  worker.setSharedProperty("workerToMain", workerToMain);
                                                  workerToMain.addEventListener(Event.CHANNEL_MESSAGE, onWorkerToMain);
                                                  worker.start();
                                        }else{
     // if in worker thread
                                                  mainToWorker = Worker.current.getSharedProperty("mainToWorker");
                                                  workerToMain = Worker.current.getSharedProperty("workerToMain");
                                                  mainToWorker.addEventListener(Event.CHANNEL_MESSAGE, onMainToWorker);

1.Make sure you understand the big differences between video and stagevideo, its tempting to think that stagevideo is the better videosoultion in any case, but its not.
The best Article (however a little outdated) on the subject is imo: http://www.adobe.com/devnet/flashplayer/articles/stage_video.html
2.In a performance heavy environment the combination stageVideo+greensock might not be the optimal solution, if you have time to reprogram Starling/feathers will probably give you a much better performing combination:

3.I don`t know how you encode your Backgroundvideo, there are literally dozens of viable codecs that should differ extremly in how they stress the gpu/cpu. Maybe you have to experiment with a lower than HD resoultion and see if scaling up the background is a good compromise.
