AIR 15 and iOS StageVideo

To add to this, sometimes local StageVideo does work, but always when it does work the app goes on to crash when the stream is closed. That remains true in AIR 15.

So, I managed to figure out the reasons why StageVideo sometimes wouldn't kick in, and also why when it kick in it would crash on exit.

Sample code online shows to use this:

StageVideoAvailabilityEvent.STAGE_VIDEO_AVAILABILITY

It turns out that in iOS that event may have happened already, before the point where you add the listener. I've changed things to be like this:

if ( stage.stageVideos.length >= 1 ) {

       _enableStageVideo();

  }else{

       _stage.addEventListener(StageVideoAvailabilityEvent.STAGE_VIDEO_AVAILABILITY, _onStageVideoAvailability);

  }

Most times the stage.stageVideos has settled down, and there's no need to listen for the availibility.

The crashing on exit was because you can't do this:

_stagevideo.attachStream(null);

_ns.close(); //etc

you have to do this:

_ns.close(); //etc

_stagevideo.attachStream(null);

So, that just leaves a request here of sample code for the AIR 15 way of working. Under AIR 14 I have all the Video fallback code too, and it would be nice to strip that out.

My bet is that if it transparently uses video if need be, it also transparently gets rid of it when you dispose of stage video.
