Problem Description

Application crashes on fast application exit with AIR 33 and StageVideo with some videos playback by Windows devices. You can reproduce it via NativeApplication.nativeApplication.exit() or by closing via Alt+F4 just after application start.

It has been tested with latests AIR 33.0.2.338 and AIR 33.1.0.50 with many different Windows devices.
Same problem in all cases with some videos.
I have reproduce it with video file from issue #88

It works fine with AIR 32.0.0.89 and below.
There is no such crash with macOS and AIR 33.1.0.50.
NetStream::useHardwareDecoder=false doesn't help. Video doesn't work at all because of that: #155

Steps to Reproduce

Launch code below with Windows devices.

Application example with sources and example of video attached.
stagevideo_close_crash.zip

package {
	import flash.display.Sprite;
	import flash.events.Event;
	import flash.net.NetConnection;
	import flash.net.NetStream;
	import flash.media.StageVideo;
	import flash.geom.Rectangle;
	import flash.events.NetStatusEvent;
	import flash.desktop.NativeApplication;
	
	public class StageVideoCloseCrash extends Sprite {
		private var nc:NetConnection;
		private var ns:NetStream;
		
		public function StageVideoCloseCrash() {
			addEventListener(Event.ADDED_TO_STAGE, init);
		}
		
		private function init(e:Event):void {
			removeEventListener(Event.ADDED_TO_STAGE, init);
			
			nc = new NetConnection();
			nc.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
			nc.connect(null);
		}
		
		private function netStatusHandler(event:NetStatusEvent):void {
			trace(event.info.code);
			switch (event.info.code){
				case "NetConnection.Connect.Success":
					ns = new NetStream(nc);
					ns.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
					ns.client = {onMetaData:getMeta, onPlayStatus:onPlayStatus};
					var sv:StageVideo = stage.stageVideos[0];
					sv.viewPort = new Rectangle(0,0, 1280, 800);
					sv.attachNetStream(ns);
					ns.play("video.mp4");
					break;
				case "NetStream.Play.StreamNotFound":
					trace("Stream not found");
					break;
				case "NetStream.Buffer.Full":
					NativeApplication.nativeApplication.exit();//This line cause crash. If crash doesn't reproduced then comment this line and close application by Alt+F4 just after start to reproduce it.
					break;
				default:
					break;
			}
		}
		
		private function getMeta(mdata:Object):void { }
		
		private function onPlayStatus(infoObject:Object):void { }
	}
}
