[flexcoders] I set VideoDisplay.source to a 404, but VideoDisplay simply says it's "loading"

[Yair Flicker]

Hello people,

I have a problem where I set the videoDisplay.source property to an
invalid URL - 404 - call the .play() method, and then the videoDisplay
simply says that it's loading. It doesn't give any indication of an
error, just sits there and says it's loading. It's the most annoying
thing in the world....how the hell am I supposed to know when the
.source property points to an invalid URL?!?!?! I even have a timer in
there to output the state of the VideoDisplay every 2.5 seconds - all it
says is that it's loading. Am I crazy? Am I doing something wrong? Or is
this a blatant bug in Flex?

Try this MXML:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";
<http://www.adobe.com/2006/mxml>  layout="absolute">

<mx:Script>
<![CDATA[
import mx.events.VideoEvent;
private function showInfo(event:VideoEvent):void {
trace('stateChange: ' + event.state + ' ' + event);
var foo:Timer = new Timer(2000, 100);
foo.addEventListener(TimerEvent.TIMER, timerComplete);
foo.start();
}
private function timerComplete(event:TimerEvent):void {
trace('timerComplete: ' + vid.state + ' ' + event);
}
]]>
</mx:Script>

<mx:VideoDisplay id="vid"
source="http://sjc-v90.sjc.you1234tube.com/get_video?video_id=BTh8no91g5\
4E" <http://sjc-v90.sjc.you1234tube.com/get_video?video_id=BTh8no91g54E>
autoPlay="true" width="450" height="338" stateChange="showInfo(event)"
/>

</mx:Application>


The trace debug output is as follows:
stateChange: loading [Event type="stateChange" bubbles=false
cancelable=false eventPhase=2]
timerComplete: loading [TimerEvent type="timer" bubbles=false
cancelable=false eventPhase=2]
timerComplete: loading [TimerEvent type="timer" bubbles=false
cancelable=false eventPhase=2]
................
timerComplete: loading [TimerEvent type="timer" bubbles=false
cancelable=false eventPhase=2]
timerComplete: loading [TimerEvent type="timer" bubbles=false
cancelable=false eventPhase=2]

And btw, if you set the source to
http://chi-v45.chi.youtube.com/get_video?video_id=n4Fwge2iqJ0
<http://chi-v45.chi.youtube.com/get_video?video_id=n4Fwge2iqJ0> 
(another 404), Flex detects it immediately and the trace output is what
you would expect/hope.

Anybody else experience this problems?  Can anybody think of any
fixes/workarounds?  Am I doing something wrong?  Thanks!
