VideoDisplay playing flv with sound but no picture...

Question

Hi Everyone,
I'm hoping someone can help with an annoying problem that
isn't making much sense to me.... I have an mxml component that is
based on an HBox, which houses a single Video Display control. In
the main application file I add this component which houses the
Video Display control to a canvas using addChild. What I then do is
I play different flv files by containing each flv file name in an
array, and then bind the next flv name to the source of the Video
Display control in order to play the correct video... so in other
words...
<!---------------------------------------------------------------------->
<mx:Script>
<![CDATA[
[Bindable] private var _arrFLVs:Array = new Array("vid1.flv",
"vid2.flv", "vid3.flv");
[Bindable] private var _currentFLV:String;
[Bindable] private var _i:int;
public function init():void
_currentFLV = _arrFLVs[_i];
]]>
</mx:Script>
<mx:VideoDisplay width="398" height="282"
id="videoDisplay" autoPlay="true" source="flvs/{_currentFLV}" />
<!----------------------------------------------------------------------->
I have other functions which increment the _i variable. So
basically what happens is when the video has finished playing, an
event handler executes which is listening for the end of the video,
the event handler then executes another function which removes the
component with the video player from the canvas and adds a
different component to display a series of images, once the images
has finished cycling through what it needs to cycle through I
remove that image component and add the video component back onto
the canvas to display the next flv. This process repeats itself
once all videos has been shown and then starts over again. The
problem I'm experiencing is that every now and then when the video
is supposed to be played, it gets added successfully to the canvas
using addChild, the correct source gets assigned to the video
player, but i see no image when it starts playing. I hear sound,
but no picture. I know the correct source is being assigned to the
video player because I trace it before and while its playing the
video, aside from tracing the source, i hear the audio of the flv
currently playing so i know its the correct flv - only problem is
that there is no picture. The picture not displaying happens
randomly, so for example if the first 4 flv's have finished playing
the 5th won't show a picture although i hear the sound, then the
6th will work fine. When the entire process begins again, the 5th
will work fine, but the 6th and 7th flv won't. This is what totally
confuses me.
What I don't understand is if the correct source has been
assigned to the video display control and the correct flv starts
playing, why do i hear sound but no picture?
Could this be some sort of bug in the flash player? I'm using
Adobe Flash Player 9,0,28,0.
If anyone can provide me with some advice/opinions/idea to
give me some sort of clue that would be grand :).
Thanks for your time,
- Tony

Answer 1

I had this problem before. I found that if the VideoDisplay
component had not finished all inititialization functions before I
assigned the new flv, then I got sound with no video. Try listening
for creationComplete for your VideoDisplay component before you
assign the video source to see if that solves your problem.
