[Platform_iOS]StageVideo makes stage opaque to Stage3D


Problem Description:
When using StageVideo (or even adding a listener for StageVideoAvailabilityEvent.STAGE_VIDEO_AVAILABILITY -- either one will cause this problem), display objects on the stage become opaque in front of the Stage3D layer.

Steps to Reproduce:
Add an event listener like this at any point in the program -- you can even remove it immediately and get the problem:


theStage.addEventListener(StageVideoAvailabilityEvent.STAGE_VIDEO_AVAILABILITY, nothing);
theStage.removeEventListener(StageVideoAvailabilityEvent.STAGE_VIDEO_AVAILABILITY, nothing);

private function nothing(event:StageVideoAvailabilityEvent):void

Now put content on the stage3D layer, as well as the classic stage. (For instance, I add a simple shape:
var newCircle:Shape = new Shape();;,384,100);;

You will also get this without the event listener, but when getting a StageVideo object. The problem persists after the StageVideo object has been cleaned up, to the best of my ability.
m_stageVideo = m_instance.stage.stageVideos[0]; // this line makes subsequent stage3D not show up behind stage.
m_stageVideo.addEventListener(StageVideoEvent.RENDER_STATE, stageVideoStateChange);
m_stageVideo.viewPort = new Rectangle(0, 0, Global.SCREEN_WIDTH, Global.SCREEN_HEIGHT);

Actual Result:

The bounding box around this shape will be black, but it should be transparent. It works on the PC emulator but not the iPad.

Expected Result:

Transparent pixels on the stage should show the Stage3D layer underneath it. (It works if you don't add the event listener above, or use StageVideo.)

Any Workarounds:
Don't use StageVideo, or don't use the Stage, or don't use Stage3D.

    Try to use VideoTexture :) It's new feature of Adobe AIR

    Hi, I found a solution for avoiding this bug.
    The transparency is dysfunctionning when you close the Netstream connection. Never close the ns, just play a blank video (black screen and no sound) when you play the 3D scene.

    That was the good solution for me.

    I don't think it's hardware issue because my work around is working before...

    Here's how
    1. attach stream and play game intro video with StageVideo
    2. when done intro do attach stream to normal Video (this is a trick)
    3. dispose all video related as usual

    now start Stage3D for game play

    bad news this workaround is stop working after AIR 3.5 as i recall
    and comment here is really mislead to

    "I can't use Stage3D and StageVideo together at the same time"

    which is not the point and too fancy, actual problem is...

    "I can't use StageVideo then dispose it and then use Stage3D later"

    (which is previously doable before AIR 3.5 but not anymore as i said)
    and result for this mislead is Adobe think it's same issue and then close both issue just like that.

    Workaround today is keep StageVideo in memory like zombie...why? because "The problem persists after the StageVideo object has been cleaned up"

    Trouble is friend of us ;p

  • Anton Azarov

    3:50:40 AM GMT+00:00 Feb 19, 2014

    iPad can't play transparent video using own controls. So removing black area it's CPU job. iPad as all devices use weak CPU.
    For this reason you can't use Video Texture in Unity3D.

    It's technically impossible. Or if you can do this - next question will be "Why is so slow??"

  • ThreeRoll

    9:59:05 AM GMT+00:00 Dec 11, 2013

    Would it be possible for Adobe to provide a more complete explanation of the issue and how it is as designed? It also seems like additional guidance on how to get StageVideo and the Flash display list to coexist would be helpful to a lot of people.

  • Anton Azarov

    10:07:30 PM GMT+00:00 Dec 10, 2013

    I think it's not as designed. It's hardware limitation.

    Well, I've tried to use Context3D.present() and it doesn't fix anything, unfortunately.

  • rockdeman

    7:13:15 AM GMT+00:00 Oct 30, 2013

    Is there any hope that it will ever be possible to add Stage3D content over StageVideo? It would allow fantastic Smart TV GUIs.

  • Hitomi Kudo

    11:57:51 AM GMT+00:00 May 21, 2013

    And our developer confirmed this as expected behavior = AsDesigned:

    "correct, this is not a bug. When using Stage3D, the user must call Context3D.present() to make the stage layer update. There is no independant update of the Stage, Context3D.present() drives the update of both the Stage and the Stage3D layers. This is necessary to achieve high performance. Workarounds include making all the Stage3D invisible and delaying the Context3D creation until you are going to start using it."

  • Hitomi Kudo

    11:56:25 AM GMT+00:00 May 21, 2013

    I found this note in internal bug comment that it may help you:

    The problem is not due to stage video. It is due to the way in which 'direct' mode works. This mode uses context3d.present() to submit the changes in 2D stage to screen.

    After making changes to the display list ( for eg. stage.addChild(newCircle)), the user should call context3d.present (). Otherwise he will get this behavior. Consider the following code to reproduce the issue without any stageVideo.

    package {

    public class main extends MovieClip {

    private var context3D:Context3D;
    private var xpos:Number = 150;
    private var ypos:Number = 150;
    private var newCircle:Shape;
    private var Num:int = 0;

    public function main(){
    this.newCircle = new Shape();
    super();;, this.ypos, 20);;
    stage.stage3Ds[0].addEventListener(Event.CONTEXT3D_CREATE, this.onContext3DCreate);
    private function onContext3DCreate(_arg1:Event):void{
    var _local2:Stage3D = ( as Stage3D);
    this.context3D = _local2.context3D;
    if (this.context3D == null){
    _local2.x = 100;
    _local2.y = 100;
    this.context3D.configureBackBuffer(240, 180, 0, false);
    addEventListener(Event.ENTER_FRAME, this.onEnterFrame);
    protected function onEnterFrame(_arg1:Event):void{
    if (this.Num < 1){
    this.context3D.clear(1, 0, 0);
    this.Num = (this.Num + 1);



    1. During configureBackBuffer, player marks the stage3Ds[0]'s viewport for punching alpha hole . (Color(0,0,0,0))
    2.Immediately , player calls onEnterFrame and context3d.present(). It also blits the circle with opaque border to screen.
    3. Then player does the DoPlay_UpdateSceen(), where the alpha hole is created in the 2d stage canvas. The circle will be re-drawn with transparent border.

    Since there are no further context3d.present() calls, the updated 2d stage canvas (with transparent border) is not drawn to the screen. If we modify the condition (this.Num < 1) to (this.Num < 2), the updated canvas will be drawn on screen without any black border. I feel, the whole thing is a behavior of 'direct mode' and not a bug.

    A similar problem with StageVideo happens in Android. I've filed a separate bug report for Android here:

  • web_job

    2:11:35 PM GMT+00:00 Mar 20, 2013

    I have also come to this problem. It's absolutely ridiculous that this issue is not fix almost after the year of been reported.

    Just to add a bit to description. It seems that the issue occurs when you use all 3 components: stagevideo, stage3d and displaylist. The issue occurs right after you access some of the stagevideo properties. Even setting the StageVideoAvailabilityEvent.STAGE_VIDEO_AVAILABILITY triggers it (though the handler does not have any code). Also, the issue occurs only when you do not successfully stream video (or dispose stream after playing).

    1) Request Stage3D
    2) Create StageVideo
    3) After StageVideo ends - Stage3D is black because StageVideo have fully black fills

    As I look at my screenshot I see a small red dot that is part of the map texture -- the big red circle in the middle shows the problem.

    Also, I'm developing on a Mac.

    I'm submitting an example screenshot from my iPad1. I'm using the Away3D engine to display the globe but the same thing happens with Alternative or Starling, or our internal Starling-inspired 2D Molehill renderer. The red circle is a shape on the stage and is the only content there.

    Is this Adobe's way of dealing with critical bugs?! Just assign it as 'by design' and forget about it? I can't believe this hasn't been dealt many others on this page state this is still an issue and the 'workarounds' don't work with Android devices , i.e. the context3d.present() does nothing (although Adobe state that's the fix and the excuse for placing this bug as 'as designed' . Neither do the hacky work-arounds of not disposing of the Netstream object (though this may work on iOS I haven't tried that yet as I'm building an android app)

    Adobe - could you respond to the concerns on this bug please?

  • reinier_77

    12:48:23 AM GMT+00:00 Nov 26, 2014

    Mobile devices need StageVideo for smooth video playback and Stage3D for optimal game performance. This affects our app on both iOS and Android but is not an issue on desktop. For iOS there is a workaround (never detach or dispose NetStream) but unfortunately this does not work for Android. HIGH PRIORITY!

    Due this problem we had to refactor our application. After a week of searching and trying to figure out what the problem was, we had to use a not so nice solution to work with video and stage3d together. Would be a great winner if this is going to be fixed!

    Tried a number of workarounds (pausing instead of detaching netstreams, moving the video viewport off the screen, delaying creation of the context3d until after the video) and none of them have worked on iPads 2nd-4th gen. Which is quite a bummer, as stage video plays back so much better on these devices compared to software mode.

    We're having the exact same problem in iOS. We've lost countless hours troubleshooting this problem before concluding it was caused because of StageVideo. Also, since our application uses a lot of video, we can't just stop using videos to avoid this Stage3D bug.

    Stage3D and StageVideo are important AIR/Flash technologies, and shouldn't interfere with each other. This should be fixed ASAP. Please do not wait another year to fix this.

    Not having this capability is a deal breaker for me. The world of social video interaction is becoming hugely popular. Without the use of both stage 3d and stage video performance will continue to be an issue for rich experiences on IOS. The framework is unstoppable if you can allow these two technologies to work in harmony.

    Thanks for your consideration :)
