My Full Screen Video App – Ver 1.0

I wrote about full screen support in flash, a long time back in Nov ’06 (see that post here). I have been planning to write one myself. So finally i got myself down to write it. Before i put you through the app, some details on the API.

To make your application have a fullscreen support you need to do the following things.

1) Have the latest Flash Player (get it here)

2) Use the new Full Screen API
import flash.display.StageDisplayState into your Application and set the displayState of the stage. I have the following function toggling the FullScreen feature. “fsChk” is a CheckBox, based on which I’m toggling the functionality

private function toggleFullScreen():void{

stage.addEventListener(FullScreenEvent.FULL_SCREEN, handleFullScreen);

if(fsChk.selected) {
stage.displayState = StageDisplayState.FULL_SCREEN}
else {
stage.displayState = StageDisplayState.NORMAL}


3) Update the html-template in which you have the flash App

In the object & embed parts of the html code of the page in which the flash app is inserted, you need to add a new parameter allowFullScreen to true. You can refer the source of the app and view the html for details.

If you want to know more about this feature, refer the Adobe DevCenter article on the same or view the PDF that i have created, collating all that information.

Now the Application. This is just a small video player which can go full screen by checking a Flex CheckBox. This is written in Flex2.0 and you can find all the source files here

Click here to view the Application
(confirm that you have the latest Flash player)

P.S – I have muted the video to start with, un-mute it if it pleases you 🙂

Update March 07 2008: A lot of people have complained that they got a security error when they tried using the code above. Here is a post articulating the problem and the solution.

    Hey there,

    Thanks for the info, but I’m getting nothing from this link:

    Hi Ken,

    I tried it on my mac and it works. I have a MAC 10.4.8 with Firefox

    Looks like the player detection code is not properly put in… See if you have the latest player. If it still persists, drop me a mail at “rrao at adobe dot com”

  3. Raghu says:

    I’ll try to put my player detection code in palce by then 🙂

    To solve the problem you can use the applicationComplete event instead of creationComplete.

  11. raghunathrao says:

    You require Flash player (9,0,115,0) for full screen to work

  12. Ajay says:

    i tried the above full screen example…but the screen is getting full screen but the size of the player remains the same…can u help?

  13. Ajay says:

    Hi Raghu,

    does the code u wrote for full screen supports flex2?

  14. Ajay says:

    i dont want the panel and videodisplay width and height to be 100%. if both are in numbers like width =400, height=400 for panel and full screen will the full screen function work?

  15. raghunathrao says:

    @ Ajay – I think it works in Flex 2 too, but you need the right player to run it

    myVD.playheadTime = myHS.value;


    private function muteOnOff():void{
    if(mute.selected){myVD.volume = 0; }
    else {myVD.volume = 0.75}

    private function loadVideo():void{
    myHS.maximum =myVD.totalTime;

    private function toggleFullScreen():void{
    stage.addEventListener(FullScreenEvent.FULL_SCREEN, handleFullScreen);
    if(fsChk.selected) {stage.displayState = StageDisplayState.FULL_SCREEN}
    else {stage.displayState = StageDisplayState.NORMAL}
    private function thumbPressed():void{
    pauseFlag = true;
    playpause.label = “>”;

    it would help me alot
    i need to know how to make full screen work on a webpage.

  18. Lele says:

    just wanted to say thank you for such and awesome post and for providing all the support and code to make this happen … Im still learning Flex and this has been invaluable to me!

    Many Thanks again! 🙂

  19. Sangeeth says:

    Thanks Raghu for the post.

    And for those who are getting the security error display, just add this code in four places in index.template.html in the html-template folder. This works for me


    So the wrapper html will be like this :

    “src”, “playerProductInstall”,
    “FlashVars”, “MMredirectURL=”+MMredirectURL+’&MMplayerType=’+MMPlayerType+’&MMdoctitle=’+MMdoctitle+””,
    “width”, “${width}”,
    “height”, “${height}”,
    “align”, “middle”,
    “id”, “${application}”,
    “quality”, “high”,
    “bgcolor”, “${bgcolor}”,
    “name”, “${application}”,
    “type”, “application/x-shockwave-flash”,
    “pluginspage”, “”
    } else if (hasRequestedVersion) {
    // if we’ve detected an acceptable version
    // embed the Flash Content SWF when all tests are passed
    “src”, “${swf}”,
    “width”, “${width}”,
    “height”, “${height}”,
    “align”, “middle”,
    “id”, “${application}”,
    “quality”, “high”,
    “bgcolor”, “${bgcolor}”,
    “name”, “${application}”,
    “type”, “application/x-shockwave-flash”,
    “pluginspage”, “”
    } else { // flash is too old or we can’t detect the plugin
    var alternateContent = ‘Alternate HTML content should be placed here. ‘
    + ‘This content requires the Adobe Flash Player. ‘
    + ‘Get Flash‘;
    document.write(alternateContent); // insert non-flash content
    // –>
