Question

Running into strange behaviour with flex 3.5. Here is a minimal code:
build.xml target:

<target name="player">
        <mxmlc
            file="${APP_ROOT}/player.mxml"
            output="${APP_ROOT}/player_old.swf"
            keep-generated-actionscript="false"
            static-link-runtime-shared-libraries="true"
            debug="false">
            <load-config filename="${FLEX_HOME}/frameworks/flex-config.xml"/>
            <source-path path-element="${FLEX_HOME}/frameworks"/>
            <compiler.library-path dir="${APP_ROOT}" append="true">
                <include name="lib"/>
            </compiler.library-path>
        </mxmlc>
</target>

player.mxml:

<?xml version="1.0"?>
<PlayerApp
xmlns="*"
xmlns:fx="http://www.adobe.com/2006/mxml">
</PlayerApp>

PlayerApp.as:

package {
import flash.display.Sprite;
import flash.media.Video;
import flash.events.*;

    public class PlayerApp extends Sprite {
        public function PlayerApp() {
            this.loaderInfo.addEventListener(flash.events.Event.INIT, init);
        }

        private function init(e:Event):void {
            this.addChild(new Video());
            trace("loaderInfo: "+root.loaderInfo.width+"x"+root.loaderInfo.height+"\n");
            trace("root stage: "+root.stage.width+"x"+root.stage.height+"\n");
        }
    }
}

the object:

<object width="320" height="240" id="_261178285" name="_261178285" data="player_old.swf" type="application/x-shockwave-flash">
<param name="allowfullscreen" value="true">
<param name="allowscriptaccess" value="always">
<param name="quality" value="high">
<param name="cachebusting" value="true">
<param name="wmode" value="opaque">
<param name="flashvars" value="config={irrelevant}">
</object>

Running all this with a debug player produces the following trace:

loaderInfo: 500x375

root stage: 320x240

This leads to a situation where a Video(contained within a Sprite) added to the app is only displayed as 250×154 or so in size as the 500×375 is squeezed into the 320×240 element it is contained within on the page.

Onward to the question: Is it possible to avoid this bug in any way so that the swf will still work with flash version 9.0.115. I also would rather not hard-code the size in the build.xml file, as the player size could change in the near term future.

Disclaimer: I’m using flex 3.5 as flash player 9.0.115 must be supported AND flash 9.0.115 must be supported because of corporate customers (Even 9.0.115 seems to be too much asked for some.) I also noticed I can compile the .as without the .mxml, but I left it here as is.

Answer 1

Have a look at Stage.scaleMode resp. the scaleproperty on object/embed tags.
