I've run a few more tests, and setting the background color of the ViewNavigatorApplication tag to red, still shows red even though the background alpha is 0. This is all very confusing in Flex, and Adobe really needs to post an example on how to use this in Flex. In theory it should work. Any other ideas?

Hi,

The ViewNavigatorApplication tag for the mobile Flex app does not support that property, so as a test I changed the tags to just Application, which does support that property, and set it to 0. Got the same issue; hear sound, but see no video. Here is the code for the application:

<?xml version="1.0" encoding="utf-8"?>

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

                                                                      xmlns:s="library://ns.adobe.com/fl ex/spark"

                                                                      contentBackgroundAlpha="0"

                                                                      backgroundAlpha="0"

                                                                      creationComplete="init()">

          <fx:Declarations>

                    <!-- Place non-visual elements (e.g., services, value objects) here -->

          </fx:Declarations>

          <fx:Script>

                    <![CDATA[

                              private var mediaPlayer:CatVideoPlayer;

                              private function init():void

                              {

                                        var videoFile:File = File.applicationDirectory.resolvePath("auger_1.mp4");

                                        var videoPath:String = new File(new File(videoFile.url).nativePath).url;

                                        mediaPlayer = new CatVideoPlayer();

                                        mediaPlayer.width = 640;

                                        mediaPlayer.height = 360;

                                        addElement(mediaPlayer);

                                        mediaPlayer.source = videoPath;

                              }

                    ]]>

          </fx:Script>

</s:Application>
