Deploy application on Linux

Question

     Hello,
I'm currently deploying an Air application on a Ubuntu distribution and the behaviour of this application slightly differs from its behaviour on Windows.
On most of the problems, I could find a solution but it remains two issues I can't fix.
First one, the load function for MP3. When I load a MP3 in order to get the metadata especially the length of the mp3, my Windows app succeed but in ubuntu, the load is never dne, and even the complete event of the load never launched.
Second one, the camera. I attach a webcam to a videodisplay and visualize it on my screen. In Windows, i can put my video up to 1600x1200 in resolution but in Ubuntu, the same code doesn't allow me to get a resolution better than 320x240. WHen I force it to a 640x480, the image stills stand in a ugly 320x240 pixels.
What can I do to avoid these deploying issue.
I m working witth flash builder with flex 4.0 and AIR 2.0.
My ubuntu is 9.1 with a linux kernel 2.6.31.
Thanks in advance for those who have an answer.
Regards
Julien

Answer 1

First thanks for the replies,
as you said that it works for you, I figure out that my problems came from my implementation, but still can't figure out where it is.
I simplified my code in order to post it clearly:
<?xml version="1.0" encoding="utf-8"?>
<s:Group xmlns:fx="http://ns.adobe.com/mxml/2009"
                 xmlns:s="library://ns.adobe.com/flex/spark"
                 xmlns:mx="library://ns.adobe.com/flex/mx" width="400" height="300">
        <fx:Script>
                <![CDATA[
                        import mx.controls.Alert;
                        import mx.events.ListEvent;
                        [Bindable]
                        public var mp3Directory:File=new File(File.documentsDirectory.url+"/Briche/MP3");
                        public var mp3:Sound;
                        protected function MP3_changeHandler():void
                                mp3=new Sound();
                                mp3.addEventListener(Event.COMPLETE, id3Handler);
                                Alert.show(MP.selectedPath,"MP3");
                                mp3.load(new URLRequest(MP.selectedPath));
                                // TODO Auto-generated method stub
                        //getting the meta data from the mp3
                        private function id3Handler(event:Event):void
                                var length:Number=mp3.length/1000;
                                Alert.show(mp3.url,length.toString());
                ]]>
        </fx:Script>
        <fx:Declarations>
        </fx:Declarations>
        <mx:FileSystemTree id="MP"
                                           width="180" height="400"
                                           directory="{mp3Directory}"
                                           enumerationMode="filesAndDirectories"
                                           extensions="[mp3]"
                                           borderAlpha="0"
                                           dragEnabled="true"
                                           dragMoveEnabled="true"
                                           change="MP3_changeHandler()"/>
</s:Group>
So when I try this code on linux, I can do some stuff. If I try to load an mp3 I join with my application
and which is present in /opt/.../share/, it succeeds. But if I try another mp3 located anywhere else on my computer, it fails.
Here is where I am in my problem.
