I am using FlashBuilder to create flash file to show streaming video. Please see the following code:
<?xml version="1.0" encoding="utf-8"?>
xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="1280" minHeight="720">
<!-- Place non-visual elements here, for example, services and value objects -->
import org.osmf.net.StreamingURLResource; import org.osmf.net.FMSURL;
protected function vp_preinitializeHandler(event:FlexEvent): void
var myURL:StreamingURLResource = new StreamingURLResource("http://www.sample-videos.com/video/mp4/720/big_buck_bunny_720p_1mb.mp4");
myURL.urlIncludesFMSApplicationInstance = true;
myVideoPlayer.source = myURL;
<s:VideoPlayer id="myVideoPlayer" autoPlay="true" preinitialize="vp_preinitializeHandler(event)" x="2" y="2" height="100%" width="100%" />
After I click Menu >> Project >> "Export Release Build", FlashBuilder generates a swf file, which looks fine. However, I found that the swf file changed EVEN IF I did not change any code. In other words, the same code generates different swf files in each "Export Release Build" click. I used command line fc to compare the generated swf files and confirmed each file is different.
I installed FlashBuilder of the newest version (ver 4.7 from Adobe). I wonder why the same code generates different swf files, and what kind of information is included in those different swf files.
Your help is greatly appreciated.
