SWFVisualizer - SWF File Format Visualization with Flash http://rintarou.dyndns.org/swfvisualizer/ The code is under GPL or another optional commercial license if you prefer. (Contact: shuho.chou@gmail.com) Other sources included in lib/* were under their own licenses. Try it first http://rintarou.dyndns.org/tests/SWFVisualizer.html How to build 1. Install FlashDevelop + Flex 4.0 SDK compiled SWF10 binary 2. Open "SWFVisualizer.as3proj" and run it. Setup for your own services SWFVisualizer should work with my another project(https://github.com/RintarouTW/swfparser). If you want to use swfparser to build your own service, modify Global.as: swf2jsonURL : "http://rintarou.dyndns.org/tests/swf2json.php?swfURL=", uploadswf2jsonURL : "http://rintarou.dyndns.org/tests/uploadswf2json.php", to the URL of your own services. Patch of other source I patched lib/com/adobe/serialization/JSONDecoder.as for ordered key array. If you update the library on your own, remember this patch.
