ActionScript 3.0 provides for a way to determine if a swf is for either: 1) AVM2 (or earlier); or 2) AVM3. [link1, link2]My Question:From C#, is there a way to determine if a swf is for AVM1 or AVM2?
View 2 RepliesLet's say we have a directory with 10,000 SWF files.There is a great need to determine what SWF files are AVM1 (AS2 or earlier), and what SWF files are AVM2 (AS3).Can anyone point me in the right direction to determine the AVM version for a large amount of files?It seems like I could write a script that loops through every file, checks some magic hex value in the file's binary data, and records the result somewhere.

I have a large project built in as3. Part of its main functionality is to load and unload various as2 swfs. The problem is that the memory ins't free up once they are unloaded.
I have access to the as2 swfs code base and destroyed all objects, stopped and killed timers, listeners, removed from stage, destroyed all the MovieClip.protoypes that were created. They look to be clean as far as the AS2 debugger show no remnants of the object after the destroy function is run. In AS3 i've closed the local connection, cleaned all references/listeners to the AVM1Movie and ran Loader.unloadAndStop(). The trace out in flex says the swf was unloaded but looking at windows task manager the memory usage never drops to when it was before the as2 swf was loaded. Each as2 swf can take up to 80 megs each time it's run so memory gets eaten up fast and loading and unloading a few as2 files.
At this point if the AS2 swfs are unloaded the only thing that I can assume that could be left is MovieClip.prototype and/or _global, _root variables add during the AS2's run time. But i've gone through those and can't find anything else that might be sticking. Has anyone ever seen problems before with the AVM1 machine not freeing up its memory?
I've been playing around with ABC bytecode and was hoping someone could clear up a point of confusion for me. I have a simple flash file that places a clip on the stage and has a tiny script to update its position on each frame. The code looks something like:

My question is how does the 'getlex' operation work (I've marked it with ###1). It is passed a multiname which references the 'moveit' method of the class. Unfortunately, the 'name' field in method info seems never ever to get used by the compiler. All methods have the empty string as its name (Shown above as the unnamed function at ###2).
How does the flash player link the multiname to the unnamed method? There appears to be no provision for this in the AVM2 spec. I know it's possible because commercial decompilers like sothink manage to determine the method name. I'm just not sure how they do it, or how the code could ever work.
Im working on a banner testing application coded in flashdevelop on Adobe Air 1.5, testing sizes, kb, animation time etc. One of the tests ran by the application is clickthroughs via clicktags. Since most of these banners are coded in AS2, I�m injecting the variables via querystring when loading the banners swf files (via a browse/drag drop File reference).
PHP Code:
var req:URLRequest = new URLRequest("banner300x250.swf?clickTag=hello");
This works fine for _root references to clicktags, but when the banner is looking for the variable in _level0 I just can�t figure out how to write these variables.I've tried to load a bridge AS2 movie and set the variables there, something like AVM2 localConnection --> AVM1 localConnection --> AVM1 banner, wich worked fine on flash IDE testings, reading all _level0 on the AVM1 bridge, but compiled on Air became into a security errors storm and undefined values for _level0.
I have a AS2 header that loads some obnoxious sound on the initial load. I created a simple AS3 container that loads and mutes the sound - which works as expected. However, now the displayed swf is smaller than the original. Basically all I am wanting to do is mute the original without changing any of the dimensions.here is the code in question:

Currently I'm working on a flash application that will be used for presentation purpose. The application loads external swf files which are exported from powerpoint. This way people can make there own powerpoint presentation, export with a plugin as swf files included with animations, video or audio.
The presentation itself is a 3D carousel containing icons which represent chapters. Once a chapter is clicked, a page slider opens and loads all external swf files needed for that chapter.When someone is done with that chapter, you can close the pageslider. To make sure the application keeps it performance, it will remove all event listeners, free display objects hold in arrays and get rid of all what won't be used again. This works fine, the memory use goes back to original state and no problem.
Now when I take a closer look at the fps of the application which is set to 60fps, and load AVM2 content, nothing goes wrong whatever I do or close. As soon as I load AVM1 content and display it, the fps stays steady at 60. But as soon I close the pageslider and free up memory, the fps is stuck at 30. As soon I open a chapter with another AVM1 content, the fps restores to 60.Now I thought maybe it's because I did something wrong when I free some memory, so I turned that function off which gets rid of all the stuff. Then I tried again, but again when I load AVM1 content I got 60fps but when I don't display the content my fps goes back to 30. But this problem doesn't exist when I load AVM2 content or even just png's instead of swf files.But when I turn this free memory function on and not display the AVM1 content and which doesn't exists at all on the background anymore, the fps is still 30.
Now I thought about a fix to just restore the framerate afther the pageslider is closed. But as soon I use "stage.frameRate=60" the player crashes completely. how can AVM1 content on display let the application run 60fps, but when removed from memory and not displayed set the fps to 30 and get to 60 again as soon new AVM1 content is displayed? But AVM2 content it's all just fine.
The reason I load AVM1 content is because the powerpoint -> swf exporter can only export AVM1 content.I also checked if the fps of the exported swf is set to maybe 30, but that's not the issue, and besides that it theoretically would use the main swf it's fps.I could set the main application fps to 30 and no one would notice, but I just can't sleep why i can't figure out the issue.Btw when I set the main fps to 30 it won't be reduced to 15fps.
Does anyone know a good way to convert AVM1Movie objects to AVM2?

what exactly happens in the graphics-object? I assume that it will be calls to a rendering API of the AVM2, but how does this look like? Is there any way to look at it, or are these sources completely closed for anyone outside of Adobe?
I've seen the Loom project, but are there any alternatives that are more mature (and actively developed)? I am looking for something that would allow load-time weaving of pointcuts into existing binary code at runtime with the AVM2 runtime.
Has any work been done in this area?
