Flash File Format SDK question
|
|
| Michael D. Randolph 2005-05-05, 5:45 pm |
| This isn't really an FCS issue, but does anyone know of any way to check
if a SWF has code in it? We want to let customers uploads SWFs to our
site to use in an application...but we don't want there to be any code
in them. I don't think there is a boxed solution that will do this, but
does anyone know if it's possible to write a C++ app that will check a
SWF for code using the file format sdk?

Might be able to use swfmill and see if there any script blocks in the
..xml file. I have no idea what the XML produced by swfmill looks like
(haven't ever used it yet), so this might not work..
http://iterative.org/swfmill/
Also, you can try using JavaSWF, it should enable you to parse files:
http://sourceforge.net/projects/javaswf/
Or, you can run flasm ( http://flasm.sourceforge.net/ ) on the .swf and
see if theres anything in the .flm file.
Probably other options too, but this should get you started.

Just tried it, if you run flasm on a .swf with no code in it, the
resulting .flm file (in my test anyway), only had 3 lines -
movie { path and information here on the same line }
end
... with a blank line following end.
So, I think can you check "line 2" to see if it's "end" or not. In .flm
files of .swf files that had code in them, line 2 was always blank. *shrug*

| I'd like to automate this as a server process whenever someone uploads a
swf. Our application is written in ASP.NET. I suppose with enough work
I could make flasm work...any other ideas?
