Hi,
I need to replace the specific pcode of a method inside my swf in an autonomous way.
I am aware this is already possible with the -replace command.
The problem with this approach in my case is that there are multiple versions of my swf
which I need to patch and I can't know the method index id beforehand. I do, however, know
the name of the method. Could you please add method name as an option for the -replace
command or provide a way to get that method index id using command line ?
Thanks,
Arthur
You can export your target swf as a p-code.
Making edits on your method.
Then, inject the script back and re-render a new swf.
In an autonomous way, it would be like
----------------------
// export all scripts as P-code
java -jar ffdec.jar -format script:pcode -export script /source target.swf
// processing source file. In this case, inject your p-code with your script and save it
cat /source/scripts/some-class.pcode | some-text-processing-script.sh >
/source/scripts/some-class.pcode
// inject exported modified scripts back to the original swf
java -jar ffdec.jar -importScript target.swf out.swf /source
----------------------
In order to use -importScript, you have to let JPEXS know where the Flex SDK path is.
Flex SDK can be download on Adobe site http://www.adobe.com/devnet/flex/flex-sdk-download.html
Download and extract.
Then, launch JPEX. Go to "Settings" -> "Advanced Settings" -> "Paths" -> on "4) Flex SDK
directory path" point it to your flex sdk directory
Thanks for this method but it had lots of constraints in my case :(.
I forked the sources and edited the "-replace" command to suit my needs. If anyone ends up
