Converting .fla or .swf to gif (Command prompt / Action script / Flex)

I'm currently looking for a solution to convert any .fla or .swf file into a .gif without using the basic "File > Export to ..." (This i开发者_运维知识库s for a pretty large amount of files)

I can use any of the following languages : Action Script, Flex or even the windows command prompt. I already had a look at http://www.swftools.org/about.html but there's only a GIF2SWF, and not a SWF2GIF.

Anyway, if anyone know a possible way to do this, thanks in advance !
