How to convert swf to mp4 / flv or so with the command line?

I am going to convert swf to mp4 / flv or so with a batch line in linux.

I tried ffmpeg , mencoder or perl script FLV :: info . But all this only converts the video in swf (possibly encoded by H.263 or so) into a new video, but without movie clips , without mentioning ActionScripts.

I find moyea seems to fit my needs (however I need linux), but are there any free ways to do this

Many thanks.
