swf2mp3 in Linux?

[Hart Larry]

Hi All:  More-and-more I am finding media which is in a flash swf format.  Just 
the other day I actually downloaded a 9mb file of a 1948 Humphrey Civil Rights 
speech, however, so far an only way we could play it was to go in x--and use an 
actual Adobe player.  From the console we tried many options with gnash  with 
no luck.
I ran google searches for swf2mp3 as well as flash2mp3  but only found windows 
software.
Ultimately, sure it would be nice to play these files, but would be even 
greater to convert to either an audio format, or .mp4 if its really video.
Can some1 please inform if there are Linux software for this--and-thanks in 
advance
Hart
