[MPlayer-users] thumbnail from a SWF / VP6

[junk]

i'm using mplayer on fedora core 5.  i have SWF videos, encoded in VP6.

mplayer someVideo.swf -ss 60 -frames 2 -vo jpeg

i take 2 frames because the first one is always the first frame of the 
video, the second is the desired frame at the specified seek time.

however, the output of the second frame is always scrambled, seems it 
has been processed incorrectly.

the SWFs are encoded in VP6 .  as far as i can see, mplayer has a VP6 
decoder, so i'm not sure why this is happening.  is there something i'm 
missing?

any help is appreciated, thanks.
