[MPlayer-users] mencoder to convert PNGs to flv

[Blaine DaRonco]

I'm trying to convert a directory of PNGs into a flash video.  I'm  
using the following command which I think should work:

mencoder -mf type=png:fps=5 mf://*.png -forceidx -of lavf -oac mp3lame  
-lameopts abr:br=56 -srate 22050 -ovc lavc -lavcopts  
vcodec=flv:vbitrate=250:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -o  
video.flv

But I'm getting the output below when I run it on a server.  I've  
tried with and without the mp3 options.  I don't really know what to  
make of the error I'm getting.  Is there possibly something wrong with  
the configuration on the server I'm running on?  Any help would be  
greatly appreciated.
