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.
