Edição de Vídeo c/ Mencoder

[cebaldocchi]

Pessoal, sempre edito vídeos com o Mencoder, geralmente uso ele só pra diminuir o tamanho do vídeo e funciona bem.

No ubuntu 13.10 o comando tava funcionando... inclusive no meu notebook com Lubuntu o comando ainda está rodando.
Mas nos meus Ubuntus 14.04 LTS nada de funcionar:

#mencoder hookah.mov -ovc lavc -lavcopts vcodec=mpeg4 -vf scale=1200:676 -oac mp3lame -o output.avi
