Después de probar varias opciones para convertir vídeo RMVB a AVI, con el comando mencoder, la única forma que pude convertirlo fue la siguiente:
Primero:
Instalar el repositorio medibuntu de la siguiente forma:
sudo wget http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list --output-document=/etc/apt/sources.list.d/medibuntu.list
sudo apt-get -q update
sudo apt-get --yes -q --allow-unauthenticated install medibuntu-keyring
sudo apt-get -q update
Luego de instalar este repositorio instale los siguientes paquetes:
sudo apt-get install mencoder mplayer librte1 librte-dev non-free-codecs
Por ultimo baje el reproductor Real Player para Linux que baja con extensión bin (RealPlayer11GOLD.bin) al cual hay que darle permisos de ejecucion (chmod 755 RealPlayer11GOLD.bin) y por ultimo en /usr/local/codecs hice un links simbolico desde /opt/real/codecs/ donde se encuentra el archivo drvc.so el cual necesita para convertir el video, sino me probocaba el siguiente error:
csottile@smarcnet:~$ mencoder p-CrossingO778.rmvb -oac mp3lame -lameopts preset=128 -ovc lavc -lavcopts

Una vez echo este link simbolico, cree un script muy simple que lo llame convertervideo.sh la siguiente linea nada mas:
Opción 1:
mencoder -oac mp3lame -lameopts cbr=128 -ovc xvid -xvidencopts bitrate=1200 video.rmvb -o video.avi
Opción 2:
mencoder -oac mp3lame -lameopts cbr=128 -vf scale=640:272 -ovc xvid -xvidencopts bitrate=1200 -ofps 25 -of avi p-Proposl198.rmvb -o p-Proposl198.avi
le di permiso de ejecucion y lo ejecute y todo esta funcionando correctamente.
