Actually I pre preocess the videos, after that they´ll be played with VLC.
So the only output is the command mencoder console output.

I noticed add subtitles takes time, any tip.

This is the command:

mencoder /carpeta_X/pelicula.avi -sub /carpeta_X/pelicula.srt -oac copy
-ovc lavc -o /tmp/pelicula_final.avi -subcp latin1 -font
/usr/share/fonts/msttcore/arial.ttf -subfont-text-scale 2.8

Thanks

Ro
