## Take note that you'll need ffmpeg restricted libraries
## On Ubuntu, you can download and install them from the
## Medibuntu Repository at http://medibuntu.org/
## check the howtos for instruction on how to install them
## you'll need the *-unstripped and *-extra libraries
## 
## You'll also need to have libnotify1 package installed
## Since ffmpeg already outputs tons of messages on the
## terminal, the messages this script outputs will only
## be readable (or even usable) using the desktop
## notification daemon

This will convert videos to MP4 that's optimized and plays on my phone. The said videos should be stored on a directory so this script could parse them.

Requires unstripped codecs from the Medibuntu repository (libavcodec-unstripped-52, libavdevice-unstripped-52, libavformat-unstripped-52, etc.) which contains the MP4 and libfaac Encoders. See: http://ubuntuforums.org/showthread.php?t=1117283 and http://www.medibuntu.org/repository.php

This script also requires the libnotify1 package for the notify-send command (or you can just echo it, instead of using the desktop notification daemon)

Update the ffmpeg statement as needed, check the documentation at http://www.ffmpeg.org/ffmpeg-doc.html
