mp4tools are a set of scripts to encode audio and video in many 
formats. It has presets for most common embedded devices like 
Sony PSP, Apple iPod, Nokia Phones, so you haven't to go in the 
jungle of encoding options, firmware bugs or unsupported 
configurations.

Hot functions are:

 * support for embedded devices;
 * direct rip from DVD;
 * autocrop of black borders to have a bigger visual;
 * audio peak normalization to make audio sound louder.
