Not exactly. input_SelectES only needs to know about new ES types (ES 
== Elementary Stream), and there we don't need to do anything since 
an MPEG-1 layer III stream is of type MPEG1_AUDIO_ES.

There are two things in an .mp3 file : an mp3 header and an mp3 
elementary stream. The mp3 elementary stream should go just fine. 
What you need to do is to adapt plugins/mpeg_system/input_es.c to 
read the mp3 header as well. We will probably need to talk about this 
some more.
