Overview
--------

A simple utility to play MPEG audio files (layer I and II) through a 
Techno Trend (etc) DVB card with on-baord MPEG decoder. Useful if (like me)
you have an old Linux box with no sound card!

Installation:
-------------

The directory should reside in the linuxTV distribution, for example:

linuxtv-dvb-1.0.0/apps/elgar-0.1/

...then just cd into elgar-0.1, type make and hope for the best!

Usage:
------

elgar -e|p file [volume]

Options:
--------

-e 	reads in an elementary stream, and adds PES headers as appropriate.
-p 	reads in a PES stream, and sends to the board directly.
volume	in the range 0..255


But hold on, all of my music is in MP3 format....!
--------------------------------------------------

As the decoder chip only supports MPEG audio layers I and II, you'll need 
to convert any other formats into MP2 format first. Fortunately, this is 
not too difficult, just get hold of madplay and toolame, then do something
like the following:

madplay -o wave:temp.wav song.mp3
toolame temp.wav song.mp2
rm temp.wav
elgar -e song.mp2

In fact if you've got another shell handy, you can start playing the MP2 
file before toolame is complete.

Known bugs:
-----------

There is something missing in the code which I think is required, to do with
initialising the board. So after booting your system you may need to run 
another DVB app, vdr for example, before running elgar for the first time.
