[Streamsicle-development] ID3v2.3 embedded picture (APIC) support...

[Arion L. <ar...@ar...>]

Attached is a patch to Streamsicle v2.0 that adds support for viewing
pictures embedded within MP3 files.  The ID3v2.3 standard provides a clear
description of how these pictures should be embedded and extracted from an
ID3 frame titled 'APIC'.  The patch included here will display any
embedded picture below the currently playing song -- and in the ID3
details screen.

My motivation for implementing APIC support is that embedding pictures
within MP3 files has been made very easy on my Mac OS X box with iTunes4
(http://www.apple.com/itunes/) and Clutter
(http://www.sprote.com/clutter/).

To see how this patch works, you can check out my Streamsicle feed at:
http://www.arion.net/streamsicle/.  I'm not really planning on having
Streamsicle accessible onside of my home network, so I'll probably take
that link down eventually... and sorry, I don't allow remote users to
connect to the stream.

The cover art pictures in my MP3s are often pretty large (up to 100k or
so).  The <IMG SRC=> tag within the Streamsicle JSP includes a fixed width
attribute to force web browsers to scale the images...

I've had this patch running on my Streamsicle server at home for a few
weeks straight so I think its pretty stable -- extracting a picture is an
autonomous function, no picture data is ever retained in memory by
Streamsicle (other than a flag saying that the song has a picture).

Let me know if you have any questions. Hopefully this patch will make its
way into the Streamsicle CVS tree...
